It is a high viscosity, low Reynolds number and micro particle containing Intelligent flow meter for fluid and gas measurement. The use of capacitive force sensors is the key to the product's true high accuracy and stability. The target type intelligent flowmeter has the characteristics of no moving parts such as traditional orifice plates and vortex flowmeters, and has measurement accuracy comparable to that of volumetric flowmeters, plus its unique anti-interference and anti-impurity properties. It can replace conventional flow meters and conventional fluid flow measurement, and has very good application value, especially in difficult working conditions such as high viscosity, easy jamming, high temperature, high pressure, and strong corrosion. The new generation of intelligent target type flowmeter integrates flow, temperature and pressure detection functions. It adopts advanced single-chip microcomputer technology and capacitive force sensor. The product has no moving parts, has strong anti-vibration, impurities, and interference ability. It has simple operation and installation. Easy, maintenance-free, fault self-test, low running cost and other features. It has been widely used in the measurement of the following media, which has solved the difficult flow measurement in the industry for many years. Such as semi-water gas, coke oven gas measurement, heavy oil, residual oil measurement, asphalt, liquid paraffin, toluene, sulfuric acid, natural gas, methane chloride, flue gas, chlorine gas, sewage, purified water, and other special media. Working principle When the medium flows in the measuring tube, due to its own kinetic energy and pressure difference between the target plate, the force on the target plate is generated, causing the target plate to generate a small amount of displacement, and the magnitude of its force is the square of the flow velocity of the medium It is proportional to the force received by the target plate and transmitted through the target rod to cause a small change in the elastic body of the sensor, thereby breaking the bridge balance composed of chip capacitance. Generate a voltage signal corresponding to the force of the flow on the target: The flow is proportional to the square of the voltage generated by the bridge due to the characteristics of the flow of the fluid.
