Setup
Follow the guidelines below when setting up the 1179 flow controller.
1. Set the controller into position where it will be connected to a gas supply.
Placement of flow components in an orientation other than that in which they were
calibrated (typically horizontal) may cause a small zero shift. The zero offset can be
removed according to the instructions in
How To Zero the Flow Controller,
page 40.
2. Install the flow controller in the gas stream such that the flow will be in the direction of
the arrow on the side of the controller.
3. Allow adequate clearance for the cable connector and tubing.
Straight Shielded connectors require approximately 3” height. Right Angle connectors
require approximately 2” height.
4. Position the flow controller to provide access to the zero potentiometer.
The zero potentiometer is located on the inlet side of the flow controller body.
Refer to Figures 1, and 2, page 28, for outline dimensions, and Figure 4, page 29, for mounting
dimensions of the flow controller.
