Product Description

The LMK307 immersible waste water level sensor has a stainless steel housing and a flush ceramic diaphragm which prevents from the build up of solids of time and makes it easy to clean.

Available in level ranges from 4 up to 250 meters of water gauge.

Product Applications

Leachate tanks above ground

Measure the level of leachate in above ground tanks on landfill sites. Leachate is the liquid that has drained from a land-fill site which consists of rainwater mixed with harmful substances from the breakdown of landfill waste. Leachate must be prevented from escaping into the surrounding groundwater and therefore it is extracted from the landfill and stored in tanks where it is eventually transported away for treatment.

Product Help

Level of emulsion with 7mm dia solid particles

Is it possible to measure the static head pressure of an emulsion containing solid particles ~7mm diameter?

If there is significant fluid movement you may need to support and protect the sensor and cable from damage. To prevent the solid particles touching the sensor diaphragm, we would suggest keeping the nose cone fitted. However, if the emulsion has a high viscosity this may lead to clogging of the nose cone. This will prevent the static head pressure being applied to the sensing diaphragm. The nose cone should be regularly inspected and cleaned when necessary to remove any sign of clogging.

Solvent paint

We want to measure the liquid contents of solvent paint in a 4 metre high cone bottom round tank.  There is a hole in the top of the tank for lowering the sensor inside.

We would suggest a LMK 307 with FKM seals and FEP cable.
