Target flowmeter in the sixties began to be used industrial flow measurement, mainly used to solve high-viscosity, low Reynolds number fluid flow measurement, has experienced a pneumatic table and electric meter two stages of development, NBL Series Intelligent Target Flowmeter is based on the original target flowmeter strain gauge measurement principle based on the use of the latest capacitive force sensor as a measurement and sensitive transfer element, while the intelligent use of modern digital processing techniques and developed a new flow measurement instruments using capacitive force sensor is that the new product truly high precision and high stability of the key core, completely changed the original target flowmeter drift strain, anti-overload (shock) is poor, there are limitations such as static sealing point, not only played an original target flowmeter technology, but also has a measurement accuracy of volumetric flowmeter comparable, coupled with its unique anti-jamming, anti-impurity performance, can replace conventional flow metering flow can be measured in addition to problem, particularly in low flow, high viscosity, easy pour easy to block, high temperature, highly corrosive, strong vibration measurement flow difficult conditions has good adaptability. Has been widely used in the flow measurement metallurgy, petroleum, chemical, energy, food, environmental protection and other fields.
