Capacitance type level meters

MHL-R1 type

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

This meter allows you to measure the liquid level in gauge tubes (glass, plastic tubes), or small container continuously, without contact. Can be easily to desorption (installation and removal) of the sensor unit in the narrow mount site.
After the device is installed, the liquid level can also be checked by examining the glass tube.

By a mechanism was devised, can be simple desorption of the sensor unit, and stable measurement. Also, no-need to install the float in the glass tube. (Patented)

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.
Can be install and remove easily gauge tube etc..
If a glass gauge is already installed,the sensor can easy install or remove to a glass gauge, it is exchangeable in the narrow site.
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

Non-contact level measurement of liquid in a glass tube, small vessel.
Non-contact liquid level measurement in a Teflon and plastic tube.
