Description

Flowma TGF06D-A Air Thermal Mass Flow Meter

Flowma TGF06D-A is based on the thermodynamic principle and can measure air velocity and air volume, There are 2 temperature sensors inside the probe one for temperature measurement, and the other one as a measuring conveyor after heating. Flowma TGF06D-A (also cataloged under OEM code FTM06D) is a compact, digital air thermal mass flow meter and transmitter. It is specifically engineered to measure air velocity, volumetric flow rate, and mass flow in compressed air lines, HVAC ducts, and process gas lines without requiring separate temperature or pressure compensation.

Flowma TGF06D-A Features

Flowma TGF06D-A Temperature difference between the two as a basis for measuring flow rate. When the medium flow rate increases, the temperature difference decreases.
The temperature difference is converted to standard signal output after processing which is why the flow rate can be measured by these two sensors. All-metal housing, suitable for a variety of pipe diameters.

Working Principle

The TGF06D-A relies on Constant Temperature Anemometer (CTA) thermodynamic principles:

Dual Sensors: The probe head houses two RTD temperature sensors. One acts as a reference temperature sensor for the gas, while the other is heated to maintain a constant temperature differential.
Heat Loss Calculation: As air flows past the probe head, it carries away heat from the heated sensor. The electronic module measures the power required to maintain the temperature difference, which directly correlates to the mass flow rate.
