The MC-LEVEL probe is a level meter with microprocessor capable of supplying an analogue signal proportional with the level of fluid in which the probe is immersed. The fact that there are no electrical parts in direct contact with the fluid mean that it can be used even in harsh or pollutant environments.
The system is split into two parts: the section with microprocessor control and level probe. The control section has a 2-figure numerical display that indicates the related level and 3 keys for programming the operating parameters.

The probe can be sized for the type of container in which the level is to be measured and may be of various shapes (circular, square, etc.) and diameters (from a few millimetres to several centimetres); it may also be made of various materials: metal (stainless steel, aluminium etc.), plastic or even glass, and this means that it can be used in many environments.
The MC-LEVEL meter has 7 outputs:
-
An analogue output 0-10V proportional with the level
-
6 on/off outputs that indicate the following conditions: full alarm and pre-alarm, empty alarm and pre-alarm, level ok and out of scale.
There is also a serial interface RS485 so that the meter can be interfaced with a PC.
The MC-LEVEL sensor has 2 operating modes:
