Product Details

Brief introduction:

The XRLDG intelligent integrated electromagnetic flowmeter consists of two parts: sensors and converters. It works based on Faraday's law of electromagnetic induction and is used to measure the volumetric flow rate of conductive liquids with a conductivity greater than 5 μ S/cm. It is an inductive instrument for measuring the volumetric flow rate of conductive media. The intelligent integrated electromagnetic flowmeter can not only measure the volumetric flow rate of general conductive liquids, but also be used to measure the volumetric flow rate of strong corrosive liquids such as strong acids and alkalis, as well as uniform liquid-solid two-phase suspensions such as mud, slurry, and pulp.

Overview of Intelligent Integrated Electromagnetic Flow Meter

　　XRLDGThe intelligent integrated electromagnetic flowmeter consists of two parts: sensors and converters. It works based on Faraday's law of electromagnetic induction and is used to measure the volumetric flow rate of conductive liquids with a conductivity greater than 5 μ S/cm. It is an inductive instrument for measuring the volumetric flow rate of conductive media. The intelligent integrated electromagnetic flowmeter can not only measure the volumetric flow rate of general conductive liquids, but also be used to measure the volumetric flow rate of strong corrosive liquids such as strong acids and alkalis, as well as uniform liquid-solid two-phase suspensions such as mud, slurry, and pulp.

Due to the many advantages of XRLDG intelligent integrated electromagnetic flowmeter, it is widely used in industrial sectors such as petroleum, chemical, synthetic fiber, metallurgy, textile, papermaking, sugar production, water supply and drainage, environmental protection, food and municipal management, water conservancy construction, river dredging and other fields for flow measurement.

Characteristics of intelligent integrated electromagnetic flowmeter

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.

● Selection of electrode materials
The material of the electrode should be selected based on the corrosiveness of the fluid being tested. Please refer to the relevant manual. For special fluids, a corrosiveness test should be conducted

material	code name	corrosion resistance
316L stainless steel	V	1. Suitable for neutral solutions such as industrial and domestic water, raw water and well water, urban sewage, etc 2. Weakly corrosive acid, alkali, salt media such as carbonic acid, acetic acid, etc
HastelloyC	HC	1.
