Verify Dimensions
The GF90 Insertion Models have an adjustable insertion length ferrule until it is locked into position.
Verify all dimensions before locking the fitting in place. See the appropriate figures in Appendix A.
NOTE: Two types of ferrules are available. One type of ferrule is made from Teflon. This can be
tightened and loosened repeatedly at different places on the flow element. The other type of ferrule is
made from Stainless Steel. This ferrule can only be tightened in one place on the flow element. The
Stainless Steel Ferrule makes an indentation into the flow element for a more firm fit.
The GF92 In-Line Model's flow element has a tube or pipe length and diameter that is specified at the
time of order. This dimension should be double checked with the process line.
Verify Flow Direction
Verify the flow direction and orientation of the flow element before placing it into the flow media.
The GF90’s flow element has flat areas machined on the flow element near the enclosure end of the
flow element. Etched on the flow element is a flow arrow indicating the direction of flow. See
Figure 2. Align the GF90’s flow element during installation so the flat areas are parallel to the
direction of the process media flow, and the flow arrow points in the direction of process media flow.
A flow direction arrow is etched on the in-line GF92’s tube or pipe and should be pointing in the
direction of flow. Failing to install the flow element correctly will reduce the accuracy of the flow
meter.
Verify Serial Numbers
Verify the serial number of the flow element and electronics. The instrument’s flow element has a
serial number near the flat machined area or flow arrow. The same number is on the main electronics
circuit board, and on the tag of the electronics enclosure. These numbers have to match because the
flow element and the electronics are a matched set. Failure to observe serial numbers will cause
inaccurate readings.
