Model PFB Annular Round Fire Pump System
The Model PFB approved Fire Pump System features a round pitot tube. It is a primary flow sensor designed to produce a differential pressure that is proportional to the flow. It is a highly reliable averaging pitot tube which generates a pressure differential between its upstream (stagnation) ports and its down stream (static) ports that is proportional to the flow rate squared. It is capable of bi-directional flow measurement.
The gage is a Direct-Readout meter with a dial featuring a 270° arc for fast and accurate reading. A precision engineered, dust-tight case ensures trouble-free operation. Preso gages are protected against overload by a unique diaphragm housing design. When the pressure difference exceeds the range, the gage will accept the accidental application of up to 60 PSIG without damage. Under normal conditions the differential pressure should not exceed the range of the gage.
