Intelligent target type flowmeter uses the latest capacitive force sensor as the measurement and sensitive transmission element
2012-3-8 14:07:54

采用了最新型电容式力传感器作为测量和敏感传递元件,同时应用了最新数字技术和微电子技术,是一款适用于高粘度、低雷诺数及含有微小颗粒的流体和气体测量的智能流量计。 ZNB target type intelligent flowmeter uses the latest capacitive force sensor as a measurement and sensitive transmission element, and applies the latest digital technology and microelectronics technology. It is a high viscosity, low Reynolds number and fluid containing micro particles and Smart flow meter for 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 not only has the characteristics of traditional orifice plates, vortex street and other flowmeters without moving parts, but also has a measurement accuracy comparable to the volumetric flowmeter, plus its unique anti-interference and anti-impurity performance. It can replace conventional flowmeters and conventional fluid flow measurement, especially in high-viscosity, easy-to-clog, high-temperature, high-pressure, strong corrosion, and other difficult-to-measure flow conditions. It has a good application value, and has been widely used in steel, petroleum Flow measurement in various fields such as natural gas, electric power, papermaking, chemical industry, energy, food, environmental protection and other fields.
Scope of application ◆ Suitable for various nominal diameters, from DN15 to DN2000mm to larger;
◆ Suitable for high and low temperature media: -50 ℃ ~ + 260 ℃;
◆ Suitable for low, medium and high pressure working conditions: from 0 to 42 MPa (gauge pressure);
特点 Features of Intelligent Target Flowmeter
1.No moving parts, reduced sealing surface, greatly reducing leakage rate, easy installation and routine maintenance;
2. Wide measurement range, the maximum measurement range can reach 20: 1 (liquid) or 10: 1 (gas);
3. Accurate measurement and high precision, flange type can reach 0.2% (liquid) or 0.5% (gas);
4, extremely high sensitivity, can measure ultra-small flow, which can measure low flow rate of 0.08m / s, electromagnetic flowmeter 0.5m / s;
5, good repeatability, generally 0.05 ~ 0.08%, with optional small signal removal, non-linear correction, filtering time can be selected;
6.The pressure loss is small, the small diameter is only about 1/2 △ P of the standard orifice plate; the pressure loss above the DN100 diameter has begun to decrease significantly;
7, convenient calibration, in addition to the standard device verification, you can also use the dry calibration method, that is, using the weight hanging method, one-button operation can complete the calibration;
8. The flow blocking range can be changed according to actual needs. The online removable plug-in structure can realize non-stop production and continuous flow repair or replacement.
9, low-power battery on-site display, can directly read the displayed value online, the display can simultaneously read the instantaneous flow cumulative flow and percentage bar graph, and can switch to display the compensation temperature and compensation pressure indication;
10. Strong anti-interference and anti-impurity capabilities, multiple output forms, can transmit various parameters remotely, no need to mix heat.
The intelligent target type 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 fluids. It has experienced two development stages of pneumatic meters and electric meters. ZD -BSL series intelligent targets Flowmeter is a new type of flowmeter based on the original strain gauge target flowmeter measurement principle, using the latest capacitive force sensor as a measuring and sensitive transmission element, and using modern digital intelligent processing technology. . 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 take advantage of the original technical advantages of the intelligent target type flowmeter , but also have a measurement accuracy comparable to that of the volumetric flowmeter. In addition, its unique anti-interference and anti-impurity performance can replace conventional flow capacity. The measurement flow measurement problem has good adaptability especially in the 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.
