Sentinel Location - Panametrics Sentinel User Manual

1.6.1

Sentinel Location

For both uni-directional and bi-directional flow (see Figure 5 and Figure 6 below), a minimum of five diameters of
straight pipe shall be provided by the customer on either side of the meter run, directly upstream of the flow
conditioning plate and downstream of any disturbances or pipe bends. An additional length of straight pipe will help
produce a more symmetrical flow profile, thus reducing the measurement uncertainty.
