Gas flow meter
is a kind of gas flow measurement devices that measure the flow of a gas. The gas
flow sensors are installed in the pipeline to display and record the amount of
gas passing through the pipelines. Gas flow meters can measure gas, air,
nitrogen, acetylene, phosgene, hydrogen, natural gas, nitrogen, LPG gas,
hydrogen peroxide, flue gas, methane, butane, chlorine, gas, biogas, CO2,
O2, compressed air, argon Gas, toluene, benzene, xylene, hydrogen
sulfide, sulfur dioxide (SO2), ammonia,propane gas flow meter and so on.
There are many gas flow meter types,the following are the common gas flow meters that Silver Automation Instruments often recommend to customers:
Thermal Mass flow meter
The thermal Mass flow meter is designed based on the principle of thermal diffusion. The flow sensor uses the constant temperature difference method to accurately measure the gas.It has the advantages of small size, high intelligence, convenient installation and accurate measurement. Thermal mass flow transmitter does not require external temperature and pressure compensation, and the measurement is convenient and accurate, the mass flow rate of the gas or a standard volume flow can be obtained. The wide range ratio of the thermal dispersion flowmeter measures gases with flow rates as high as 120 Nm/s down to 0.1 Nm/s and can be used for gas leak detection. The immersible mass flow meters has good seismic performance and long service life. The gas flow sensor has no moving parts and pressure sensing parts and is immune to the influence of vibration on the measurement accuracy. Factory automation and integration can be achieved by using RS-485 communication or HART communication. Digital thermal mass flow meter can be used for compressed air flow meters, propane gas flow meter,biogas flow meters, LPG flow meters, nitrogen flow meters, oxygen flow meters.
Gas turbine flowmeter
Gas turbine flowmeter model is suitable for measuring various gases in various gas and industrial fields, such as natural gas, city gas, LPG, propane, butane, air, nitrogen, etc. The gas flow sensor has high accuracy and good repeatability, and is especially suitable for custody transfer. The gas turbine flowmeter is a kind of speed flowmeter with low pressure loss, high accuracy, low starting flow, large turndown ratio, good seismic and pulsation resistance. The gas flow instruments solled by Silver Automation Instruments is a digital gas flowmeter with electronic display of instant flow and total flow. It can output pulse or 4-20 mA, and can have RS485 communication to meet various industrial control needs of customers.
It is mainly used for flow measurement of industrial pipeline medium fluids, such as gases, liquids, vapors and other media. It is characterized by small pressure loss, large measuring range and high precision. It is almost unaffected by parameters such as fluid density, pressure, temperature and viscosity when measuring the volume flow rate. No moving mechanical parts, so the reliability is high and the maintenance is small. The flow instruments use a piezoelectric stress sensor with high reliability and can work in the operating temperature range of -20 ° C ~ +250 ° C. There are analog standard signals and digital pulse signal outputs, which are easy to use with digital systems such as computers. It is a relatively advanced and ideal flow meter.
Rotameter (Variable Area Flow meter)
The metal tube rotameter is a variable area flow meter based on float position measurement. It adopts all-metal structure, has the characteristics of small volume, small pressure loss, large range ratio (10~20:1), convenient installation and maintenance, etc. It is widely used in complex and harsh environments of various industries, for small flow, low flow rate. Silver Automation Instruments also sell digital rotameters with digital display to show instant flow and total flow, it can be made into rotameter with flow transmitters which can have alarm outputs, 4-20mA outputs, RS485 communication and so on.
