MF5706-G-20-B-A Thermal Gas Mass Flow Sensor With LCD Digital Display
MF5706-G-20-B-A Thermal Gas Mass Flow Sensor With LCD Digital Display
1. Thermal Mass Measurement: Directly measures mass flow, unaffected by fluctuations in operating temperature or pressure;
2. Dual-Function (Digital Display + Communication): Enables direct flow readings at the site while supporting data acquisition via RS485 connection to a PLC or industrial control system; features include totalizer reset, high/low limit alarms, and password-protected parameter settings;
3. Low Power & Portable: Battery provides over two months of continuous operation; supports on-site calibration of coefficients for specific gases;
4. Compact & Easy to Install: Features a compact, straight-through pipeline design with no moving valve cores, minimizing the risk of clogging.
