METODO DE ELEVADA SENSIBILIDAD PARA MEDIR FUGAS Y-O INFIL- TRACIONES DE LIQUIDOS EN DEPOSITOS DE ALMACENAMIENTO

摘要

A method of high sensitivity for measuring leakage of liquid from a storage tank which comprises introducing a sensor into the liquid in the tank, the sensor being coupled to means for sensing displacement of mass, measuring the displacement over a known period of time and calculating the leakage rate. The sensor is designed to compensate for evaporative losses and temperature changes.
