Installation
Gas
Figure 2-8 illustrates the recommended location of the flowmeter in gas applications. The
sensor should be located on the upper half of the pipe, at least 45° above the horizontal line.
For gas applications, mount the drain/vent valve downward to allow liquid to drain. In vertical
lines, the Annubar sensor can be installed in any position around the circumference of the pipe,
provided the vents are positioned properly for bleeding or venting. Vertical pipe installations
require more frequent bleeding or venting, depending on the location.
For a remote mounted transmitter, secure the transmitter above the Annubar sensor to prevent
condensible liquids from collecting in the impulse piping and the DP cell.
