◆ No need for temperature and pressure compensation, directly measure mass flow rate
◆ Suitable for large caliber and small flow rate
◆ Neglecting pressure loss
◆ No movable parts, high stability
◆ Corrosion resistant sensor, compatible with corrosive gases
measuring principle
The Tmass gas mass flowmeter is calibrated using a standard precision wind tunnel and follows the golden law of thermal dissipation (cooling) effect based on the principle of constant temperature difference. It can display both flow rate and temperature simultaneously. Low flow rate response is sensitive, and high flow rate can also achieve good accuracy. Even at high temperatures, it can achieve good temperature difference and stability.
application
Air, natural gas, biogas, coal gas, dry chlorine gas, oxygen, flue gas, torch gas, argon gas, and other dry gases.
