The Watchman Sonic Oil Tank Alarm uses the same proven technology as the Watchman Sonic oil tank gauge to detect the level of oil in your tank. It relays this information to the receiver with an LCD display which is plugged in inside to a 3 pin domestic socket. When the level reaches 10% an audible alarm is triggered to alert you to order more oil.

If the oil level starts to drop at a rate that is unexpected, due to a leak or theft then the alarm will again trigger to alert you to this unexpected event.

Simple to install, the Watchman oil tank alarm will fit most tanks and bunded tanks up to 3m in height.

  • Simple installation, no wiring required.
  • Fits tanks up to 3m in height.
  • The user can set a low-level alarm. (on/off)
  • Alarm if the oil level drops rapidly.
  • Reads in 10% increments.
  • 200m transmission range.
  • 1 Year guarantee.
  • Suitable for steel and plastic tanks.
