Georg Fischer Signet offers several plastic inserts as service items for our metal installation fittings. These inserts are used for Rotor-X flow sensors and if they need to be replaced for any reason, there are a few things that you would need to know to properly replace them. To insure a proper fit, please take the following into consideration:
1
Provide two of these:
• Inside diameter, outside diameter, and
wall
thickness of pipe.
• Or you may provide the pipe size, schedule,
and type: "2 in.
schedule 80 PVC"
2
Provide height of the outlet, from outside diameter of pipe to
top of the fitting.
3
These limits are necessary to insure that the insert will fit properly and allow sufficient clearance to secure the sensor.
