Free Shipping on Orders Over $364.13 USD

The Series EFS2 Insertion Electromagnetic Flow Sensor is designed for pipe sizes from 1 to 12" and comes in three different materials (stainless steel, brass and PVC).

There are a variety of custom fittings to choose from to ensure accurate fitting in the pipe.

The Series EFS2 is useful for any applications where moving parts would be a problem, such as dirty liquids. It can handle applications where there are rapid changes in viscosity and flow.

Other applications include small pipes and chemical metering pumps.
Features
  • Long life cycle and less frequent maintenance with no moving parts to wear or break and electrodes that discourage fouling
  • Unaffected by change in temperature, density, viscosity or concentration
  • Pulse output for use with a variety of displays and controllers for remote reading
  • Easy meter mount display and transmitter accessories for local indication and Analog 4 to 20 mA output
