3.17 Carrier/Calibration Bottle Rack Installation on Meter Run
The carrier/calibration gas bottle rack is used to hold the carrier and calibration
gas bottles on installations not using an environmental enclosure. A gas regulator
should be installed on each gas bottle (see Figure 3-35
). This bottle rack is not
available through Totalflow; therefore, the instructions are generalized.
