High precision target flowmeter

The target flowmeter began to be used in industrial flow measurement in the 1960s. It is mainly used to solve the flow measurement of high viscosity and low Reynolds number fluid. It has experienced two development stages of pneumatic meter and electric meter. On the basis of the measurement principle of the strain gauge target flowmeter, a new type of differential sensor is adopted. The use of a new differential sensor is the key core for this new product to truly achieve high precision and high stability. It has completely changed the original strain gauge target flowmeter with large temperature drift, poor anti-overload (shock) ability, and static sealing points, etc. Various defects not only give full play to the original technical advantages of the target flowmeter, but also have the measurement accuracy comparable to that of the volumetric flowmeter, coupled with its unique anti-interference and anti-impurity performance, it can replace the traditional flowmeter The flow metering problem of measurement, especially in the working conditions of small flow, high viscosity, easy to condense and easy to block, high temperature, low temperature, strong corrosion, strong vibration and other difficult flow metering, has good adaptability. At present, it has been widely used in flow measurement in various fields such as metallurgy, petroleum, chemical industry, energy, food, and environmental protection.
