Oval Gear Flow meter Manufacture

 Why Should You Invest In Oval Gear Flow Meter For Filling Oil Containers?    When you are working in any industry, for an instance let us consider oil packaging industry, you are entitled to take orders and fill the containers with oil. Such a task requires a lot of preciseness and the men should be careful enough to avoid the wastage of resources, oil as well as their time. Often, there are a plethora of workers who measure the amount individually, which can further be overwhelming and tedious. Not to forget, the time it takes to fill the different containers. To combat such problems, oval gear flow meter is regarded as an effective solution.  Now you must be wondering what exactly is oval gear flow meter? Well, it is a kind of direct volume displacement meter that stands to fulfill the purpose of providing its user with much-needed oil-filling accuracy as well as longevity. Moreover, it is designed in such a way that it offers accurate results irrespective of the fact whether the container is filled with liquid that changes in temperature, viscosity or pressure. Now let us enlighten our users on the topic of how it operates. It consists of a unit, the two-toothed oval wheels, which starts revolving the moment liquid is passed into the container. The exact volume is further depicted by the number of revolutions this unit undertakes. The rotations are detected by the presence of a sensory element.   Often, you must have encountered other oil measuring equipment and tools and may be confused which one is the best fit for you. Don’t be confused anymore as we have certain research-based facts which can help you in your decision-making process. The oval gear meters require a minimal amount of maintenance as well as recalibration as it doesn’t have any movable components in it. Moreover, it’s robust built allows these tools to withstand any environment or harsh climate, thus, continuing to provide its users the benefits it was employed for in the very first place.  Furthermore, you know how oils are important to our living. It is like an inseparable part of our lives. No matter what we do, they find their role in it. But there are certain places that face the shortage of oil volume and its related challenges. In such times, we can’t risk to waste any more of its quantity or overfill any container out of dire carelessness. Apart from this, filling such containers requires huge responsibilities and any failure in conducting this could result in a huge problem and loss. This is where oval gear flow meter finds its usefulness.   It transports a measured amount of liquid volume into different chambers, thus relieving man from a lot of headaches and measuring hassles. Another important fact that needs to be highlighted is that the manufactures in Europe and Japan offer these products at high prices, which hits hard on the pockets of medium and small-sized manufacturers. Therefore, it is advisable to purchase it from the China-based manufacturers as they offer not only high-quality products which are infused with the latest technology but the products are sold at the competitive prices. If you are looking  for these machines or tools, then the China-based

are the best option for you.

Pressure transmitter application and selection

1. Overview

In all kinds of instruments, Pressure transmitters are the most widely used, transmitter is generally divided into pressure transmitter and differential pressure transmitter (DP transmitters). Transmitter is used to measure pressure, differential pressure, vacuum, liquid level, flow and density. There is 2- wire system and 4- wire system transmitters, 2-wire pressure transmitters are more commonly used. There are pneumatic and electric transmitters, most of the used pressure transmitters are electric transmitter; In addition, according to the application situation there are intrinsically safe type and explosion-proof type; According to the application conditions, the main types of transmitter are as follows:

Low pressure/low differential pressure transmitter; middle pressure /differential pressure transmitter; High pressure/high differential pressure transmitter; Absolute pressure/vacuum/negative pressure differential pressure transmitter; High temperature/pressure differential pressure transmitter; Corrosion/pressure, differential pressure transmitter; Easy crystallization/pressure, differential pressure transmitter.

The selection of transmitter is usually based on installation condition, environment condition, and instrument performance, economy and using medium. The practical application is divided into direct measurement and indirect measurement. Its uses include process measurement; process control and device interlock etc. The common transmitter includes common pressure transmitter, differential pressure transmitter, single hair orchid transmitter, double hair orchid transmitter, inserted hair orchid transmitter and so on.

2. Introduction to pressure/differential pressure transmitter

Pressure transmitter and differential pressure transmitter measure pressure and differential pressure (the difference between two pressures) by name alone, but they can measure a lot indirectly. For example, the pressure transmitter can measure the liquid level in the equipment in addition to the pressure. A pressure transmitter is required to measure liquid level in a pressure vessel. When measuring the liquid level of the pressurized container, two pressure/differential pressure transmitters can be considered, namely, one for the lower limit and one for the upper limit. Their output signals can be reduced to measure the liquid level. It can also be used to measure the density of a medium without changing the liquid level and pressure value in the container. The measuring range of the pressure transmitter can be very wide, from absolute pressure 0 to more than 100 MPa.

