To protect against leakage, seal all pipe
threads with an appropriate sealing com-
pound. Make sure the sealing compound
does not intrude into the flow path.
NOTE: If connecting to new male pipe threads,
burrs and curls can adversely affect accu-
racy. Correct the problem prior to turbine
installation.
NOTE: Do not over tighten the flange bolts. This
may cause the gasket to be compressed
into the flow stream and may decrease the
accuracy of the meter.
