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. ，集流量，温度，压力检测功能于一体，采用先进的单片机技术和电容式力传感器，产品无可动部件，抗振动，杂质，干扰能力强，具有操作简单，安装容易，免维护，故障自检，运行费用低等一系列特点。 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. The target type intelligent flowmeter has been widely used in flow measurement in various fields such as steel, petroleum, natural gas, electric power, papermaking, chemical industry, energy, food, environmental protection and other fields.
在60、70年代国内仪器仪表厂无法解决的高粘度、多杂质、小颗粒、低雷诺数流体的测量的情况下而发展的一款流量计。 The traditional target type intelligent flowmeter is a flowmeter developed under the conditions of high viscosity, multiple impurities, small particles, and low Reynolds number fluids that cannot be solved by domestic instrument and meter factories in the 1960s and 1970s. Since the 1990s, China's modernization has been advancing by leaps and bounds, with particular emphasis on the petroleum, chemical, and energy industries. It is urgent to transform the traditional target flowmeter to meet market demand. For this reason, in 1996, the technicians of Quanzhou Rixin Flow Instrumentation Co., Ltd. independently researched and developed the SBL type digital display target flowmeter combining traditional essence and modern technology after repeated experiments, which overcomes the shortcomings of the traditional target flowmeter. With digital display, remote transmission and communication output functions, it has become a popular intelligent target flow meter. Obtained a national patent in 1997 with the patent number: ZL00201624.9, and was included in the special plan for technical innovation of the State Quality and Technical Supervision Bureau and the key free support project of the Innovation Fund of the Ministry of Science and Technology. In 2004, the project was identified as advanced internationally and domestically leading by scientific and technological achievements made up of many traffic experts and scholars.
Dongxiang Instrument Factory Flow Co., Ltd. uses international advanced technology and independent innovation of domestic real-time liquid and gas flow standard domestic first-class testing devices, and has been designated as a gas flow verification station by the Provincial Bureau of Quality and Technical Supervision and the Fujian Provincial Institute of Metrology. Public standards not only provide guarantee for product quality, but also create conditions for continuous technological research and development. In 2011, under the situation of rising raw materials, the development of Instrument and Instrument Factory Co., Ltd. enterprises has reached an impasse. We chose to pay more attention to the development of the brand with integrity, and explain the integrity with the brand, so as to lead Nisshin ’s concept of “green products and conscience”, and set a brand example of flow instruments.
