Unlike conventional cylindrical or 
flat types, the E2K-L is attached to 
the pipe using binding bands. 
Slip-prevention tubes are also 
included to stop the Sensor from 
moving due to vibrations.

The E2K-L is not subject to the same 
restrictions on pipe diameter as 
optical sensors. It can be used for a 
wide range of diameters, allowing 
reductions in stock requirements.
