Split electromagnetic flowmeter overview
CH-LEFT series Chinese split electromagnetic flowmeter is the use of international advanced technology developed a highly intelligent, highly reliable flowmeter, not only for general process detection, but also for pulp, pulp and paste liquid measurement, widely used in petroleum, chemical, iron and steel, food, electricity, paper, water supply and drainage, water and water resources and other industries.
Second, the split electromagnetic flowmeter features
Measurement accuracy is not affected by changes in fluid density, viscosity, temperature, pressure and conductivity.
Measuring tube without obstruction, no moving parts, no pressure loss, straight pipe section requirements are low.
Electromagnetic flow sensor can be with grounding electrode to realize good grounding of the instrument.
Electromagnetic flow sensor adopts advanced processing technology, so that the instrument has good anti-negative pressure ability.
Full digital volume processing, strong anti-interference ability, reliable measurement, high precision.
High-definition backlit LCD display, full Chinese character menu operation, easy to use, easy to operate, in the bright light under the goods at night can read clearly.
With bi-directional flow, bi-directional total amount of totalization function, current, frequency with bi-directional output function.
Instrumentation system with high measurement accuracy, wide range of use, not can be used for sewage, cement slurry mining slurry liquid, etc., but also for strong acid, strong alkali liquid flow measurement.
Converter output function is powerful: not only with 4-20mA, pulse output, but also with RS485 or RS232, HART and other digital communication and GPRS wireless data transmission.

| vantage | drawbacks | |
| 1 | There are no moving parts and no throttling parts in the measuring tube to impede the flow of fluid, which does not cause any additional pressure loss when the fluid passes through the meter. | It can only measure the liquid flow of conductive media, not the flow of non-conductive media |
| 2 | Electromagnetic flow meters can be used to measure the flow of other electrically conductive liquids after calibration with water only. | Cannot be used to measure gases, vapors, or liquids containing large quantities of gases. |
| 3 | Their range ratios can be up to 20:1, and some even up to 100:1 range ratios. | The medium in the pipe must be full, and cannot be measured out of a full pipe. |
| 4 | No mechanical inertia, sensitive response, can measure instantaneous pulsating flow, positive and negative direction of flow | Can only be measured above DN10 pipe, not applicable to small diameter |
| 5 | Measure the flow of corrosive media, spoiled media and suspended liquid-solid two-phase flow. | Cannot measure hydrofluoric acid media |
1, should be installed in the horizontal pipeline lower and vertically upward, avoid installation in the pipeline *** point and vertical downward;
2、It should be installed at the rising place on the pipeline;
3, in the open discharge pipeline installation, should be installed in the lower part of the pipeline;
4、If the pipeline drop is more than 5m, an exhaust valve should be installed downstream of the sensor;
5, should be installed downstream of the sensor control valves and shut-off valves, and should not be installed in the sensor upstream;
6, the sensor *** can not be installed in the pump inlet and outlet, should be installed in the pump outlet.
