Flange Type Thermal Gas Mass Flowmeter

The hot gas mass flow meter is a new type of instrument used to measure and control the mass flow of gas. It is based on the principle of thermal diffusion (heat conduction). The instrument uses the constant temperature difference method to measure the gas accurately. It can be used in petroleum, Gas, oxygen, nitrogen, argon, helium, hydrocarbon gas, natural gas, gas and other gas, such as iron and steel, metallurgy, electric power, light industry, medicine, environmental protection and other industrial sectors.

Features
1. The gas flow measurement without temperature and pressure compensation, measurement is convenient and accurate, can get the gas mass flow or standard volume flow.
2. Wide range ratio of 100: 1 or more, can be used for gas leak detection, especially in the large diameter, low flow rate, flow range changes and small flow measurement has obvious advantages.
3. Seismic performance is good, the measurement accuracy is not affected by vibration.
4. Long life, the sensor is no moving parts and pressure sensing parts, easy to install, easy maintenance.
5. Response speed, pressure loss is small, good repeatability.
6. The use of digital design, the overall digital circuit measurement, LCD display intuitive and clear, accurate measurement.
7. With RS485 communication module or HART protocol, with the host computer can be centralized management.
