DESCRIPTION :
Gas turbine flowmeter uses a turbine for measurement. It first converts the flow rate into the rotational speed of the turbine, and converts the rotational speed into an electrical signal proportional to the flow rate.Gas turbine flowmeter is used to detect instantaneous flow and total integrated flow. Its output signal is frequency, which is easy to digitize.
Gas turbine flowmeter( flow transducer) is a high accuracy flow sensor .It can be used in the fields of air,natural gas other gas to be measured.Several output and display methods can be selected.
The induction coil and the permanent magnet are fixed on the housing together. When the ferromagnetic turbine blade passes the magnet, the reluctance of the magnetic circuit changes, thereby generating an induction signal.
The signal is amplified and reshaped by the amplifier and sent to the counter or frequency meter. The total accumulated flow is displayed. At the same time, the pulse frequency undergoes frequency-voltage conversion to indicate instantaneous flow.
