Abstract
The present invention relates to a liquid sensor for locating in a liquid. The liquid sensor includes a level sensor including one or more sensing stations located between a head and a tail of the liquid sensor. The liquid sensor is suitable for sensing the liquid level. The liquid sensor further includes a depth sensor for sensing the depth of the tail in the liquid. The liquid sensor is particularly suited to pumping station applications.
Claims19
A wastewater sensor to be located in wastewater, the wastewater sensor including:
- an elongate body defining a head and a tail;
- a level sensor including one or more sensing stations supported by the body between the head and the tail and for sensing the wastewater level, each sensing station including one or more electrodes for contacting the wastewater and through which electricity can enter or leave the wastewater;
- and
- a depth sensor fixedly supported by the body to sense the depth of the tail in the wastewater wherein the depth sensor includes a pressure sensor wherein the pressure sensor is releasably engaged within a bottom cap located at the tail, the bottom cap able to be separated from the rest of the body whilst bearing the pressure sensor.

A wastewater level monitor to be located in a wastewater well, the wastewater monitor including:
- an elongate body defining a head and a tail;
- a level sensor including one or more sensing stations supported by the body between the head and the tail and for sensing the wastewater level, each sensing station including one or more electrodes for contacting the wastewater and through which electricity can enter or leave the wastewater;
- a depth sensor fixedly supported by the body to sense the depth of the tail in the wastewater wherein the depth sensor includes a pressure sensor wherein the pressure sensor is releasably engaged within a bottom cap located at the tail, the bottom cap able to be separated from the rest of the body whilst bearing the pressure sensor;
- and
- a controller electrically coupled to both the level sensor and depth sensor so that readings of the sensors can be cross-checked for integrity.
