The new Watchman Niveau cleverly employs new and unique technology developed by Sensor Systems’ to self-calibrate its universal transmitter to both the size and shape of any tank. More than just a fluid level indicator the Watchman Niveau accurately determines the volume of fluid remaining inside the tank displaying this in 1/10ths to the consumer in the indoor comfort and security of their home or office, updated every hour. In common with all other Watchman models the new Niveau boasts an operational radio-range of up to 1000 metres and has a proven battery life of up to five years.

Innovative design means that fitting the product couldn’t be simpler – all that’s required is for the product’s calibrating tube to be cut to length to match the size of the consumer’s tank and the battery connected to the tank transmitter. If the tank is cylindrical in shape in the horizontal plane, in just 25 seconds, the Watchman Niveau can be converted to "shape" the fluid level it determines so as to reflect and transmit the volume contained. The technology also allows the consumer to choose the point at which the low level warning is activated. Fitted in minutes, once calibrated, the Watchman Niveau is then set for many years of trouble-free service. If in the future a new tank is required the Niveau can be easily recalibrated to suit the new tank.
