What we measure
Field testing records static pressure before flow, residual pressure while flowing, pitot pressure at the outlet, outlet size, discharge coefficient, and calculated gallons per minute.
PAVEY FLOW SOLUTIONS
Get the field readings and organized documentation your project team needs. PFS coordinates hydrant access, records static, residual, and pitot pressure, calculates flowing GPM, and delivers a clear electronic report.
Field testing records static pressure before flow, residual pressure while flowing, pitot pressure at the outlet, outlet size, discharge coefficient, and calculated gallons per minute.
Hydrant flow information supports fire protection design, preconstruction planning, water supply evaluation, system checks, and coordination with the authority having jurisdiction.
Send us the project address, scope, and deadline. PFS researches the applicable city or county process, confirms any required witness, verification, permit, and fee requirements, and coordinates those steps with the water provider or local authority. We confirm any applicable fees with you as part of the agreed scope.
Once the client approves the scope and the city, county, or water provider grants any required authorization, we target testing and delivery of results within 5–8 business days. Witness availability, permits, access, and other local requirements can affect the confirmed schedule.
Your flow test report identifies the test location and setup, measured static, residual, and pitot pressures, calculated discharge, and projected available flow at 20 PSI. Hydrant photographs, mapping, and a water supply curve are included when applicable to the agreed scope. The readings and calculations are labeled so your engineer and reviewing authority can follow the result.
