Daniel Venturi Tube is a low-pressure-drop metering device identifiable by its tapered inlet, tapered outlet and straight, constricted middle section. It offers constant accuracy, low susceptibility to erosion, high-pressure recovery, and installation at any angle from horizontal to vertical.
Corrosion-resistant and virtually maintenance-free, this measurement product performs in a wide variety of applications that include air, water,vapor, steam, gas, chemical substances, sludge and slurry applications. For extremely erosive service, internal surface hardening is available.
The Classical Venturi is a head pressure device that consists of a convergent cone section, cylindrical bore, and a divergent cone section. The cylindrical bore restricts the fluid flow resulting in a pressure drop. This differential pressure relates to the flow rate by applying Bernoulli's equation. The angled inlet and outlet cones help control the pressure recovery, making Venturi the most efficient of all the differential meters available. This results in lower permanent pressure loss and greater capacity than other differential meters of the same size. Permanent pressure loss is typically 5% to 15% of the differential pressure, depending on the bore size selected.
