LD flowmeter applications and features

LD electromagnetic flowmeter consists of two parts: sensor and converter. It works based on Faraday's law of electromagnetic induction and is used to measure the volume flow of conductive liquids with conductivity greater than 5 μS/cm. It is an inductive instrument that measures the volume flow of conductive media. In addition to measuring the volume flow of general conductive liquids, it can also be used to measure the volume flow of highly corrosive liquids such as strong acids and strong alkali, as well as uniform liquid-solid two-phase suspension liquids such as mud, pulp, and paper pulp. Shanghai Automation Instrument No. 9 Factory electromagnetic flowmeters are widely used in flow measurement in petroleum, chemical industry, metallurgy, textile, papermaking, environmental protection, food and other industrial sectors as well as municipal management, water conservancy construction, river dredging and other fields.

Instrument features

1. There are no flow obstructions in the measuring tube of the electromagnetic flowmeter, the pressure loss is zero, and it is not easy to block.

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

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

4. Use modern analog signal conversion technology and high-performance large-scale integrated chips to isolate, filter, amplify and digitally process signals. Display measurement results.

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

6. It adopts a double-row flow display with backlight dot matrix, which simultaneously displays instantaneous flow and cumulative flow, and can display working status, parameters, measurement units, etc.

7. The electromagnetic flowmeter has a wide measuring range (large flow/small flow). The normal applicable range is 20:1 and generally 30:1 or greater.

8. The instrument is equipped with a variety of output functions and can be matched with computers and unit combination instruments to complete printing, communication and networking requirements.
