FTR-1410R Series Multifunction
Female-Threaded Turbine Flow Meter

Basic principle of FTR-1410R multifunctional internal thread turbine flow meter: fluid flows through the sensor housing. Since the blades of the impeller are at a certain angle to the flow direction, the impulse of the fluid causes the blades to have a rotational moment. After overcoming the friction moment and fluid resistance, the blades rotate. After the torque is balanced, the rotational speed is stable. Under certain conditions, the rotational speed is proportional to the flow rate. Since the blades are magnetically permeable It is in the magnetic field of the signal detector (composed of magnet steel and coils). The rotating blades cut the magnetic lines of force and periodically change the magnetic flux of the coil, thereby inducing an electrical pulse signal at both ends of the coil. This signal is amplified and shaped by the amplifier to form a continuous rectangular pulse wave with a certain amplitude, which can be remotely transmitted to the display instrument to display the instantaneous flow and cumulative amount of the fluid. Within a certain flow range, the pulse frequency f is proportional to the instantaneous flow rate Q of the fluid flowing through the sensor.
