Liquid or Gas Industrial Flow Meter Turbine Flowmeter
1. Introduction
LWGYML series turbine flow meter is a new generation kind of flow meter that absorbs the advanced technologies of flow meter at home and abroad. It has been optimized and designed to have so many characteristics, such as simple structure, light weight, high precision, good repeatability,easy installation and usage.
It is widely used in the sealed pipelines which doesn’t have corrosion function on SS 1Cr18Ni9Ti, 2Cr13, corundum Al2O3 and cemented carbide and have no fiber, particle and so on. The liquid should be less than 5*10-6m2/s with viscosity under working temperature, if the viscosity of the liquid is more than 5*10-6m2/s, then the flow meter can be used after calibration. If it is equipped with other display devices with special functions, it can also do quantity control, excessive alarm and so on. It is really perfect in flow measurement and energy
conservation.

4. Working Principle
Working principle of turbine flowmeter: Fluid flowing through the sensor shell, as a result of the impeller blade and flow to a certain point of view, the impact of fluid blade with rotational torque, to overcome the friction torque and fluid resistance, blade rotation speed stability after the moment balance, under certain conditions, the speed is proportional to the velocity of flow, because there are magnetic conductivity blade, it is in the signal detector (consists of permanent magnets and coils) magnetic field, rotating blade cutting lines, periodically changing coil magnetic flux, so that the coil ends induction electrical pulse signal, the signal after amplifier amplification plastic, form a certain amplitude of continuous rectangular pulse wave, It can be transmitted to the display instrument, showing the instantaneous flow rate and accumulative amount of fluid.
