Aumeascon AM-LTF Liquid Turbine Flow Meter

AM-LTF  Liquid Turbine Flow Meter

Aumeascon AM-LTF turbine flow meter consists of turbine flow sensor and display instrument and it is made by us using foreign state-of-the-art technologies, which is an ideal gauge for measuring of liquid flow.The flow meter is characterized by simple structure, high precision and easy installation and repair.It is applicable in closed pipes to measure flow of liquid which will not erode stainless steel (1Cr18Ni9Ti), 2Cr13, Al2O3 and hard alloy and is free of impurities such as fiber and granules. if this product is used in association with display instruments with special functions, it can be used for purpose of automatic definite quantity control and alarming in case of excessive amount.

 

Working principle

When liquid flows through the sensor, the impulse of fluid will provide the blade with a rotation moment as there is an angle between the blade of impeller and the flow direction. the blade will rotate as the friction moment and the fluid resistance are overcome and it will reach a stable speed when the moments are at balance. under certain conditions, the rotation speed of blade will be in direct proportion to the flow velocity. due to the magnetic conductivity of blade, when located in the magnetic field generated by signal detector (made of permanent magnet steel and coils), the rotating blade will cut the magnetic lines and periodically change the flux through the coil, thereby inducing electrical impulse signals at both ends of the coil. the induced signals, after amplified and rectified by amplifier, will form a continuous rectangular impulse wave with certain amplitude which may be remotely transmitted to display instrument indicating the instant flow and the cumulative flow of fluid. within a certain range of flow, the impulse frequency is in direct proportion to the instant flow of fluid flowing through the sensor, which is shown in the equation below:

 

f	Impulse frequency [Hz].
k	Instrument factor of sensor [1/m3], which is given by checklist. [1/L] is used as the unit, the equation will be.
Q	Instant flow of liquid (in operation) [m3/h].
3600	Conversion factor.

Instrument factor of each turbine flow sensor will be filled out in verification certificate by Aumeascon. the instant flow and cumulative flow will be displayed when the value of k is loaded into associated display instrument.
