3. Introduction
The instrument WMS-LTC is a device designed and assembled by PASI srl.
The WMS-LTC is a conductivity, temperature and level meter.
The instrument is equipped with a display on which the temperature and conductivity
indications are shown.
The water level will be visible on the cable marked in centimetres.
The instrument is also equipped with a sound signal and LED that indicate the water
level – placed on the panel
The system consists of:
Winch with cable of the selected length equipped with probe for measuring
conductivity, temperature and level.
Batteries included.

Panel
The panel on the instrument shows information about the instrument and its functions.
The 2 lines on the display show respectively:
Conductivity level normalized to 25°C;
Temperature.
Conductivity is displayed in:
µS/cm when, next to the reported value, only the unit of measure µS occurs;
mS/cm when, next to the reported value, only the unit of measure mS occurs.
