A Venturi tube is a highly accurate differential pressure flow meter used for measuring the flow rate of fluids. It calculates flow by determining the pressure difference between two points along a pipe. Constricting the pipe’s diameter increases flow velocity and decreases pressure, creating this pressure difference. The flow rate can be determined by observing these variations in fluid flow. According to the Bernoulli equation, pressure loss increases with flow rate, applicable to all pressure flow meters, including the Venturi tube. Suitable for measuring liquid or gas flow, the Venturi meter supports pressure ratings of 150, 300, 400, 600, 900, 1500, and 2500 ANSI B16.5 Class. Constructed from materials like Carbon Steel, Stainless Steel, Duplex Stainless Steel, Inconel, Hastelloy, and Titanium, the Venturi flow meter operates within a temperature range of 30°C to 400°C. Reliable venturi tube suppliers ensure quality and durability for various industrial applications. Whether you need a venturi meter and orifice meter, these devices provide precise flow measurement for a range of uses.
