Description
The MEGA-TMF300-I Series is the top selling meter in our Product Line. The MEGA-TMF300-I Series thermal gas mass flowmeter features a bright, high contrast display of flow rate and temperature. It is powered by 24VDC or 220VAC.
The MEGA-TMF300-I Series thermal gas mass flowmeter is offered in Integral or Remote style. Specify any standard probe length of flow body size. It has a 4-20mA output as well as a pulse output of totalized flow. In addition, MEGA-TMF300-I supports full Modbus compliant RS485 RTU communication.
- Isolated 4-20mA output and pulse output
- Modbus compliant RS485 RTU communications or HART
- Available in 220VAC or 24VDC
- Measures process gas flow rate/total flow and temperature
- Insertion probes: for 2’’ to 80’’ pipe；
- Wide measurement range
- Flow accuracy for gases: ±1.0%
- Working temperature can be up to 350℃
- It has more compact design, which means smaller enclosure and thinner insertion tube probe
- Wide Turndown ratio 100:1
- Cost-effective model
