Gas measurement by qtmf thermal gas mass flowmete

  Qtmf series thermal gas mass flowmeter is an instrument for measuring fluid flow based on the principle of heat conduction
The flowmeter uses the constant temperature difference method to accurately measure the gas mass flow
Thermal gas mass flowmeter has the advantages of small volume, high digitization, convenient installation and accurate measurement
Qtmf series pipeline thermal gas mass flowmeter has been equipped with process pipeline with the same inner diameter as the field pipeline when leaving the factory
The connection with the on-site pipeline is flange connection or threaded connection
The flange standard shall comply with the national standard GB / t9119-2000
Applicable pipe diameter of pipe section sensor: DN15 ~ 2000mm

Qtmf series thermal gas mass flowmeter is an instrument for measuring gas flow based on the principle of thermal diffusion
The sensor consists of two reference level RTDS
One is the speed sensor RH and the other is the temperature sensor RMG for measuring the change of gas temperature
When the two RTDS are placed in the measured gas, the sensor RH is heated and the other sensor RMG is used to sense the temperature of the measured gas
As the gas flow rate increases, the gas flow takes more heat away and the temperature of sensor RH decreases
Qtmf series thermal flowmeter is a flow meter designed based on the principle of thermal diffusion That is, when the fluid flows through the heating object, the heat loss of the heating object is proportional to the fluid flow The sensor of this series of flowmeter has two standard RTDs, one is used as a heat source and the other is used to measure the fluid temperature
When the fluid flows, the temperature difference between the two has a linear relationship with the flow, and then this relationship is converted into the linear output of the measured flow signal through microelectronic control technology
