Sensing transmitter devices protected from liquid ingress when completely immersed in a leachate for measuring leachate level and converting it to a 4-20mA current output signal to send to other instrumentation.
Products
- LMK307 Submersible Waste Water Level Sensor - Submersible waste water level sensor with optional intrinsic safety certification for monitoring the level of sewage and effluent in water treatment plants.
Applications
- Contaminated groundwater submersible plastic body 5 psi pressure transducer & display - This submersible pressure transducer and display can be used by landfill site pump techs to read leachate water level above the transducer at the well head.
- 1 barg IS certified 4-20mA submersible leachate pressure sensor for tank level gauging use - An intrinsically safe submersible wastewater gauge pressure sensor for tank level gauging use to measure pressure of leachate over a range of 0 to 1 bar g from the G1/2 male process connection, and sending the corresponding 4-20mA signal through the submersible cable electrical connection.
Product Types
- Landfill Site Submersible Leachate Level Transmitters - Sensing transmitter devices protected from liquid ingress when completely immersed in a leachate for measuring leachate level and converting it to a 4-20mA current output signal to send to other instrumentation on a landfill site used to bury waste material.

A submersible device can be installed in leachate without causing any damage as long as the installation instructions are adhered to, and the specified depth and time duration limits for submersion are not exceeded.
Assembled devices are vulnerable to leachate ingress, which can enter the device through seals and joints or permeate through components that incorporate thin membranes or porous materials.
To achieve a long lasting submersible construction, the device is constructed from materials which will not easily corrode when exposed to leachate. Corrosion may cause the material to fail and allow leachate to enter the device, or interfere with the seal joining the corroded material to another component.
The seals used to join device components together are pressure leak tight, resilient to the expected temperature variations and resist corrosion from the surrounding leachate.
All components and seals are designed to withstand the pressure expected at the maximum required leachate depth, and this may involve a series of seals and backfilling with a potting compound or other fill material to improve longevity and reliability at greater depths.
A leachate level transmitter is an instrument for measuring the height of leachate in a landfill site and converting it to a 4 to 20 milliamp current loop output, which is sent to other instrumentation to display, monitor, log or control the leachate level.
The level transmitter is lowered into a tank, borehole or collection pit and immersed in the leachate. Typically a pressure transmitter is used which will measure the pressure generated by gravity acting on the surrounding leachate.
