what's the flow meter for acid,alkali,salt solution liquid ?

Acid alkali salt solution flow meter consists of two parts consisting of sensor and converter is based on Faraday's law of electromagnetic induction to work, used to measure the conductivity of greater than 5uS / cm conductive liquid volume flow, is an electrically conductive medium volume flow measurement sensors meter. The main components of the sensor are: measuring tube, electrodes, excitation coil, core and yoke housing. Mainly used to measure conductivity in closed conduits and uniform liquid and liquid mud, pulp, pulp and other solid volume measuring two-phase liquid suspension. Including acids, alkalis and other corrosive liquids. Electromagnetic flowmeters are widely used in petroleum, chemical, metallurgy, textile, food, pharmaceutical, paper and other industries as well as environmental protection, municipal administration, water conservancy construction,

What's the principle of electromagnetic flow meter ?
Electromagnetic flowmeter flow measurement is based on Faraday's law of electromagnetic induction flowmeter. Advantages electromagnetic flowmeter pressure loss is extremely small, large measurable flow range. The ratio of maximum flow and minimum flow rate is generally 20: 1 or more, applicable to a wide range of industrial pipe diameter, up to 3m, output signal and the measured flow rate is linear, high accuracy, measure the conductivity s / cm acid , alkali, salt solution, water, sewage, corrosive liquids and slurries of fluid flow. But it can not gas, steam and pure water flow measurement. When the conductor for cutting magnetic field lines move in a magnetic field, the conductor will produce EMF, EMF size and the effective length of the conductor and the conductor in a magnetic field perpendicular to the magnetic field as a speed proportional to the direction of motion in the magnetic field. When Similarly, the conductive fluid in a magnetic field perpendicular to the direction of flow and cutting magnetic induction power line, will produce EMF on the pipeline on both sides of the electrode


What's the advantage of electromagnetic flow meter ?
1) Measurement of electromagnetic flowmeter is not affected by fluid density, viscosity, temperature, pressure and electrical conductivity changes and other factors;
2) measuring tube unimpeded flow of parts, no pressure loss, lower section of the straight pipe requirements;
3) electromagnetic flowmeter nominal diameter of DN10 ~ DN2200. Sensor lining and electrode materials have a variety of options;
4) converter uses a novel excitation mode, low power consumption, zero stability, high accuracy. Flow range of up to 1500:
5) The converter can be composed of a body or a separate type of sensor;
6) The converter uses 16-bit high-performance microprocessors, 2x16LCD display, convenient parameter setting, programming and reliable;
7) The electromagnetic flowmeter is bidirectional measurement system, built-in three Totalizer: forward total, reverse total and the total amount of the difference; can be displayed. Zhuang, regurgitation, and a variety of output: current, pulse, digital communications, HART;
8) converter using surface mount technology (SMT), a self-test and self-diagnostic function;
