What fluid media can the elliptical gear flowmeter be applied to?

The thermal gas mass flowmeter is used for the measurement of a single component of gas or a fixed proportion of mixed gas, and has been widely used in petroleum, chemical, semiconductor, medical instruments, biological engineering, combustion control, gas distribution, environmental monitoring, precision instruments, scientific research, metrology, food, metallurgy, aerospace and other fields.

The structure of an electromagnetic flowmeter mainly consists of multiple key components, which work together to measure the flow of conductive liquids. The following are the main structural components and functions of the electromagnetic flowmeter:

1. Vibration effect

Compressed air is generated by air compressor or high pressure fan. When these devices are in operation, they all have varying degrees of vibration, and sometimes the vibration is relatively strong, and this vibration is transmitted through the connecting pipe. When selecting and determining the position of the vortex flowmeter, this influencing factor should be fully considered. In various detection methods, the anti-vibration performance of the instrument is not the same due to different detection components. For the vortex street of the detection element, the vibration resistance can reach 0.5~1G. When determining the installation position of the vortex flowmeter, it should be as far away from the power equipment such as air compressors and fans as possible.

Ultrasonic flow meters have become integral tools across various industries due to their versatility and non-intrusive nature. One prominent application of ultrasonic flow meters is in the field of water and wastewater management. Municipalities and water treatment plants employ these meters to measure the flow rates of water in pipes without disrupting the flow itself. The non-contact nature of ultrasonic technology minimizes the risk of contamination and allows for accurate measurement, contributing to efficient water distribution and conservation efforts.

The thermal gas mass flowmeter is an instrument that uses the principle of heat conduction to measure flow. The instrument adopts constant temperature difference method for gas mass flow sensor part consists of two reference platinum resistance temperature sensors. Using a bridge loop, one sensor measures the flow temperature and the other maintains a constant temperature difference above the fluid temperature, allowing flow measurement under high temperature and high pressure conditions.

Electromagnetic flow meters offer several advantages, making them a popular choice in various industrial applications. Here are some of the key advantages of electromagnetic flow meters:

Coriolis mass flowmeters offer several benefits over other flow measurement technologies, making them widely used in various industries. Some key advantages include:

Intelligent precession vortex flowmeter is a new type of gas flow meter developed by our company. The flowmeter integrates the function of flow, temperature and pressure detection, and can automatically compensate the temperature, pressure and compression factor. It is an ideal instrument for gas measurement in petroleum, chemical industry, electric power, metallurgy and other industries.

The mass flowmeter directly measures the mass flow of the medium through the flowmeter, and can also measure the density of the medium and indirectly measure the temperature of the medium. To accurate measurement data, there can be no influencing factors, but when using the flow meter can not avoid the influence of some factors, in short, some factors affect the measurement and solution of the mass flow meter.

Due to the compressibility of the gas, its flow measurement is more complex than that of the liquid, and the output signal of the vortex flowmeter is related to the gas density in addition to the input signal, and the density of the gas is a function of temperature and pressure (referred to as temperature and pressure).

Electromagnetic flowmeters exhibit remarkable performance even in challenging environmental conditions. Their construction materials are often chosen for their corrosion resistance, enabling these devices to withstand harsh chemicals and extreme temperatures. This robustness ensures continuous and reliable operation, making electromagnetic flowmeters suitable for demanding industrial applications where other flow measurement devices might struggle to perform consistently.

At present, there are many misunderstandings about steam measurement in China, and many users often think that buying a high-price flowmeter can get accurate measurement results. The measurement of steam is different from other fluids such as water, air and other media, and there are many factors affecting its measurement in the actual measurement. Therefore, there is often a phenomenon that the flow meter itself is qualified, but the actual measurement is not “allowed”. So what’s the problem with these factors?

When selecting a vortex flowmeter, it is necessary to provide the measured medium, product density and viscosity, working condition temperature, working condition pressure (, maximum flow rate, normal flow rate).

Check Power Supply: Ensure that the flowmeter is receiving power from the power supply source. Verify that the power supply is operational, and check the connections between the flowmeter and the power source. If necessary, measure the voltage at the flowmeter terminals to confirm proper power supply.

Like the flue gas, this medium has a higher temperature, contains more impurities such as solid dust, the general application of large caliber, flow rate range is relatively wide, so the measurement is more difficult, so in the selection and use of flue gas flow timing should pay attention to the characteristics of the power plant flue wind speed, pay attention to the principle of choosing sensors, It is also necessary to pay attention to the wear resistance, corrosion resistance, dirt resistance and high temperature resistance of the sensor, and select the appropriate measurement position to ensure the measurement accuracy.

vortex flow meters offer a cost-effective solution for flow measurement. Their relatively simple design, coupled with low maintenance requirements, contributes to a lower total cost of ownership over the life of the instrument. This cost efficiency, combined with their accuracy and reliability, positions vortex flow meters as a favorable choice for industries seeking optimal performance without compromising on budget considerations.

Ultrasonic flowmeters can generally operate normally for a long time without maintenance in the future. After that, maintenance and daily inspections are required. Not receiving the signal or having a too weak signal are both minor issues. So there’s no need to be surprised if it occurs. Just do the following steps carefully and it will be easy to solve.

When using electromagnetic flowmeters in the field, it’s important to perform regular checks and maintenance to ensure accurate and reliable flow measurements. Here are some key parameters to check and consider in the field for electromagnetic flowmeter use:

At the heart of a thermal mass flow meter is a sensor that heats up a portion of the gas stream while monitoring the temperature difference between the heated and unheated sections. As the gas flows over the heated sensor, it carries away heat, and the temperature difference provides a direct measurement of the mass flow rate. The beauty of this method lies in its ability to provide accurate readings across a wide range of flow rates, from low to high velocities, ensuring versatility and reliability in various industrial settings.

There are often some error factors in the calibration and use of flowmeter coefficient, which affect the accuracy of gas metering. The following are the factors that affect the accuracy of the steam flowmeter.

In the industrial field, companies need to use natural gas, hydrogen and other gas in many process production, sometimes also need oxygen, nitrogen, argon and other made of gas, this part of the gas cost needs to be controlled and monitored, and the selection of monitoring instruments need to consider various issues:

Another important requirement of the electromagnetic flowmeter: how to accurately select the lining material, the lining material of the electromagnetic flowmeter should be selected according to the erosion, wear and temperature of the measured medium.

The external clamp-on ultrasonic flowmeter is a flow meter that is highly suitable for full pipe measurement in pipelines. It features easy installation, non-contact operation, and can measure the flow of large-diameter media as well as media that are difficult to contact and observe. Its measurement accuracy is very high and is almost unaffected by various parameters of the measured medium. It can especially solve the flow measurement problems of highly corrosive, non-conductive, radioactive and flammable and explosive media that other instruments cannot handle.
