1. Introduction
LWGYML series intelligent liquid turbine Flowmeter is a new type of intelligent instrument with the integration of turbine flow sensor and display accumulation developed by advanced ultra-low power consumption single-chip microcomputer technology. it has the advantages of compact mechanism, intuitive and clear reading, high reliability, no interference from external power supply, anti-lightning strike, low cost and so on.
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
3. Working Principle
Working principle of turbine flowmeter: the fluid flows through the sensor housing. Because the impeller blades have a certain angle with the flow direction, the impulse force of the fluid makes the blades have a rotating moment. After overcoming the friction moment and fluid resistance, the blades rotate. After the moment is balanced, the rotating speed is stable. Under certain conditions, the rotating speed is directly proportional to the flow velocity. Because the blades have magnetic conductivity, they are in the magnetic field of the signal detector (composed of permanent magnetic steel and coils), and the rotating blades cut magnetic lines. The magnetic flux of the coil is changed periodically, so that the electric pulse signal is 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 accumulated amount of fluid.
