Installation and Wiring

The linearity and accuracy of the FP-6000 Series sensor depend on predictable flow conditions in the pipe and proper location of the fitting. As with any insertion flow sensor, the pipe must be full and generally free of air pockets.

2.1 Location of Fitting

The sensor must be located in a free-flowing straight run of pipe. OMEGA recommends a minimum of 10 pipe diameters of straight pipe upstream and a minimum of 5 diameters down- stream to insure a fully developed flow profile. Any obstructions to the flow will require consider- ably longer straight runs. Figure 1 illustrates several common situations and recommended piping distances.
