LWGY series turbine flow sensor (hereinafter referred to as sensor) is a speed-type flow meter based on the principle of torque balance.When the fluid flows through the sensor housing, the blade of the impeller has a certain Angle with the flow direction, and the momentum of the fluid makes the blade have a rotating torque. After overcoming the friction torque and fluid resistance, the blade rotates, and the rotating speed is stable after the torque is balanced.Under certain conditions, the rotation speed is proportional to the flow rate. Since the blade has magnetic conductivity, it is in the magnetic field of the signal detector (composed of permanent magnetic steel and coil). The rotating blade cuts the magnetic field lines and periodically changes the magnetic flux of the coil, so that the two ends of the coil can sense the electric pulse signal.The signal is amplified and shaped by the amplifier to form a continuous rectangular pulse wave with a certain amplitude, which can be transmitted to the display instrument to display the instantaneous flow or total 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, and the flow equation is:
Q=3600*f/k
In the formula:
f--pulse frequency [Hz]
k--the meter factor of the sensor [1/], given by the checklist.
Q-- instantaneous flow rate of fluid (under working condition) [/h]
3600--Second conversion coefficient
The instrument coefficient of each sensor is filled in by the manufacturer in the verification certificate, and the value of k is set in the supporting display instrument to show the instantaneous flow and cumulative total.
It is suitable for measuring liquid in closed pipe which has no corrosive effect with stainless steel , corundum and hard alloy and has no impurities such as fiber and particle. It is widely used in petroleum, chemical, metallurgy, water supply, papermaking and other industries. It is an ideal meter for flow measurement and energy saving.Can measure pure water, again incoming water, pure water, medicine dregs, milk, soybean oil, edible oil, diesel oil, lubricating oil, diesel oil, aviation oil.
