Confirming the Stack Height
GREYLINE insertion flow meter stem lengths vary according to the pipe diameter and the
height of the installation hardware stack. GREYLINE records the stack height dimension
provided by the customer at the time of order entry, and the information is used to size the
stem. The dimension is shown on the laminated insertion depth gage tag attached to the
meter.
Prior to installing the meter, confirm that the stack height recorded on the tag is close to
the actual stack height. Flow meter stems are intentionally oversized to allow for
variations of at least 2” in the stack height. Contact GREYLINE prior to installation if
there is any question regarding stack height or stem length. This way GREYLINE can
offer you credit for your meter if you decide to exchange the meter for one with a
different stem length. Returns may be subject to a restocking fee.
