L450 Level Sensor
Rev. E
Pressure Transducer for measuring water level,
Pressure sensor with analog 4-20mA output and Barometric
Pressure compensation.
Basic Handling & Operation:
Ensure that the cable is handled & stored with large loops and NOT
KINKED (which blocks the barometric pressure compensation tube).
Big Loops, No Kinks
Installation Notes:
Groundwater Installations:
• Terminate cable into a dry enclosure – to avoid moisture entering
pressure compensation tube in cable.
• Secure the Sensor Cable: Ensure that the cable is clamped securely
to topside hardware BEFORE deploying sensor down well.
DO NOT EXCEED THE MAXIMUM RATED DEPTH OF THE SENSOR
OR IRREPARABLE DAMAGE TO THE SENSOR MAY OCCUR!
It is not necessary to locate the sensor at the well's bottom – merely
below the lowest likely water level.
Avoid cable entanglements by installing sensor at least ten feet
above the well pump.
Open-Channel Installations:
Keep debris, silt or mud away from
sensor (eg: Open Channel
installations) by housing sensor in
perforated conduit or wellscreen.
• Use Long-Sweep Elbows (PVC conduit fittings) to
ease cable deployment through conduit for riverbank
monitoring of flow / level in open channels.
