Flow meter
DXLG electromagnetic flowmeter

DXLG series electromagnetic flowmeter


Overview: LD electromagnetic flowmeter consists of two parts: sensor and converter. It is based on Faraday's law of electromagnetic induction. It is used to measure the volumetric flow of conductive liquids with a conductivity greater than 5uS / cm. It is an inductive meter that measures the volumetric flow of conductive media. In addition to measuring the volumetric flow of general conductive liquids, it also It can be used to measure the volumetric flow rate of strong corrosive liquids such as strong acids and alkalis, and uniform liquid-solid two-phase suspension liquids such as mud, ore pulp, and pulp. Widely used in petroleum, metallurgy, chemical industry, papermaking, environmental protection, light textile, food and other industrial sectors and municipal management, water conservancy construction, river dredging and other fields.


Features of the instrument: 1 There is no obstruction in the measuring tube, the pressure loss is zero, and it is not easy to block.
2As long as the electrodes and lining materials are reasonably selected, the requirements of 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 electrical conductivity (not less than the minimum electrical conductivity) and are not affected by the environment. Therefore, the measurement accuracy is high, and the work is stable and reliable.
4 Using modern analog signal conversion technology and high-performance ultra-large-scale integrated chips, the signal is isolated, filtered, amplified and digitally processed. Accurate display of measurement results.
5 It has the function of measuring value power failure protection and process alarm, which can set the flow direction of the fluid in the sensor, so the sensor installation is not restricted by the direction of liquid flow, and it can realize bidirectional flow measurement.
6 Adopting dot-matrix dual-row flow display with backlight, which can display instantaneous flow and accumulated flow, and can display the actual working status, parameters, and measurement units.
7 The range of the electromagnetic flowmeter is wide (maximum flow rate / minimum flow rate), and the normal application range is 20: 1, generally 30: 1 or more.

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

Selection of electrode materials and materials in the process: 1 Selection of electrode materials: The user is responsible for selecting the general medium according to the corrosiveness of the measured medium. You can check the relevant anti-corrosion manuals, select the electrode materials, and the composition of mixed acids The medium should be used for hanging experiments.


2 Selection of lining material: It should be selected according to the corrosivity, abrasion and temperature of the measured medium. Chloroprene rubber can withstand the general weak acid and alkali corrosion, the temperature is 65 ℃, and the neoprene has abrasion resistance. Polytetrafluoroethylene is almost resistant to strong acids other than hot phosphoric acid and alkali corrosion. The medium temperature can reach 180 ° C but it is not resistant to wear.
