Watchman Alarm Description



Watchman Alarm

PROTECT YOUR OIL! With the Watchman Alarm, you can monitor your oil tank contents 'at a glance' from your home, no need to walk outside to the tank. In the event of the oil level in the tank dropping at an unusual rate, the receiver will emit an audible alarm.

How it works
The Watchman Alarm Oil Tank Contents Gauge and Alarm consists of a battery operated ultrasonic transmitter installed on your oil tank, which wirelessly transmits a signal for up to 200 metres to the receiver plugged in to a standard 230 volt electrical socket in your home or office, so you never run out of oil again!

Product Features:

  • Alarm feature (if the oil drops more than 1.5cm a minute, an audible alarm will sound)
  • Quick and easy to install
  • Suitable for all types of tank, steel or plastic
  • Can transmit up to 200 metres
  • Can measure the tank contents on tanks up to 3 metres inside height
  • Optional audible setting, with a buzzing tone, when tank contents run low.
  • Compatible with most fuels including home heating oil (kerosene), diesel and red diesel.
  • Can be fitted to steel tanks if 32mm holes are drilled (please check your tank first)
  • Comes with complete installation & set up instructions
  • 12 Months replacement guarantee
  • See "Video" tab below for installation instructions

Watchman Alarm Delivery Information


The delivery of a tank can be confusing as each manufacturer offers a slightly different service and lead time. Please refer to our Delivery Information page.  Standard tank deliveries are "kerbside" which means the tank will be delivered to the kerb only and not positioned further. Should you have specific delivery requirements or restrictions, please contact us to discuss.


Tanks Over 2500L – Articulated Lorry – Customer Offload:

These tanks will be delivered on an articulated vehicle (approximately 16.5m long x 2.6m wide x 3m high) which has no offloading on board, it is the customer's responsibility to offload the tank, which may require a telehandler / forklift.  Curtain sided vehicles are also used, so please note that if there are obstacles or hanging branches on the road to the delivery site etc, the driver may refuse to drive the vehicle to the customer's location due to the possibility of damaging the vehicle. Please let us know if there are any obstructions before delivery, so we can arrange alternative transport.


18 Tonne Tail Lift HGV

This vehicle is the size of the largest bin lorries (for comparison) and is approximately 8.2m long x 2.6m wide x 4m high, often curtain sided so please note that if there are hanging branches etc, these vehicles will not attempt to drive down due to the possibility of damaging the vehicle and so it is recommended that a smaller vehicle is requested. Tanks will be lowered to the ground but not positioned as this is a kerbside delivery.  If a smaller vehicle is required, please email us at quoting your order number and name.


HIAB Delivery

HIAB delivery is available but must be requested and there will be an additional cost for this service. If a HIAB delivery is required, please email us at quoting your order number and name, and we will come back to you with a price for this service.



Most accessories will be delivered within 1-3 working days (certain products and postcodes may take longer, please check the product page for update to date information). If you require them quicker, we can on occasions offer a next day service (please contact us to discuss). If the item(s) are out of stock, we will advise you of the expected lead time, and you will of course have the opportunity to cancel with a full refund.
