Overview

The liquid electromagnetic flowmeter of Shanghai Automation Instrument Factory is a high-precision and high reliability product that has been continuously upgraded and improved. The flowmeter has reached the highest level in excitation technology, lining technology, and intelligent technology. Suitable for measuring the volumetric flow rate of conductive media such as acid, alkali, salt solutions, mud, pulp, wastewater, etc. There are no protruding parts inside the measuring tube, so there is no additional pressure loss.

Product Details

Shanghai Automation Instrument Factory Liquid Electromagnetic Flow MeterProduct Overview:

Flow meters have the characteristics of measuring accuracy that is not affected by changes in physical parameters such as medium pressure, temperature, density (including solid-liquid ratio), viscosity, etc. The instrument is sensitive, has a large measurement range, strong anti-interference ability, stable zero point, and reliable operation.
