Venturi tube is a device made up of an entrance cylinder connected to conical convergent cone, a cylindrical throat & a divergent section. The internal surface of the device is cylindrical & concentric with the pipe centreline. Eureka’s VEN series is suitable for measuring liquid, gases as well as steam flow. Since there is no sharp edge or protrusions in the flow section, the Venturi offers a very low pressure loss & high measurement accuracy.
