Chemical Industry Liquid Turbine Type Flow Meter Pulse Output DN25 Light Weight
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.
2. Features
- High accuracy, usually reach ±1%R,±0.5%R,or even reach ±0.2%R for high-precision type.
- Good repeatability, it can reach 0.05%-0.2% in short term, if regular calibration or online calibration can get an extremely high accuracy, so it is preferred in foreign trade.
- Pulse signal output, it is suitable for totalizer measurement and computer connection, no zero drift,strong capacity of resisting disturbance.
- High frequency signal(3-4KHz), strong signal resolution.
- Wide range, middle and big diameter can reach 1:20, and small diameter can reach 1:10.
- Compact structure, easy installation and maintenance.
3. Working Principle
How the turbine flow meter works: the fluid flows through the sensor housing, because the blades of the imperfle and flow have a certain angle, the force of the fluid makes the blades have a torque of torque, overcome the frictional torque and fluid resistance after the blade rotation, after the torque balance speed is stable, Under certain conditions, the speed is directly related to the flow rate, because the blade is magnetically conductive, it is in the magnetic field of the signal detector (composed of permanent magnetic steel and coils), the rotating blades cut the magnetic line, periodically changing the magnetic flux of the coil, Thus, both ends of the coil sense the electrical pulse signal, which is amplified by the amplifier, forming a continuous rectangular pulse wave with a certain amplitude, which can be transmitted as far away as the display meter, showing the instantaneous flow and cumulative amount of fluid.
