Capacitance type level meters

GR-120 type

Non-contact, continuous level measurement of liquid in a glass tube, or test tube.

This meter allows you to measure the liquid level in glass, plastic tubes, or small container continuously, without contact.
After the device is installed, the liquid level can also be checked by examining the glass tube.

Simply install the meter on a conventional glass gauge, glass tube, or test tube from the outside. There is no need to insert a float or other element into the glass tube.

Features, keys

Thanks to high precision capacitance measurement, this meter allows the measurement of liquid levels without contact.
If you install two electrodes at two positions each other on a glass surface, the level meter will converts the liquid level capacitances between these two electrodes, to continuously measure the liquid level.
As this level meter is non-contact, you can use it to measure liquid chemicals that are incompatible with metal.
After the device is installed, the liquid level can also be checked by examining the glass tube.
If a glass gauge is already installed, the meter can output the measured results as electric signals while you check the liquid level visually.

Usages, use examples
