Venturi Type Fire Pump Test Meter

Gerand Make Venturi Type Flow Meter UL Listed / FM

NEW VENTURI DESIGN – This is our most exciting development of 2015.  Our engineers at GVI have studied the fluid dynamics within the venturi and identified a design change that will sweep the industry.  After initial testing, the first thing we noticed is a flat coefficient which is critical for consistent accurate readings.  Our readings were so good, we are conducting 3rd party flow testing that will prove our accuracy is closer to 0.5%.  IN ADDITION: the design is so revolutionary, we applied for a design patent which was accepted by the patent office.  This makes GVI the ONLY fire pump test meter supplier with a Patented venturi.  GVI’s new Design is FM Approved.

Venturi Tube Flow Meter, also called Classical Venturi Tube,is a Classical design differential pressure flow device.  The Venturi tube is used for the measurement of gas and fluid flow,in which there is low pressure loss primary requirement.According to type of production there are:classical Venturi tubes with cast, or machined or welded confuter.

• Provides longevity, reliability and long term performance.
• Is designed in accordance to ASME and ISO standards and it offers the highest “As Built” accuracy
• Reduced pumping costs
• Provides lowest level of permanent pressure loss of any Venturi style, significantly less than orifice plates
• Durable solution for liquids, gas, steam and mixed media
• With minor modifications the SSL can be transformed into a bi-directional flow meter
• Easily installed in any position with minimal straight pipe requirements.
• Optional: RTD

Venturi’s are very useful when considering erosion and pressure recovery restraints.

Our Venturi meters can cope with a wide range of mediums:

from Gas, water, Chemical, Crude, Slurry to even high temperature Steam,

and can be used for many apllications,

such as irigation systems, metallurgy,

power stations, chemical industry,

water suply project, etc.
