TGF260 Thermal Gas Mass Flowmeter
Description
TGF260 thermal mass flowmeter adopts the principle of constant temperature difference. One probe measures the temperature Tl of the gas to be measured, and the other probe adds constant temperature difference △T on the basis of other temperatures TI. When the gas flows through the velocity probe and takes away the heat, it is necessary to compensate the electric power to keep the △T constant, and this compensated electric power is directly proportional to the gas mass flow: Qm=H/(Cp×AT)Qm is the mass flow; H is electric power.
Main Feature:
No moving parts, no blockage, fast response and high measurement accuracy.
Intelligent self-diagnosis, easy maintenance of products.
No straight pipe section requirements, easy to install and use.
The lower limit is as low as 0.1Nm/s, and the range ratio is as wide as 1:100.
Viewing and operating the flowmeter through the mobile APP is intuitive and convenient.
Multi-parameter measurement, which can measure flow, temperature and pressure, and save cost.
Various output signals: 4-20mA current, pulse output and RS485 communication.
Optional built-in 5000mA lithium battery can meet 16-hour field measurement.
Support multiple communication modes (BlueTooth, Modbus-RTU).
