Flowtube Site Selection
Site planning reduces process down-time, prevents connection
problems, and simplifies maintenance. The allowable distance
between flowtube and transmitter is the length of the cable run, not
the distance between their physical locations.
Requirements for a satisfactory flowtube site depend on the exact
installation configuration. Consider the following when planning a site.
Line Power Access A Model 8732C Integral Mount Magnetic Flowmeter System requires
a supply of ac power only at the transmitter, and not at the flowtube.
Check the power service requirements on the transmitter
identification tag.
Bypass Piping Bypass piping may be desirable to allow isolating the flowtube for
servicing, cleaning, and replacement. Two configurations are
shown in Figures B-1 and B-2.
Figure B-2 illustrates a conventional bypass useful for
flowtube isolation.
Figure B-1 illustrates bypass piping with a cleanout tee. A cleanout
tee is recommended when measuring greasy or insulating process fluids
that may coat the flowtube wall.
