Capacitance level sensors operate in the way that process fluids have dielectric constants significantly different to air.
Water level measuring devices.
They generally fall in two 2 major groups.
This happened with mine.
Point level measurement devices.
However with a little experimentation you can set the minimum depth levels to ignore reflections from non water level objects above the water column.
Other reviews have noted that the device can pick up erroneous signals from case joints and pipe fittings.
There are various types of level measurements tools.
The measurement system converts the potentiometer output to digital form and converts the results to the appropriate units of water level i e feet change.
They measure the change in capacitance between two plates produced by changes in level.
A 10 foot change in water level can be measured.
High quality workmanship means devices are built to last.
They monitor material level at a preset point which could be either a low level in order for example to avoid the danger of a pump running dry or a high level in order to avoid a spillage or leakage.
Applications tank level monitoring in chemical food water treatment power and brewery industries.
