Турбинный расходомер с наружной резьбой

The basic principle of the FTR-1600E external thread turbine flowmeter: the fluid flows through the sensor housing. Because the blades of the impeller have a certain angle with the flow direction, the impulse of the fluid makes the blades have a rotating moment. After overcoming the friction torque and fluid resistance, the blades rotate. After balance, the speed is stable. Under certain conditions, the speed is proportional to the flow rate. Because the blade has magnetic permeability, it is in the magnetic field of the signal detector (composed of permanent magnets and coils). The rotating blade cuts the magnetic field lines periodically. The magnetic flux of the coil is changed, so that electrical pulse signals are induced at both ends of the coil. This signal is amplified and reshaped by the amplifier to form a continuous rectangular pulse wave with a certain amplitude, which can be transmitted to the display instrument remotely to display the instantaneous flow rate and flow rate of the fluid. Cumulative amount. Within a certain flow range, the pulse frequency f is proportional to the instantaneous flow Q of the fluid flowing through the sensor.
