Overview of High Voltage Electromagnetic Flowmeters
The CH-LEG series Chinese high-pressure electromagnetic flowmeter is a highly intelligent and reliable flowmeter developed using international advanced technology. It can be used not only for general process detection, but also for measuring slurry, pulp and paste liquids. It is widely used in industries such as petroleum, chemical, steel, food, electricity, papermaking, water conservancy and drainage, water administration and water resources.
2、 Characteristics of High Voltage Electromagnetic Flow Meter
The measurement accuracy is not affected by changes in fluid density, viscosity, temperature, pressure, and conductivity.
The measuring tube has no obstruction, no moving parts, and no pressure damage, and the requirements for the straight pipe section are relatively low.
Electromagnetic flow sensors can be equipped with grounding electrodes to achieve good grounding of the instrument.
The electromagnetic flow sensor adopts advanced processing technology, which enables the instrument to have good anti negative pressure capability.
All digital processing, strong anti-interference ability, reliable measurement, and high accuracy.
High definition backlit LCD display, full Chinese character menu operation, easy to use, simple to operate, can read clearly even in strong light at night.
It has bidirectional flow and bidirectional total accumulation functions, and bidirectional output functions for current and frequency.
The instrument system has high measurement accuracy and a wide range of applications. It is not suitable for measuring sewage, cement slurry, slurry, etc., but can also be used for measuring the flow rate of strong acid and alkali liquids.
The converter has powerful output functions: it not only has 4-20mA and pulse output, but also digital communication such as RS485 or RS232, HART, and GPRS wireless data remote 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.
