Flange taps and radius taps are the most commonly used. Flange taps are located 1 inch upstream and 1 inch downstream of orifice plates for pipe sizes greater than 2″, and cannot be used for pipes smaller than 1.5″ diameter, but not recommended below 2″. See more Vena-contractive taps are located 1 pipe upstream and the downstream tap is located at the point of minimum pressure to ensure a … See more Radius taps are more standardized taps that keep one radius of a pipe up to one diameter of pipe upstream, but the downstream tap is … See more Corner taps are similar to flange taps, except the pressure tap is located inside the edge of the orifice plate on either side. These are common taps in Europe on all pipe diameters and in North America on pipe sizes below 2″.
