Electromagnetic flow meters are used to measure the volumetric flow rate of conductive liquids and slurries in closed pipelines, and are suitable for departments such as chemical, power, metallurgy, petroleum, water supply and drainage, papermaking, pharmaceuticals, and food. The tested fluid must be a conductive liquid or slurry, and when its conductivity is less than 20us/cm, a dual core double shielded wire or high-frequency converter with equipotential shielding can be used. The tested fluid should not contain a lot of ferromagnetic substances or bubbles, and the appropriate pressure level, lining material, electrode material, and instrument structure should be selected according to the characteristics of the tested fluid.
1. The measurement is not affected by changes in fluid density, viscosity, temperature, pressure, and conductivity;
2. There are no obstructing flow components or pressure damage inside the measuring tube, and the requirements for straight pipe sections are relatively low;
3. The series has a nominal diameter of DN6~DN3000, and there are multiple options for sensor lining and electrode materials;
4. The converter adopts a novel excitation method, with low power consumption, stable zero point, and high accuracy;
5. The converter adopts a 16 bit high-performance microprocessor, 2X16LCD display, convenient parameter setting, and reliable programming;
6. The flowmeter is a bidirectional measurement system equipped with three integrators: forward total, reverse total, and differential total; It can display forward and reverse flow rates and has multiple outputs: current, pulse, digital communication HART;
7. The converter adopts surface mount technology (SMT) and has self checking and self diagnostic functions;
8. Rubber and polyurethane lined sensors are inherently immersive structures;
Explosion proof instruments can be used in corresponding explosion-proof places.
