The LD electromagnetic flowmeter consists of two parts: a sensor and a converter. 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. In addition to measuring the volumetric flow rate of general conductive liquids, it can also be used to measure the volumetric flow rate of strongly corrosive liquids such as strong acids and alkalis, as well as homogeneous liquid-solid two-phase suspensions such as mud, slurry, and pulp. Widely used in industrial sectors such as petroleum, chemical, metallurgical, textile, papermaking, environmental protection, food, as well as municipal management, water conservancy construction, river dredging and other fields for flow measurement.

Instrument features

1. There is no obstruction in the measuring tube, and the pressure loss is zero, making it less prone to blockage.

2. As long as the electrode and lining materials are selected reasonably, the requirements for corrosion resistance and wear resistance can be achieved.

3. The measurement results are basically independent of physical parameters such as pressure, temperature, density, viscosity, and conductivity (not less than the minimum conductivity) of the liquid, and are not affected by the environment, so the measurement accuracy is high, the work is stable, and reliable.

4. By adopting modern analog signal conversion technology and high-performance ultra large scale integrated chips, signals are isolated, filtered, amplified, and digitally processed. Accurately display measurement results.

5. It has the functions of power-off protection and over range alarm for measurement values, and can set the flow direction of the fluid inside the sensor. Therefore, the installation of the sensor is not limited by the direction of liquid flow and can achieve bidirectional flow measurement.

6. Adopting a backlit dot matrix dual row flow display, it can simultaneously display instantaneous flow, cumulative flow, and display working status, parameters, measurement units, etc.

7. The range of electromagnetic flowmeter is wide (maximum flow rate/minimum flow rate), with a normal application range of 20:1, generally 30:1 or larger.

8. The instrument configuration has multiple output functions and can be matched with computers and unit combination instruments to meet the requirements of printing, communication, and networking.