In addition to measuring the differential pressure of two pressure measuring devices, differential pressure transmitter can also coordinate with various throttling elements to measure the flow rate of medium fluid. It can directly measure the liquid level of the pressure vessel and the pressure and negative pressure of the atmospheric pressure vessel.

3. Selection principle

The selection of pressure/differential pressure transmitter is mainly based on: the property index of the medium under test shall prevail, and it shall save money and facilitate installation and maintenance. If the measured medium is high viscosity, easy to crystallize, strong corrosion, it must use an isolated transmitter.

When selecting the model, it is necessary to consider the corrosion of the monitored flow medium to the metal of the film box. The material of the film box must be selected, otherwise the outer film will be corroded and damaged in a short time after use, and the equipment or personal accident will be caused by the corrosion of the falan. The film box of the transmitter is made of ordinary stainless steel, 304 stainless steel, 316/316l stainless steel, tantalum, etc.

When selection should consider the temperature of the measured medium, if the temperature is high, up to 200 ℃ ~ 400 ℃, should choose high temperature type, or silicone oil will produce vaporizing expansion, making measurement is accurate.

When selecting the type, the working pressure level of the device should be considered, and the pressure level of the transmitter must be consistent with the application situation. From an economic point of view, the material of outer film box and insert part is quite important, want to choose appropriate, but connect hair orchid can reduce material requirement, if choose carbon steel, chromium-plated etc., can save a lot of money.

Advantages and disadvantages of thermal mass flowmeter

Principle
Thermal Mass flowmeter (TMF)is usually called Calorimeter flow meter in China, outside heat source heating is the use of fluid Flow through the pipe when the temperature field changes to measure fluid Mass Flow, or by heating fluid fluid temperature rise of a certain value, the amount of energy needed and the relationship between the fluid quality to measure fluid Mass Flow rate of a Flow meter. Usually used to measure the mass flow of gas. Low pressure loss; Large flow range; High precision, high repeatability and high reliability; Immovable parts and can be used to monitor and control extremely low gas flow. It has a long history of measuring mass flow of a fluid by using heat (or temperature) changes in a heated fluid. The early TMF directly put the coil and temperature measuring elements into the fluid and directly contacted the fluid. As a contact flowmeter, its industrial application was greatly restricted because it could not solve the problems of mouth erosion, wear and explosion protection.

thermal mass flow meter China

Application
1. Gas flow measurement of steel works and coking plants;
2. Measure the air flow of the boiler and measure the secondary air flow;
3. Measurement of smoke flow from chimney;
4. Measurement of organic gas flow in water treatment;
5. Measurement of gas flow during production of cement, cigarette and glass factory;
6. Measurement of compressed air flow;
7. Gas flow measurement of natural gas, gas, liquefied gas, torch gas, hydrogen and other gases.
Classification
Thermal mass flowmeter can be divided into contact type and non-contact type according to different heat source and temperature measurement mode.
1. Contact thermal mass flowmeter
The mass flowmeter heating element and temperature measuring element in be current of the pipe body, and direct contact with fluid is often referred to as Thomas flowmeter, suitable for measuring the larger mass flow of gas. Because of heating and measuring element and the current direct contact with the body, so the components susceptible to fluid corrosion and wear and tear, that affect the instrument sensitivity and service life. It is not suitable for measuring high velocity and corrosive fluid, which is the shortcoming of contact type.
2. Non-contact thermal mass flowmeter
The heating and temperature measuring elements of the flow meter are placed outside the fluid pipe, and they do not contact with the flow measured directly, which overcomes the disadvantages of contact type.
Advantages
The thermal mass flowmeter can measure the small flow rate at low velocity (gas 0.02~2m/s). The immersed thermal mass flowmeter can measure the low ~ medium high flow rate (gas 2~60m/s), and the inserted thermal mass flowmeter is more suitable for large pipe diameter.
The thermal mass flowmeter has no moving parts and no heat distributed instruments with shunt pipes. Although the thermal distributed instrument and immersion instrument with a shunt pipe are equipped with a blocking device in the measuring pipe, the pressure loss is not large.
The performance of thermal mass flowmeter is relatively reliable. Compared with the derived mass flow meter, there is no need for temperature sensor, pressure sensor and calculation unit, but only flow sensor.
Thermal mass gas flow meter instruments are used for H2, N2, O2, CO, NO and other diatomic gases that are close to ideal gases. They are directly calibrated with air instead of these gases. For single atomic gases such as Ar and He, the multiplier coefficient is 1.4. For other gases, the specific heat capacity can be converted, but the deviation may be slightly larger.
The specific heat capacity of a gas varies with the pressure temperature, but a small change near the applied temperature pressure can be considered a constant.
Disadvantages
The thermal mass flowmeter is slow in response. Where the measured gas component changes greatly, the measurement value will change greatly due to the change of cp value and thermal conductivity. For small flow, the meter will bring considerable heat to the gas measured. For the thermal distributed mass flowmeter, if the measured gas affects the measured value of the scale layer deposited on the pipe wall, it must be cleaned regularly. It has the shortcoming of easy clogging to the fine tube instrument, which can not be used in general. The use of pulsating flow will be limited. The thermal mass flowmeter for liquids is also limited to viscous liquids.

