Corrosion-resistant purgemeter with a ﬂuorocarbon
resin body for measuring large ﬂow rates of liquids

P-772
Purgemeter■ OUTLINEThe P-772 is an ultra-clean purgemeter made of all fluorocarbon resin.
The same extra-clean structure as the P-771 is ensured by a ﬁtting thatcan be directly coupled with tubes. Excellent sealing is achieved by
the integral main unit/tapered tube structure and the welded valve/cap
structure. The P-772 is ideal for applications for pure water, extra-purewater, and chemical solutions with a ﬂow rate of up to 45 L/min.
