Watchman Sonic

Electronic Remote Oil Monitor Reading Gauge

The Watchman Sonic Oil Monitor, an electronic oil level sensor remotely monitors the level of oil in the tank. A green transmitter is fitted to the top of the oil tank and an ultra sonic level measurement is transmitted to a level sensor receiver. This information is accessed via the receiver which is plugged into an electric wall socket within the home. A Watchman Oil Monitor will continually monitor the oil level and when it is below 10 per cent, the fuel dispensing pump symbol appears on the receiver as a reminder to order more oil.
