F222x Pipe Type OEM Type Thermal Mass Flow Meter
Product Advantages：Ultra-wide flow measuring range Measurement Range：0(0.1) … 250 Nm/s Turndown Ratio：1:2500
F222x flow meter is based on thermal measurement technology. It can measure the standard flow, mass flow, consumption, and gas temperature directly No moving parts, stable signal, vibration proof, high reliability, long-term measuring accuracy Full-digital signal processing is used instead of the conventional analog bridge design, resulting in a wider range and more accurate measurement. The low measuring limit can reach 0.1Nm/s, and the turndown ratio can reach 1:2500. It has a wider measuring range than common flow meters on the market, making it suitable for measuring extremely volatile flow, low-flow bypass, and the gas consumption of single equipment. With the innovative, intelligent diagnosis technology, it can sense the sensor pollution online and protect the sensor from overheating
- Full-digital signal processing, higher accuracy, long-term stability
- Based on the thermal flow measurement principle, it’s not required to compensate gas pressure and temperature, integrated temperature measurement
- With an ultra-wide 1:2500 turndown ratio, the measuring range is from 0.1 Nm/s to 250 Nm/s
- The fully isolated electrical structure can completely filter out field disturbance
- The capacitive touch 1.5″ IPS LCD with an ultra-wide viewing angle
- Standard Modbus RTU (RS485) interface, 4 to 20 mA current and pulse output
- Pipe type F222x:
Pipe size: DN15, DN20, DN32, DN40, DN50, DN65, DN80
