Product Description
CKAS-FLYW990 series liquid turbine flowmeter is a precision flow measuring instrument composed of a turbine flow sensor and a display instrument. It belongs to the speed type flow meter. It is manufactured with foreign advanced technology and is one of the ideal flowmeters for liquid flow measurement. CKAS-FLYW990 series Liquid turbine flowmeters are widely used in petroleum, chemical industry, metallurgy, water supply, papermaking, environmental protection, food, medicine and other fields. They are suitable for flow measurement of liquids with no impurities, no strong corrosion and low viscosity. The quantitative controller is used together to realize functions such as over-quantity alarm or automatic quantitative control.
CKAS-FLYW990 series liquid turbine flowmeter adopts explosion-proof design standard as a whole, and explosion-proof or non-explosion-proof products are optional. The explosion-proof products have the explosion-proof certificate issued by the state, and the explosion-proof mark: Ex dCT6 Gb, are widely used in industrial sites that require explosion-proof
Features

working principle
When the measured fluid flows through the sensor, because the blade of the impeller has a certain angle with the flow direction, the impulsive force of the fluid causes the blade to have a rotational moment. After overcoming the frictional moment and fluid resistance, the blade rotates. After the torque is balanced, the speed is stable. Under certain conditions Next, the rotation speed is proportional to the flow velocity. Because the blade has magnetic permeability, it is in the magnetic field of the signal detector (composed of permanent magnet steel and coil). The rotating blade cuts the magnetic force line and periodically changes the magnetic flux of the coil, so that the coil The electric pulse signal is induced at both ends, and 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 remotely to display the instantaneous flow or cumulative flow of the fluid
Within a certain flow range, the pulse frequency f is proportional to the instantaneous flow Q of the fluid flowing through the sensor, and the flow equation is:
The instrument coefficient of each sensor is filled in the verification certificate by the manufacturer, and the k value is set in the supporting display instrument to display the instantaneous flow and cumulative total.
