Silicone meter Introduction: KH-LWGY silicone oil flow metering meter main types of flowmeters are widely used measurement of ethanol in petroleum, chemical, metallurgy, research and other fields, the control system. It uses a multi-blade rotor (turbine) the average velocity of the fluid feel, and deduced from the flow meter or total. It is generally cited by the sensor and the display device composed of two parts, can also be made integral. LW silicone meter lead and volumetric flow meter, flow meter flowmeter called three repeatability, precision best products, as one of the ten types of flow meters, and its products have been developed for multi-species, multi-series production scale. Silicone meter works: silicone meter Schematic 1. A turbine placed in the center of the pipe, both ends supported by bearings. When the fluid through the pipe, the impact of turbine blades, the turbine generates driving torque, the friction torque and the turbine customer resistance torque generated by rotation of the fluid. In a certain flow range, the viscosity of the fluid medium to a certain rotational angular velocity is proportional to the flow rate of the fluid turbine. To be detected by the rotational speed of the turbine is mounted outside the case of the sensing coil. When the turbine blade cutting charge by the housing of a long line of magnetic force magnet, can cause changes in the magnetic flux in the sensing coil. Sensing coil detects the change in magnetic flux periodic signal into the preamplifier, the signal amplification, shaping, resulting in the flow rate is proportional to the pulse signal into the unit converter circuit and flow totalizer get and display the cumulative flow value; At the same time will pulse signal into a frequency-current converter circuit converts the pulse signal into an analog current amount, and then pointed out that the instantaneous flow values. Silicone oil flowmeter structure: the generic principles silicone block diagram shown in Figure 2 the flow meter. Fluid flows into the housing from the inlet, through a pair of bearing brackets fixed to the tube central axis, a turbine mounted on bearings. Rectifying plate provided with radial upstream and downstream of the turbine in the bracket, to act as guides for the fluid, in order to avoid effect of changes of spin fluid turbine blade angle. In the top of the turbine housing is equipped with an external sensor coil, the magnetic flux change signal is received.
