Fiberglass Reinforced Plastic Venturi's

For water and air applications in municipal plants Tech Tube recommends its all FRP construction. Only fiberglass reinforced plastic is in contact with the fluid except for the stainless steel connections in the holding flange. The FRP construction provides a durable. dimensionally stable ftow element with the highest degree of corrosion resistance for most applications. Many modified versions of the venturi. often referred to as flow tubes, have been developed in recent years. These designs sometimes provide a slightty lower permanent pressure loss, but they do so at the expense of accuracy, stability of differential pressure signal, or longer upstream piping requirements.
