Water Level Controller with Motor Protector

WLC - 4

Automatic Water Level Controller switching On/Off the motor when the overhead tank is full and also protects the motor from overheating and damage. Thus, Automatic water level controller serves 24 hours water supply without letting the overhead tank to become dry.
Hardware Features
  • 16 x 2 LCD Display (backlight)
  • PCF8563 RTC with 3.3 V cmos cell
  • Buzzer for alarm.
  • 12 V / 25 Amp relay for motor upto 1hp.
  • Current transformer of 5 Amp.
  • Expansion connector for : Water level tank, Full or empty.
  • Power-on Reset.
  • 8K Bytes of In-System Self - programmable Flash.
  • 512 Bytes internal EEPROM.
  • One 16-bit Timer / Counter with Separate Prescaler.
  • External and Internal Interrupt Sources.
Software Features
  • Automatic switching on/off of motor. avoiding overflow of water.
  • Auto / Manual switch for manual operation of motor.
  • Indications for High / Normal / Low. voltage status and motor On/Off /Trip.
  • Audio alarm for dry-run.
  • Over current cut-off.
  • 4 Pre-programmed alarms for witching ON the motor at a particular time.
  • Real time clock to show current time.

Automatic Water Level Controller is ideally suited for modern homes, apartments, commercial complexes, hotels, hospitals and other places where automation is necessary for controlling the motor/pump.
