Design And Construction Of A Liquid Level Alarm

ABSTRACT

The Liquid Level Alarms are designed to provide warning indication when storage (Effluent, Grey Water or Rain Water etc) tank is either empty or full. Warning indication is determined by a float switch. Warnings are; Audio (buzzer), Visual (LED Pilot Light and/or Strobe). The Buzzer can be muted via a mute button. If not muted the Audible buzzer will automatically silence after 5 minutes. If a continuously sounding audible alarm is required, this can be done by changing the Jumper position on the circuit board.

The visual alarms will continue to remain on, until the alarm condition is eradicated.  A standard feature of the Level Alarm is a ‘Voltage Free’ (5Amp rated) output for connection to auxiliary devices. Controller can be installed up to 50m from the tank being monitored. Float Switch cabling is ‘safe’, low voltage circuitry.
