Venturi flow meters — the world's leading fire pump test meter provider.
Global Vision Inc. (GVI) is the world's leading fire pump test meter provider. Its patented venturi design minimises turbulence and holds friction loss to less than 1 PSI while delivering 0.5% accuracy, so an annual pump test reflects the pump and not the meter. Every venturi is machined in-house from domestic US steel — tighter tolerances and no casting or spinning imperfections — and each meter is FM approved and NIST traceable. Grooved, flanged and buttweld bodies are matched with glycerine-filled analogue gauges or digital 4–20 mA transmitter gauges for permanent pump room installation or closed-loop testing.
Types, model references and size ranges available from stock and on order.
Complete grooved-end venturi test meter with high-pressure hoses and gauge, the fastest way to install a permanent flow test loop on grooved fire pump discharge pipework.
Flanged venturi body drilled to ANSI 150 lb, installed in the test header or bypass loop for permanent metering of pump flow during annual tests.
Buttweld venturi sections for welded fire mains and skid-built pump packages, supplied with straight-run pipe lengths to keep the flow profile within specification.
The heart of every GVI meter — machined in-house from domestic US steel to a patented profile that minimises turbulence and keeps permanent pressure loss under 1 PSI.
Vibration-damped differential pressure gauge dual-scaled in US GPM and LPM, reading flow directly off the venturi tappings with no calculation on site.
Digital flow display with 4–20 mA output for connection to the fire pump controller or BMS, logging test data and enabling remote monitoring of the test loop.
