High voltage electromagnetic flowmeter 1

1、 Overview

Electromagnetic flow meters can only measure conductive liquids and have requirements for the temperature of the liquid, which cannot exceed 160 degrees It is generally used to measure corrosive liquids such as domestic water, sewage, mud, lime, etc. It cannot measure organic solutions and oils Due to its high measurement accuracy, easy operation, long service life, and stable performance, electromagnetic flow meters are widely used Measure non corrosive liquids at temperatures below 80 degrees Celsius, typically using rubber liners For corrosive media, use F4 lining Choosing different liners and electrodes for different media is necessary to ensure the long-term stable operation of the electromagnetic flowmeter!

The BY-LDE series high-pressure electromagnetic flowmeter produced by Boyuan Instrument is composed of a high-pressure electromagnetic flow sensor and an intelligent converter produced using proprietary technology and special processes. It is specifically used for measuring the volume flow of conductive liquid or liquid-solid two-phase media such as mud, cement slurry, and high-pressure water injection under high-pressure conditions in geological, petroleum exploration, and oilfield systems.

2、 Characteristics of High Voltage Electromagnetic Flow Meter

·The measurement is not affected by changes in fluid density, viscosity, temperature, pressure, and conductivity.

·The measuring tube has unobstructed flow components, no pressure loss, and low requirements for straight pipe sections.

·The sensor can be equipped with a grounding electrode to achieve good grounding of the instrument.

·The sensor adopts processing technology to make the instrument have good anti negative pressure ability.

·The converter adopts a liquid crystal backlight display, which makes it easy to read under reflected sunlight or in a dark room.

·The installation of a 90 ° rotating display screen on the pipe improves the visibility of the integrated flowmeter compared to the standard model.

·By using infrared touch buttons to set parameters, it is possible to safely set them without opening the cover of the converter in harsh environments.

·The converter has self diagnostic alarm output, empty load detection alarm output, flow upper and lower limit alarm output, and two pole flow value alarm output

Waiting for functions.

·Not only can it be used for general process detection, but it is also suitable for measuring slurry, pulp, and paste liquids.

·The high-pressure electromagnetic flowmeter sensor is manufactured using patented technology and is specifically used in industries such as petroleum and chemical.
