F221x OEM Insert type thermal mass flow meter

Measuring Range：0(0,1) … 250 Nm/s
Turndown Ratio：1:2500

Characteristics

F221x 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

Typical installation

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

Data logging function with max. 10,000,000 values

Bluetooth function for wireless flowmeter configuration and data transmission

Standard Modbus RTU (RS485) interface, 4 to 20 mA current and pulse output

Insert type F221x: Suitable for pipes with diameters from DN20 to DN1000, and can be installed under pressure via a 1/2″ ball valve
