Kaifeng Chuangxin' Electromagnetic flow meter is composed of sensor and converter. It comes in two forms: compact-type and remote-type. The remote-type also requires a special double-layer shielded cable to connect the converter and sensor. There are seven types of electrode materials and four types of lining materials available for sensors.
The measurement principle of electromagnetic flow meter is based on Farady's electromagnetic induction law. The sensor is mainly composed of measuring tubes with isolate lining, a pair of electrodes installed by penetration of the measuring tube wall, a pair of coils and an iron core to produce a working magnetic field.
Features:
Ø Not affected by fluid density, viscosity, temperature, pressure and conductivity;
Ø No moveable parts in the measuring tube, no pressure loss, and lower requirements for straight pipe sections.
Ø Bidirectional measurement system with three built-in totalizers, forward total, reverse total and difference total;
Ø Display forward and reverse flow, multiple outputs: current, pulse, digital communication, HART;
Ø Reasonable selection materials of liner and electrode, excellent corrosion resistance and wear resistance;
Ø Excitation mode converter with low power consumption, stable zero point and high accuracy.
Ø Using surface mount technology (SMT), with self-test and self-diagnosis alarm output, empty load detection alarm output, flow rate upper and lower limit alarm output, batch control and other functions.
Ø Through infrared touch buttons, parameter setting is convenient and programming is reliable.

Electrode Material Application Molybdenum-containing stainless steel (0Cr18N12Mo2Ti) Applicable to industrial/municipal water, wastewater and low corrosive mediums.
Widely used in petroleum, chemical industries. Hastelloy B Strong resistance to hydrochloric acids below the boiling point.
Resist against oxidable acids, alkali and non-oxidable salts. For instance, vitriol, phosphate, hydrofluoric acids, and organic
acids. Hastelloy C Exceptional resistance to strong solutions of oxidizing salts and acids.
For example, Fe+++, Cu++, Nitric acids, mixed acids Titanium Titanium can withstand corrosive mediums such as seawater, chloride salt solutions, hypochlorite salts, oxidable acids(including
fuming nitric acids), organic acids, and alkali.
Not resistant to high purity reducing acids such as sulphuric acids, hydrochloric acids. Tantalum Highly resistant to corrosive mediums.
Applicable to all chemical mediums except Hydrofluoric Acids, Oleum and Alkali. Platinum-iridium Applicable to all chemical mediums except for Ammonium salts and Fortis.
