Fire Pump System
The Preso Fire Pump Flow Meter System is an FM-approved
simple, precise and economical method of testing fire
pump performance. The Preso system may be used instead
of the typical hose valve header and hose method.
Flow monitoring is easily achieved by allowing the
operator to read the water flow directly in GPM or
l/s. Two types of meters are available: fixed for
pipe or wall mounting; and a self-contained portable
unit which includes hoses, carrying case and bleed valves.
The single most important advantage for the system
design engineer is the choice of primary elements
offered by PRESO:
- The Preso Venturi with its well known
engineering principle, little or no maintenance and low
permanent pressure loss; with minimum requirements for
upstream (5 dia.) and downstream (2 dia.) straight pipe length.
- The Preso Annular Element (Pitot tube) - also
maintenance-free and with low permanent pressure loss,
installed economically by insertion into the pipe at
right angle to the flow. The system comes complete with weld-coupling,
packing gland and instrument valves.
