Levels & pressure sensors

Levels & pressure sensors

SOFREL CNPI and CNPR sensors have been specially designed to measure water level in tanks, vessels, wells, etc.
These piezoelectric sensors determine the water depth by measuring the differential pressure between the liquid surface and the tank bottom.
They incorporate fully isolated electronic components and offer excellent robustness in the most severe operating conditions (shocks, humidity, overvoltage).
Totally compatible with SOFREL RTUs and TELBOX, they provide reliable and accurate remote monitoring of drinking or cloudy water level measurements. They can be immersed (CNPI) or externally connected (CNPR).

CNPI

Used to measure water levels in tanks, vessels, wells, etc. It determines the height of water by measuring the differential pressure between the surface of the liquid and the bottom of the tank in which it is immersed.

CNPR

Used to measure pressure in hydraulic or pneumatic ducts. It connects to a standard thread and delivers a signal proportional to the pressure in the duct.

CNPA

Specifically designed for waste water disposal, raw sewage or rainwater, it is fitted with a high-resistance ceramic cell enabling it to maintain maximum accuracy despite the occasionally chemically highly aggressive effluents encountered in waste water.

Perfectly optimized for SOFREL Remote Terminal Units, the CNPI, CNPR and CNPA sensors offer a reliable and economical solution for the remote monitoring of level and pressure measurements.
