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. |
