A fluid monitoring apparatus has a canister into which fluid is introduced via an entry port at the top of the canister, a conventional volume measuring assembly within the canister and a flow control assembly that receives the fluid from the entry port and discharges the fluid at a controlled rate into the volume measuring assembly. The canister has a tubular body portion made of transparent plastic on which volume indicia are inscribed and is closed at its ends by a cover plate in which the entry port is formed and a floor plate in which a discharge port is formed. A pump connected to the discharge port is operable for removing fluid from the canister and is flushed with antiseptic solution via a second pump. The flow control assembly has a partition that extends across the interior of the canister and has an upwardly extending flange to form a fluid catchment and an integral funnel that discharges into the volume measuring assembly. A filter is provided across the canister or funnel. A suction port is formed in the cover plate and separated from the entry port by a partition that extends across a perforated cup that is secured to the cover plate about both ports and encircled by a tubular splash shield. Probes, including a pH probe in the cover plate, extend into the canister and an injection port is formed in lower portions of the canister.

A fluid monitoring apparatus comprising: a canister having a tubular body portion with an upper end and a lower end; a cover plate extending across the upper end of the tubular body portion of the canister, the cover plate having an entry port for introduction of liquid into the tubular body portion

A fluid monitoring apparatus comprising: a canister having a tubular body portion with an upper end and a lower end; a cover plate extending across the upper end of the tubular body portion of the canister, the cover plate having an entry port for introduction of liquid into the tubular body portion and a suction port so that air pressure within the tubular body portion can be lowered for drawing fluid into the entry port; a floor plate extending across the lower portion of the tubular body portion of the canister; volume indicator means disposed within the tubular body portion of the canister below the entry port for receiving the fluid introduced into the tubular body portion and providing an electrically sensible indication for each of a series of selected volume increments of fluid introduced into the tubular body portion of the canister; flow rate control means disposed between the entry port and the volume indicator means for limiting the flow rate of flow of fluid into the volume indicator means; and a fluid separator mounted on the cover plate so as to be disposed within the tubular body portion of the canister, the fluid separator comprising: a perforated cylindrical cup secured to the cover plate so as to extend about the entry and suction ports; and a partition plate extending diametrically across the perforated cylindrical cup between the entry port and the suction port so as to divide the perforated cylindrical cup into non-communicating entry and suction chambers.
