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.
