High frequency signals (3-4kHz) can be obtained, with strong signal resolution;

■ Wide range, with a medium to large caliber of up to 1:20 and a small caliber of 1:10;

Transformer oil flowmeterWorking principle

The fluid flows through the sensor housing, and due to the angle between the blades of the impeller and the flow direction, the fluid's impulse force causes the blades to have a rotational torque. After overcoming the friction torque and fluid resistance, the blades rotate. After the torque is balanced, the speed is stable. Under certain conditions, the speed is proportional to the flow velocity. Due to the magnetic conductivity of the blades, they are in the magnetic field of the signal detector. The rotating blades cut the magnetic field lines and periodically change the magnetic flux of the coil, causing electrical pulse signals to be induced at both ends of the coil. This signal is amplified and shaped by an amplifier to form a continuous rectangular pulse wave with a certain amplitude, which can be transmitted to a display instrument to display the instantaneous flow rate or total amount of the fluid.
