ABSTRACT:
An oil-in-water monitor for monitoring the effluent of an oil-water separator. A pressure vessel coalesces oil from the effluent and gathers the oil in a collection section which is automatically emptied after an hour. If more than a predetermined amount of oil is gathered in the hour, an oil-sensing probe sends a signal to activate a warning light valve which permit pipes to return the effluent to the separator.
If the effluent becomes too turbid, a turbidity senser activates an alarm and the valves which permit pipes to return the effluent to the separator.
If the coalescer unit clogs, an indication is given by a differential pressure gauge.
It should be understood that the foregoing abstract of the disclosure is for the purpose of providing a non-legal brief statement to serve as a searching-scanning tool for scientists, engineers and researchers and is not intended to limit the scope of the invention as disclosed herein nor is it intended that it should be used in interpreting or in any way limiting the scope of fair meaning of the appended claims.
