Fire pump flow meter system is precise

Fire Pump Flow Meter Systems from Preso are used instead of the typical hose valve header and hose method, and are a simple, precise and economical method of testing fire pump performance

These Fire Pump Flow Meter Systems are used instead of the typical hose valve header and hose method, and are a simple, precise and economical method of testing fire pump performance.

Flow monitoring is easily achieved by allowing the operator to read the water flow directly in GPM or LPS.

The fire pump systems primary elements are designed to produce a differential pressure to attain accurate flow measurements.

Preso offers three types of FM approved fire pump systems available for pipe sizes 2'' to 16''.

These models include the PFA Ellipse, PFV Venturi and the PFB Annular pitot tube.

Preso fire pump systems offer low permanent pressure loss and have little to no maintenance necessary.

The PFA Ellipse model features the Preso patented Ellipse.

The elliptical shape is designed with a series of ports facing the upstream velocity pressures and flow sensing ports strategically located ahead of the trailing edge flow separation.

The Model PFV features the Preso Venturi - a successful design with over 35 years of field performance in a wide variety of applications.

It can be installed in any position with minimal straight pipe requirements.

The PFB Annular is made up of a round pitot tube.

It has an accuracy of +/-3% and is capable of bi-directional flow measurement.

Each fire pump system includes a direct-readout gauge with a dial featuring a 270deg arc for fast and accurate reading.

A dust-tight case ensures trouble-free operation.

Preso gauges are made of rugged brass construction and are protected against overload by a unique diaphragm housing design.

When the pressure difference exceeds the range, the gauge 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 gauge.
