Assembly for 3" through 24" PT Meter

CAUTION!

MECHANICAL EQUIPMENT DAMAGE

See

prior to assembly.

Failure to properly clean and inspect all parts according to

may result in meter

damage and improper operation.

Procedure

1.

If rimmed rotor meter, install deflector ring by sliding it, widest edge first, into
upstream end of meter housing until contacting the step in the bore.

Note

Rimless rotor meters do not have a deflector ring.
