What is the anticorrosive electromagnetic flowmeter
Anticorrosive electromagnetic flowmeter is what, full intelligent anticorrosive electromagnetic flowmeter USES the world's latest technology application.By using constant current low-frequency rectangular wave or double-frequency rectangular wave excitation, it has the advantage of rectangular wave electromagnetic field and gets rid of the defect of sine wave electromagnetic field.It can eliminate the deviation caused by power supply voltage fluctuation, power supply frequency change and excitation electromagnetic coil impedance change.It has excellent zero point stability and is free from fluid noise.Thus has the high stability, the high reliability characteristic.
Measurement principle is based on Faraday's law of electromagnetic induction, the entire intelligent anticorrosive electromagnetic flowmeter consists of controller and converter, controller installed in the way of tube, the converter can be combined with controller connected together is called a shape electromagnetic flowmeter, the converter is installed within 100 meters of within 30 meters away from the controller or occasions, separated by called shielded cable connection type between electromagnetic flowmeter.
The key components of the controller are: measuring tube, electrode, excitation electromagnetic coil, core and yoke housing.Mainly used for measuring volume flow of conductive liquid and slurry in closed pipeline.Such as water, sewage, mud, paper paddle, various acid, alkali, salt solution, food slurry, widely used in petroleum, chemical plant, metallurgy, textile, food, pharmaceutical, paper industry, environmental protection, municipal management, water conservancy construction and other fields.
What is the anticorrosive electromagnetic flowmeter
Product features:
1. The converter adopts 16-bit high-performance microcontroller, 2x16LCD display, convenient parameter setting and reliable program writing;
2. No flow obstructing parts in the pipe, no pressure loss, low requirements for straight pipe segment;
3. Series nominal sizes DN15 ~ DN3000.Controller lining and electrode materials are available in a variety of options;
4. The converter adopts novel excitation method, low power consumption, zero point stability and high accuracy.The traffic category can reach 1500:1
5. The converter can be integrated or separated from the controller;
6. The flowmeter is a two-way detection system with three integrators: forward total output, reverse total output and difference total output;It can display.Zhuang, reverse flow, and with a variety of output: current, pulse, digital communication, HART;
7. The converter adopts surface mounting technology and SMT, with self-test and self-diagnosis functions;
8. The measurement is not affected by changes in fluid density, viscosity, temperature, pressure and conductivity
Porcelain city Shanghai instruments co., LTD., the introduction of Germany Siemens numerical control processing center, make the tiny flowmeter is greatly increased, actually has reached world leading level, such as OVAL LSF40, many clients in Japan and the customer to know LSF40 flow range in 0.7 ~ 50 l/H, and porcelain xian CX - M5 - AL can achieve 0.3 ~ 60 l/H, the same 0.5% FS precision, another porcelain city gear is SS316L is qualitative, OVAL gear is plastic.
