Protections

The installation of SOFREL protections is strongly recommended. They conform to current standard and have been specifically designed to efficiently protect telemetry and SCADA hardware.

CNPR / CNPI / CNPA sensors

Particularly robust and accurate, SOFREL sensors are designed to meet the most demanding level and pressure measurement requirements for both water and waste water disposal:

- CNPI: submerged sensor for drinking water level measurement, etc.
- CNPR: connectable sensor for pipe pressure measurements
- CNPA: submerged sensor for measuring raw sewage levels in lift stations or catchment basins.
