Liquid measuring system and methods
First Claim
1. A method of profiling a waveform of echo signals received by a transducer in an ultrasonic fluid measuring system, said method comprising:
- measuring the amplitudes of peaks of cycles of said waveform;
calculating the absolute values of differences of said amplitudes between adjacent cycles of said waveform;
identifying the cycle of said waveform having the largest absolute value difference over an adjacent cycle; and
utilizing said identified cycle of said waveform to detect subsequent ones of said echo signals.

Abstract
Ultrasonic apparatus determines the fluid depth, volume, and temperature in a storage tank. A system description for monitoring an underground storage tank containing gasoline is described. The system determines the water'"'"'s and gasoline'"'"'s depth, volume, and temperature. The apparatus consists of a remote console, ultrasonic probe, and interconnecting cable. The remote console contains a display to report tank information and a computer to operate the probe. The probe consists of an ultrasonic transducer above the bottom of the probe facing upwards to transmit and receive ultrasonic signals, vertically spaced reflectors and a temperature sensor to measure fluid temperature.
