Description

Flowma PHD and PTF 330 Pitot Tube Flowmeter are often used in the measurement of flow. With several pressure-detecting holes on the PTF, we can get the average of the flow inside the duct and improve the problem that happened in the flow measuring where disturbance occurs when there is no adequate space inside the straight inlet.

Flowma PHD and PTF 330 Pitot Tube Flowmeter Descriptions

PTF is a probe we inserted into the duct(along with the whole diameter) to measure the flow. When the probe encounters the flow, will
sense and get the average total pressure P1 on the windward side and static pressure P2 on the leeward. AFMT then gets the flow velocity by measuring the difference between total pressure and static pressure(i.e.) dynamic pressure(?P) and flow average velocity(V).

PHD330 differential pressure transmitter is designed on the MEMS hot wire anemometer architecture, which has very good zero point stability and small differential pressure detection capability, high-pressure resistance. The transmitter uses the pressure difference to pass a very small amount of gas through the airflow channel of the sensor body. Combined with the integrated circuit to convert into a differential pressure signal.
