Small flow digital gas mass flowmeter and controller

For customers with higher precision requirements for small flow digital gas mass flow meters and controllers, we provide measurement grade accuracy (± 0.5% reading accuracy). Through the precise compensation of pressure and temperature sensors built into the product and core algorithms, the meter exhibits higher performance in low zero point, temperature, and pressure drift. At the same time, there are four built-in standard temperature options (0 ℃, 15 ℃, 20 ℃, 25 ℃) to choose from, and real-time display of five major parameters: temperature, pressure, standard flow rate, operating flow rate, and cumulative flow rate.
