Related Description: The scene shows the type of air flow meter, also called the integration of intelligent display vortex flowmeter, refer to the head of the table is equipped with LCD can display the cumulative flow, instantaneous flow rate and other parameters can also be output pulse signal or 4-20mA standard current signal. The meter uses 3.6V high-energy lithium battery-powered, live without external power supply, easy installation, low prices. Field display type vortex flowmeter is generally used for measuring ordinary gas mass flow rate of the liquid or vapor volume flow (density using the set value).
