Electromagnetic Flow meter does not have any moving parts, ideal for wastewater applications or any dirty liquids which is conductive or water based, or for applications where low-pressure drop and low maintenance are required. It applies to measure (is fit for the measurement of ) the volume flow of conductive medium including the acid, alkali, salt solution, slurry, pulp, paper pulp, waste water.

- Pharmaceutical

Advantages

1. It is the volume flow of liquid and solid two-phase fluid (It is used to measure the conductivity which is greater than 5μs/cm of closed pipeline that and the volume flow of fluid and solid two-phase fluid flow rate.

2. And it is not affected by the temperature of the liquid, viscosity, density, pressure, liquid-solid composition, conductivity of liquid. It has high accuracy and stable working ability.

3. It can be used to measure the fluid medium of other conductive liquid or liquid-solid two-phase flow after the calibration just ordinary water without any additional calibration.
