3、 Introduction to LWGY type technology of PTFE turbine flowmeter for chemical wastewater:

The working principle of LWGY turbine flowmeter is that the fluid flows through the sensor housing. Due to the angle between the blades of the impeller and the flow direction, the impulse of the fluid 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 rate. Due to the magnetic conductivity of the blades, they are in the magnetic field of the signal detector (composed of permanent magnet and coil). 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 the display instrument remotely to display the instantaneous flow rate and cumulative amount of the fluid. The sentence is:. Within a certain flow range, the pulse frequency f is proportional to the instantaneous flow rate Q of the fluid flowing through the sensor, and the flow equation is Q=3600 × f/k

Where:

F - Pulse frequency [Hz];

K - the instrument coefficient of the sensor [1/m], given by the calibration sheet. If using [1/L] as the unit, Q=3.6 × f/k

Q - instantaneous flow rate of fluid (under working conditions) [m/h];

3600- Conversion factor.

The instrument coefficient of each turbine flowmeter is filled in the calibration certificate by the manufacturer, and the k value is set in the matching display instrument to display the instantaneous flow rate and cumulative total amount.
