Over the years, GVI has made significant advancements in our flow meters, beginning with our patented venturi. All our test meters are proudly made in the USA, and we machine all venturis in-house. This allows us to maintain superior quality, achieve tighter tolerances, and have a clear advantage over cast or spun venturis. Made from domestic US steel, our venturis are free from imperfections, ensuring you receive the highest quality fire pump flow meter.

We are also proud to offer a range of advanced products, including glycerin-filled gauges and digital 4-20 mA transmitter gauges, to meet diverse customer needs. These innovative solutions provide even greater accuracy and reliability for various applications.

Our meters are consistent, identical, and accurate—every time!
