LDG domestic electromagnetic flowmeter

Description :

　　LDG domestic electromagnetic flowmeter

　　1. Overview:

　　This product can measure the flow rate of dirty media, corrosive media, and suspended liquid-solid two-phase flow. This is because there are no flow obstructing components inside the instrument measuring tube, and only the inner lining and electrodes of the measuring tube are in contact with the measured fluid. The material can be selected according to the properties of the measured fluid. For example, using polytetrafluoroethylene or polytetrafluoroethylene as lining can measure various corrosive media such as acids, alkalis, salts, etc; The use of wear-resistant rubber as an inner lining is particularly suitable for measuring liquid-solid two-phase flows such as slurry and cement slurry with solid particles and high wear, as well as various suspended liquids such as fibrous liquids and pulp.

　　2、 Characteristics:

　　1. The range of electromagnetic flowmeter is wide.

　　2. In addition to measuring the volumetric flow rate of general conductive liquids, electromagnetic flow meters can also be used to measure strongly corrosive liquids such as strong acids and alkalis, as well as slurries, slurries, and pulp.

　　3. A bidirectional measurement system that can measure both forward and reverse flow rates.

　　4. The measurement results of electromagnetic flowmeter are independent of physical parameters such as pressure, temperature, density, viscosity, conductivity, and are not affected by the environment.

　　5. Electromagnetic flowmeter has reliable performance, high accuracy, low power consumption, stable zero point, and convenient parameter setting. Click on the Chinese display LCD to show accumulated flow, instantaneous flow, flow rate, flow percentage, etc.
