Target Flowmeters

The size of the probe-type target meters is unlimited, and the size of inline designs range from 12.5 mm to 0.2 m (0.5 to 8 in.). The measurement error of inline units is about 0.5% FS, and that of the probe designs, about 5% FS at a rangeability of 3 1. They can be used at temperatures up to 650°C (1,200°F) and at pressures from atmospheric to 200 bar (3,000 psig). 

In a target flowmeter, a target or impact plate is inserted into the flowing stream, and the resulting impact force is detected. The target meters are more expensive than orifices, but because they have no pressure taps to plug or freeze, they are better suited for applications where the process fluid is sticky or contains suspended solids.
