The insertion turbine flowmeters are used in leak detection flow applications to check the integrity of the pipelines in the petroleum pipeline industry. Typical accuracies of 1% are possible with the HP insertion and can approach I0.25% depending on the type of transmitter specified with the flowmeter. The HP insertion can be specified for use in velocities up to 50 fps (15 m/s), allowing pipeline companies to move a maximum amount of product in the shortest time possible. The insertion meter can be used in medium to large diameter pipes and can be installed and removed from an active line without interrupting service. Applications range from 4 to 72 in. (100 to 1,830 mm) pipe diameters.
