<strong>2150EX</strong> Area Velocity <strong>Flow</strong> System<br />
Section 2 Preparation and Installation<br />
2.3 Site Examples Figures 2-1, 2-2, and 2-3 illustrate typical round-pipe sites. Key<br />
items are called out in the illustration and explained below.<br />
Figures 2-1 and 2-2 represent portable installations. For<br />
details about portable installations, see Section 2.4.<br />
Figure 2-3 represents a permanent installation. For details<br />
about permanent installations, see Section 2.5.<br />
The computer running <strong>Flow</strong>link (Figures 2-1 and 2-3) or the<br />
2101 Field Wizard module (Figure 2-2) should be located<br />
outside the potentially explosive atmosphere. The computer and<br />
modules communicate with the <strong>2150EX</strong> module.<br />
The <strong>2150EX</strong> area velocity flow module measures and stores<br />
the stream data. In portable installations (Figures 2-1 and 2-2),<br />
it is attached to a 2191EX or 2196EX battery module, which<br />
supplies power to the module.<br />
As described in Section 2.6.1, the EX network cable connects to<br />
the top of the <strong>2150EX</strong> stack and extends to the interface of the<br />
safe and hazardous areas.<br />
As described in Section 2.6.2, an RS232EX isolator cable connects<br />
the computer and the site. The cable supports the data<br />
transfers between the two, and is connected to an EX Network<br />
Cable connected to the top of the <strong>2150EX</strong> module.<br />
As described in Section 2.6.3, an RS485EX isolator cable connects<br />
the site with a Field Wizard or other network device. The<br />
cable supports the data transfers between the two, and is connected<br />
to an EX Network Cable, connected to the top of the<br />
<strong>2150EX</strong> module.<br />
In permanent installations (Figure 2-3), the <strong>2150EX</strong> is connected<br />
via network interface cable CA75EX-CTL (75m) or<br />
CA150EX-CTL (150m), usually through conduit, to the 2194EX<br />
network module, located in the safe area, which serves as both<br />
power supply and network or PC connection.<br />
The <strong>AV</strong><strong>2150EX</strong> sensor cable must be routed carefully without<br />
kinks, coils, or sharp bends, and secured in place without overtightening<br />
the plastic ties. Any excess cable must be kept out of<br />
the channel to prevent accumulation of debris.<br />
The Mounting Ring holds the <strong>AV</strong><strong>2150EX</strong> sensor in place.<br />
The <strong>AV</strong><strong>2150EX</strong> sensor is positioned in the flow stream to<br />
measure liquid level and velocity.<br />
