Watchmans
The WatchmanSonic uses a transmitter on top of the tank and ultrasonic level measurement techniques to measure, continually, the level of oil in a tank.
This information is accessed via the receiver which is plugged into an electric wall socket within the home. When the level of oil in the tank is below 10 per cent, the fuel dispensing pump symbol appears, indicating to the householder that it is time to order more oil.
All QSS tanks supplied by Semmens Oil Supplies come complete with a watchman sonic and a shut off valve/ filter bowl.
