Gerand Engineering

Gerand Buttweld Venturis are used to measure flow within the pipeline while having no pressure drop through the valve utilizing the Venturi effect. These Venturis have an accuracy rating of +/-1%

Gerand Flanged Venturis are used to measure flow within the pipeline while having no pressure drop through the valve utilizing the Venturi effect. These Venturis have an accuracy rating of +/-1%

Gerand Grooved Venturis are used to measure flow within the pipeline while having no pressure drop through the valve utilizing the Venturi effect. These Venturis have an accuracy rating of +/-1%

Gerand NPT Screwed Venturis are used to measure flow within the pipeline while having no pressure drop through the valve utilizing the Venturi effect. These Venturis have an accuracy rating of +/-1%

The Gerand Balvalve Venturis are used to measure flow within the pipeline while also manually balancing the flow utilizing our blowout proof stem with memory locking device. Available in Sweat or Threaded These Venturis have an accuracy rating of +/-1%

• 0-400 Pressure Range
• USE & OPERATION
  • Testing from floor to floor is made easy with this lightweight, accurate device.
  • Onsite valve performance or malfunction is immediately apparent.
  • Field adjustable valves can be correctly set "IN PLACE" to meet system demands.
  • Testing by dispersing the water flow down a drain riser or through fire hoses are options afforded with the NOMAD®.
  • Testing the valves will also indicate the adequacy of the water supply, including the fire pump.
