IMPORTANT
• In vertical mounting, ALWAYS make sure ULTRA YEWFLO is mounted with the
wiring port facing downward, as shown in Figure 4.2-3, to prevent against the ingress
of rainwater, etc.
4.2.2 Installing a Flange Type of ULTRA YEWFLO
• Using stud bolts, nuts and gaskets, install ULTRA YEWFLO as shown in Figures 4.2-
5 and 4.2-6.
• It is always the user’s responsibility to procure gaskets for flowmeter mounting (see
Figure 4.2-1). (In order to prevent gaskets from protruding into the flow path, use
gaskets with pre-cut bolt holes whenever possible.)
IMPORTANT
• Use gaskets whose inner diameter is greater than those of ULTRA YEWFLO and the
joint pipe. Exercise extreme care to prevent the gaskets from protruding into the flow
path.
