1. Apparatus for remotely receiving sensor data from a liquid quantity sensor associated with a liquid container, comprising:
- sensor control means coupled to the sensor for producing a first electromagnetic signal based on the sensor data, and a mobile remote control means for receiving said first electromagnetic signal and producing an output based on the sensor data;
said sensor and sensor control means being selectively powered in response to a signal from said remote control means to produce said first electromagnetic signal and being substantially deenergized other than to produce said first electromagnetic signal.
