Series EFS2 Insertion Electromagnetic Flow Sensor
Brand: Dwyer Instruments, LLCThe 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
