Level Detector/Transmitter System
First Claim
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.

Abstract
A level detector mounts to a tank containing a liquid. The detector transmits and receives ultrasonic pulses. The pulses are processed by a microprocessor which periodically measures the liquid level of the tank. When the liquid level reaches a pre-established level, a cell phone automatically transmits data to a remote location. A schedule for emptying the tank is generated by a server at the remote location. A service man uses the schedule to visit the tank location and empty the tank. In addition, a portable charger/calibrator is mounted to the level detector to charge the power supply of the detector and calibrate the liquid level.

14. A method for monitoring a liquid level of a tank comprising:
-
employing a level detector to automatically intermittently measure the liquid level of the tank; when the liquid level reaches a pre-established threshold, automatically transmitting data indicative of the measured liquid level to a remote location; using the transmitted data to determine a schedule when the liquid in the tank should be removed; removing liquid from the tank; charging the level detector; and calibrating the liquid level measurement of the level detector. - View Dependent Claims (15, 16, 17, 18, 19, 20)
