SHD Electromagnetic Flow Meter Overview

Magnetic Flow Meter Overview

Silver SHD Series Electromagnetic Flow meter is perfect to measure conductive liquid, grout and slurry.This Flow meter is accurate measuring, no pressure loss and no moving or extruding parts, wear and corrosive resistance, can be installed in any pipelines.This kind of flow instruments can be used in Chemical, Pharmacy and cosmetic fields, Municipal water supply, sewage plant, food and paper factory.

Electromagnetic Flow Meter Design

Electromagnetic Flow meters Transmit and measure the flow, volumetric flow of conductive liquid, slurry.,ect.

Electromagnetic Flow meter measuring system consists of a converter and a mag flow sensor, flow sensor is installed in the required pipeline, while converter can be installed in the field or other place (that is remote Version).If it is compact design, sensor and converter integrally constructed.
