Threaded connection electromagnetic flowmeterPerformance characteristics and technical indicators of：
Threaded connection electromagnetic flowmeterIt is a highly intelligent and reliable flowmeter developed using advanced technology, which is easy to disassemble and assemble. 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.
Performance characteristics:
1. The measurement accuracy is not affected by changes in fluid density, viscosity, temperature, pressure, and conductivity.
2. Measurement tube *, no moving parts, no pressure loss, with low requirements for straight pipe sections.
3. Electromagnetic flow sensors can be equipped with grounding electrodes to achieve good grounding of the instrument.
4. Easy to use and disassemble, the flow sensor adopts a detachable or plug-in structure, which can facilitate maintenance and periodic calibration of indication errors.
5. The electromagnetic flow sensor adopts advanced processing technology, which enables the instrument to have good anti negative pressure capability.
6. All digital processing, strong anti-interference ability, reliable measurement, and high accuracy.
7. 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. 8. It has bidirectional flow and bidirectional total accumulation functions, and bidirectional output functions for current and frequency.
9. 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.
10. 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.
