Sensor

It is a magnetic float operated level sensor with ten set point with each point equal
to 10% of the tank depth. It gives the variable output from 0 U to 2.5k U. for each set point the output resistance will be increase by 250 U.

Indicator

Digital level indicator is a microcontroller bases electronic unit for display of
level in percentage. The level is displayed as 0%, 10%,20%.......90%,100%. The
display is through seven segment bright LED display. The unit is connected to
percentage level indicator supplied by us. The unit can be used to either switch ON or OFF the pump or providing high- or low-level alarm by selecting suitable DIP switch

Pump ON & OFF is provided in two modes

  • Pump UP Mode: to fill the tank. Here the pump is on at low level and OFF at high level. The high and low levels are field selectable between ten
    steps.
