Product Introduction: Electromagnetic flowmeter is composed of sensor and converter two parts, based on Faraday electromagnetic induction rate work, used to measure the electrical conductivity of liquid or two-phase medium, the requirements of its conductivity should be greater than 5US/cm (tap water original conductivity of about 100-500US/cm), can be used to measure a variety of acid, alkali, salt solution, pulp, pulp and other media, But the medium can not contain more ferromagnetic material and a lot of bubbles.

Electromagnetic flowmeter is a kind of main flow meter, widely used in petroleum, chemical, metallurgy, textile, paper, environmental protection, food and other industrial departments and municipal management, water conservancy construction and other fields of flow measurement.

Product features: The measurement tube open flow and moving parts, so it will not cause additional energy loss, also will not cause blockage, so the energy saving effect is significant, especially suitable for liquid-solid two-phase flow such as sewage, mud, pulp, coal water slurry, pulp and other measurements.

Contact with the measured medium only lining and electrode, as long as the reasonable selection of lining and electrode materials, can achieve good corrosion resistance and wear resistance, therefore, can measure a variety of strong acid, strong alkali and other chemical solutions.

Installation requirements are low. The front straight tube section is only 5D and the back straight tube section is 2D (D is the internal diameter of the selected instrument).

Measurement accuracy is not affected by fluid density, viscosity, temperature, pressure and conductivity changes, and can be measured in both positive and negative directions, which provides a good means for accurate flow measurement.

The meter has low power consumption. It's less than 5VA.

The converter has good interchangeability and the accuracy can be achieved without re-calibrating the real flow. Because the electromagnetic flowmeter has a series of advantages, it is more and more widely used in various industries, becoming the ****** instrument for liquid flow measurement.
