靶式流量计于六十年代开始应用于工业流量测量，主要用于解决高粘度、低雷诺数流体的流量测量，先后经历了气动表和电动表两大发展阶段，DX-BSL系列智能靶式流量计是在原有应变片式靶式流量计测量原理的基础上,采用了最新型电容力传感器作为测量和敏感传递元件，同时利用了现代数字智能处理技术而研制的一种新式流量计量仪表。 DX-BSL series target flowmeters have been used in industrial flow measurement since the 1960s. They are mainly used to solve the flow measurement of high viscosity and low Reynolds number fluids. They have experienced two major development stages, pneumatic and electric meters. DX-BSL The series of intelligent target type flowmeter is based on the original measuring principle of the strain gauge target type flowmeter , and adopts the latest type of capacitive force sensor as a measurement and sensitive transmission element, and a new type of technology developed by using modern digital intelligent processing technology. Flow meter.
原有的技术优势，同时又具有与容积式流量计相媲美的测量准确度，加之其特有的抗干扰、抗杂质性能，除能替代常规流量所能测量的流量计量问题，尤其在小流量、高粘度、易凝易堵、高温、低温、强腐蚀、强震动等流量计量困难的工况中具有很好的适应性。 Capacitive force sensors are the key to the true realization of high precision and high stability of this new product, which has completely changed the temperature drift of the strain gauge target flowmeter, the ability to resist overload (shock), and the existence of static sealing points. All kinds of defects not only make use of the original technical advantages of the target type flowmeter , but also have a measurement accuracy comparable to the volumetric flowmeter. In addition, its unique anti-interference and anti-impurity performance, in addition to replacing the conventional flow rate can be measured It has a good adaptability to flow measurement problems, especially in difficult flow measurement conditions such as small flow, high viscosity, easy to set and block, high temperature, low temperature, strong corrosion, and strong vibration. Has been widely used in metallurgy, petroleum, chemical, energy, food, environmental protection and other fields of flow measurement.
