Product Description
QFM404 liquid turbine flow meters Turbine flow sensor and receiving from the electrical pulse signal composed of
intelligent display devices. Used to measure the low-viscosity liquids in closed conduits instantaneous
volume flow and volume in petroleum, chemical industry, metallurgy, aviation and scientific research departments have been widely used.
QFM liquid turbine flow sensor from the turbine body and pre-amplifier. Display Instrument developed and manufactured by our company using SMIT-E-Y01.Intelligent Flow Totalize. The flow meter JG198-94 tests the implementation of national regulations and Q/12KF3989-2001 XFT Series Turbine Flow meter enterprise standard.
Sensor is based on the torque balance theory, when the liquid flows through the sensor, in the special structure of rectifiers (D1) to be rectified under the action and speed, due to turbine blades and fluid flow into a certain angle, in accelerating the fluid under the action of the impeller (D2) produce rotational torque to overcome friction torque and fluid resistance, the turbine begins to rotate, to a certain flow range,
the turbine's rotational speed and flow rate is proportional to volume flow. Impeller rotating-cut magnetic lines, periodically changing the coil (D3) in the magnetic flux, so that both ends of the coil sensor and the volume of fluid flow is proportional to the pulse signal, the signal after amplification, filtering, reconstructive surgery into the Flow Totalizer (A) to computing processing, and display on the LCD on the spot.
