Abstract:
1. A level detector/transmitter system comprising: a level detector comprising a housing adapted to mount to a tank for a liquid having a level, a power supply, a microprocessor, a cell phone in communication with said microprocessor and an ultrasonic transceiver adapted to transmit pulses and receive echoes of said pulses and transmit signals relating to said pulses to the microprocessor to measure the liquid level of the tank, said microprocessor regulating a time interval between successive measurements of the liquid level in the tank, and controlling the operation of the cell phone for transmitting data indicative of the liquid level in the tank when the liquid level reaches a pre-established threshold; and a portable charger/calibrator adapted to mount onto the level detector and to charge the power supply of the level detector and to calibrate the liquid level as measured by the microprocessor of the detector.
