ABSTRACT:
A pressure-responsive instrument such as an indicator or recorder for use with a bubbler type of sensing probe for monitoring liquid depth or flow in a sewer pipe or the like. The instrument housing contains means for regulating the rate of bubble release to such probe and also contains means for diverting the bubble release temporarily to an adjacent bubble rate test location. The same housing also preferably carries a manifold for supporting bubble fluid containers and means for regulating the resulting bubble fluid pressure in the manifold, for connection to such probe.
