Apollo Ultrasonic is the original ultrasonic oil tank contents gauge and comprises a tank mounted transmitter unit and a plug in receiver unit. The transmitter monitors the level of fuel inside the tank and relays this data via a secure, wireless connection to the receiver unit, which cleverly and conveniently plugs into a standard electrical socket. The receiver unit displays the level of fuel inside the tank, via an easy to read LCD display, which usefully includes a low level warning alert.
