About the Daniel Venturi Tube
With over 100 years of industry use, the venturi tube is a proven and reliable, low maintenance solution to fluid measurement applications. The rugged design has no sharp edges or angles, and the gradual sloping profile makes the device less susceptible to build-up and ideal for measuring solid-laden fluids and slurries.
One of the key features that set the Venturi tube apart from other DP primary elements is the low pressure drop across the device, which greatly reduces pumping and operating costs and is ideal for LP systems where small differentials are required. Venturi tubes are commonly used for gas, liquid and steam measurement in a variety of industrial applications including oil and gas processing, petrochemicals, power generation, water and wastewater industries and more.
