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

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.
