Keller Surface Level Sensor
Keller PR-46 X Surface Level Sensor for accurate measurement of surface water. This Swiss made sensor combines high precision and reliability. Accuracy as a result of a ceramic measuring cell for low pressure ranges and µP-electronics for level monitoring. 10 m of Kevlar Cable is supplied with every sensor. Also Keller PR-46 X sensors are compatible with Van Walt telemetry. Therefore Keller PR-46X water level sensors deliver high accuracy for surface water level monitoring. So is the preferred choice for monitoring surface water. High precision and reliability from Europe’s leading manufacturer of pressure transducers.
