Use the following steps to attach the FB104 and Pulse Interface
module to a rotary meter:
Determine which threaded hex shaft adaptor to use.
1.
The short adaptor has a 0.126–0.128 inch inner diameter at one end
and a 0.110–0.112 inch inner diameter at the other end. The short
adaptor requires a rotary meter shaft length of 0.150–0.210 inch.
The long adaptor has a 0.187–0.189 inch inner diameter. The long
adaptor requires rotary meter shaft length of 0.150–0.260 inch.
If you use the short shaft adaptor, determine which end of the
2.
adaptor fits tighter to the shaft. The end that fits tighter is the end on
which you install the set-screw.
Loosely install the 5-40 set-screw into the appropriate hole on the
3.
shaft adaptor. The kit includes two set-screws: 0.125 inch and 0.188
inch long. The 0.125 inch long set-screw is for the long shaft
adaptor. The 0.188 inch long set-screw is for the short shaft adaptor.
4. Place the adaptor with the set-screw inserted over the rotary meter
shaft, and tighten the set-screw to lock the adaptor in place.
