AOLWGY liquid turbine flowmeter
◆measuring principle
The product utilizes fluid flow through a sensor. The blades of the impeller are angled relative to the flow
direction, and the impact force of the liquid generates a torque that overcomes friction and fluid resistance, causing
the blades to rotate. Once the torque is balanced, the rotational speed stabilizes. Under certain conditions, the
rotational speed is directly proportional to the flow rate. The magnetic conductivity of the blades, when they are in the
magnetic field of the signal detector, causes them to cut through magnetic flux lines, generating periodic electrical
pulse signals. These signals are processed by a circuit to obtain the blade's rotational speed data, which is then used
to measure the fluid's flow rate.
