Reading guide: How many types of gas flow meters do you know? Follow us to learn the gas flow meter types and their applications.

What is a gas flow meter?

A gas flow meter is an instrument for measuring gas flow. Installed in the pipeline to record the amount of gas flowing through. Can measure gas, air, nitrogen, acetylene, phosgene, hydrogen, natural gas, nitrogen, liquefied petroleum gas, hydrogen peroxide, flue gas, methane, butane, chlorine, gas, biogas, carbon dioxide, oxygen, compressed air, argon Gas, toluene, benzene, xylene, hydrogen sulfide, sulfur dioxide, ammonia, etc.

What are the flow meters for measuring gas?

Target flow meter

It began to be used in industrial flow measurement in the 1960s. It can measure the flow measurement of gas, liquid, and steam. It is mainly used to solve the flow measurement of high viscosity and low Reynolds number fluid. It has experienced two development stages pneumatic meter and electric meter. These two intelligent target flow meters, SST and SBL, are based on the original strain gauge target flow meter measurement principle, and use the latest chip level II capacitive force sensor as the measurement and sensitive transmission element, while using modern digital intelligence A new type of flow meter developed by processing technology.

Vortex flow meter

The vortex flow meter is mainly used for flow measurement of industrial pipeline media fluids, such as gas, liquid, steam, and other media. It is characterized by small pressure loss, large measuring range, and high precision. It is almost not affected by parameters such as fluid density, pressure, temperature, and viscosity when measuring volume flow in working conditions. No moving mechanical parts, so high reliability and low maintenance. Instrument parameters can be stable for a long time.

V-cone flow meter

The V-cone flow meter is widely used in petrochemical, natural gas, and other fields due to its simple structure, firmness, easy replication, strong versatility, and low price. The V-cone flow meter overcomes the defects of standard orifice plates, Venturi tubes, nozzles, and other throttling devices, such as easy wear, large pressure loss, small range (turndown ratio), high site installation conditions, and long straight pipe sections, etc. It can accurately measure the flow of various fluids in a wide range of Reynolds numbers. Can be widely used in various fields, suitable for measuring water, oil, various liquids, steam, air, natural gas, coal gas, petroleum gas, organic gas, oil residue, etc.

Orifice Flow Meter

The orifice plate flow meter is a high-range ratio differential pressure flow device composed of a standard orifice plate and a multi-parameter differential pressure transmitter (or differential pressure transmitter, temperature transmitter, and pressure transmitter), which can measure gas flow. The flow rate of steam, liquid, and natural gas is widely used in process control and measurement in the fields of petroleum, chemical industry, metallurgy, electric power, heating, water supply, and so on.

Verabar flow meter

Suitable for high-precision flow measurement of gases, liquids, and steam. The Verabar is a differential pressure, rate-averaging flow sensor that measures flow through the differential pressure generated by the sensor in the fluid. The Verabar reflects the real flow velocity of the fluid, with an accuracy of ± 1.0% and a repeatability of ± 0.1%. The outstanding advantage of Verabar is that it outputs a very stable and pulsation-free differential pressure signal.

Which industries need to use gas flow meters

The use of gas flow meters is very extensive, and gas flow meters are used in many industries. Supmea will introduce the specific application fields of gas flow meters for you:

1. Industrial production process

Flow meters are one of the major types of instruments in process automation instruments and devices. Gas flow meters are widely used in metallurgy, electric power, coal, chemical industry, petroleum, transportation, construction, textile, food, medicine, agriculture, and environmental protection, and Our daily life and other fields are important tools for developing industrial and agricultural production, saving energy, improving product quality, improving economic efficiency and management level, and occupy an important position in the national economy. In process automation instruments and devices, flow meters have two major functions: as a detection instrument for a process automation control system and as a total meter for measuring the number of materials.

2. Energy metering 

Energy is divided into primary energy (coal, crude oil, coal bed methane, petroleum gas, and natural gas), secondary energy (electricity, coke, artificial gas, refined oil, liquefied petroleum, steam) and energy-carrying medium (compressed air, oxygen, nitrogen), etc. Energy metering is an important means to scientifically manage energy, realize energy saving and consumption reduction, and improve economic benefits. Flow meters are an important part of energy metering instruments. Commonly used sources such as artificial gas, natural gas, steam, and oil all use an extremely large number of flow meters. Gas flow meters are an indispensable tool for source management and economic accounting.

3. Environmental protection engineering

The discharge of flue gas, waste liquid, sewage, etc. seriously pollutes the air and water resources, and seriously threatens the human living environment. To control air and water pollution, management must be strengthened, and the basis of management is the quantitative control of pollution. Supmea develops and produces gas flow meters with strong stability, high precision, and long service life.
