Insertion Thermal Gas Mass Flowmeter (BETA-TMF300-I)
Item No.: 15.2
Thermal mass flowmeter, also known as a thermal dispersion or immersible mass flowmeters, are precision instruments used to measure the mass flow of fluid flowing in a closed channel like a pipe or a duct.


The BETA-TMF300-I Series is the top selling meter in our Product Line. The BETA-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 BETA-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, BETA-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