Advantage of radar level transmitters

The radar level meter produced by silver automation instruments is suitable for non-contact continuous measurement of liquid, slurry, particle material and block material, and is suitable for large temperature and pressure changes. The presence of inert gases and volatile gases. The radar level transmitter adopts the measurement method of microwave pulse and can work normally within the range of industrial frequency band. The beam is low in energy and can be installed in a variety of metal, non-metal containers or pipes, which is harmless to the human body and the environment.

The product works by transmitting and receiving extremely short microwave pulses with very low energy through an antenna system. Radar waves travel at the speed of light. The running time can be converted into the object position signal by electronic components. A special time extension method ensures stability and accurate measurement in a very short period of time. Even in the case of complex working conditions, there are false echoes. The new micro-processing technology and debugging software of zui can also accurately analyze the echo of the object position.

What are the advantages of radar level transmitters products? The specific advantages are as follows:

1. Can accurately measure and be continuous

This is mainly because the propagation mode of radar object level meter signal wave is the electromagnetic wave, so it will not be affected by the environment and may not be contact measurement.

2. Interference callback can be suppressed

This is the function of radar object level meter itself, very practical.

3. Accurate measurement, materials can be recycled and reused

Because it is not affected by the environment, it will not affect the measurement results, and the material of the radar object level meter is stable and will not change its property.Yes, so you can recycle and save resources.

How to improve the measurement accuracy of gas turbine flow meter

Gas turbine flow meter has the advantages of high sensitivity, good repeatability, wide range ratio and high precision. It has been widely used in natural gas natural gas custody transfer and process measurement and even as a standard instrument for quantity transfer. With the full development of China's urban gas engineering and the continuous improvement of gas commercial trade and handover measurement requirements, gas turbine flow meters have gradually become one of the preferred instruments for commercial gas trading and handover measurement in China.

      The gas turbine flow meter is a speed flow meter that uses gas to drive the impeller of the flow meter. The speed of rotation of the impeller is proportional to the volumetric flow of the fluid. According to the principle of electromagnetic induction, the magnetic sensor is used to induce the volume of the fluid from the synchronously rotating impeller. The pulse signal proportional to the flow rate is processed to obtain the volume flow rate. The measurement accuracy is high, the accuracy level can reach 1.0 level, 1.5 level; the range ratio is wide, generally 1:20 measurement range is wide; the structure is compact and light, the installation and maintenance are convenient, the requirements of the straight pipe section are low, and can be used for medium and high pressure measurement. .

Turbine flow meters also have the following disadvantages: there are movable parts, which are easy to damage, the bearing of the key parts is easy to wear, the dirt resistance is poor, the cleaning degree of the medium is high, and it is difficult to maintain the calibration characteristics for a long time, and regular calibration is required. The causes of the error are: the quality of the meter itself, the design selection is unreasonable, the installation is not in place, and the maintenance during operation is improper.

      How to control the error? Correctly determine the location and specifications of the flow meter. Due to the inertia of the turbine flow meter turbine, it is not suitable to use in the case of frequent flow fluctuations; otherwise the measurement accuracy will be reduced. To accurately estimate the peak-to-valley value of the gas volume and the pressure of the medium, the flow meter specifications are correctly determined.

     The filter must be installed before the gas turbine flow meter; the filter should be kept clean. If the filter is found to be clogged (can be judged by the pressure difference between the filter inlet and outlet), the filter should be cleaned in time, if not equipped with a differential pressure gauge ,please Clean the gas meter once a month. To ensure the requirements of the straight pipe section, especially in the case of a reduced diameter or a half open valve in front of the table. During installation, the gasket shall not protrude into the pipeline, and the flow meter and the pipeline axis shall not be visually inspected and shall not cause installation stress. Always clean all impurities in the pipe during installation to prevent the bearing and turbine from getting stuck.
