Waste disposal monitoring system

摘要

A monitoring system (10) for a fluid waste disposal system is provided. Fluid waste is transported from a source (12) through a valve (16) to a reservoir (14) under access control provided by access switches (40). The monitoring system (10) includes density circuitry (64) for monitoring the density of fluid being deposited into the reservoir (14). Level detector circuitry (90) is provided for monitoring the level of fluid which has been deposited in the reservoir (14). The monitoring system (10) further includes a counter (56) for counting the number of times the valve (16) has been actuated. Counter delay circuitry (54) provides an output to counter (56) to positively indicate that an access switch (40) has been actuated.
