<strong>2150EX</strong> Area Velocity <strong>Flow</strong> System<br />
Section 2 Preparation and Installation<br />
Note<br />
The <strong>2150EX</strong> requires <strong>Flow</strong>link 4.1 or later. If you require two<br />
minute data storage intervals, you will need version 4.16 or<br />
later.<br />
Refer to Section 3 and define the following properties:<br />
• Level - Enter a liquid level measurement to adjust the<br />
level readings from the <strong>AV</strong> Sensor.<br />
• Zero Level Offset – If the <strong>AV</strong> Sensor is not installed in<br />
the bottom-center of the channel, an offset distance<br />
must be entered.<br />
• Set <strong>Flow</strong> Rate to zero if no velocity data checkbox<br />
- Determines how the <strong>2150EX</strong> reports flow rates if<br />
stream velocity data is not available.<br />
• <strong>Flow</strong> Conversion – The <strong>2150EX</strong> can store flow rate<br />
readings. To correctly convert the measured level and<br />
velocity readings to a flow rate, the flow conversion<br />
method and channel properties should be defined.<br />
• Silt Level – (Area Velocity <strong>Flow</strong> Conversion Only) The<br />
<strong>2150EX</strong> can compensate for a build up of silt around the<br />
<strong>AV</strong> Sensor.<br />
These five settings should be considered a minimum<br />
requirement. Other settings, such as Data Storage Rates, Site<br />
Name, and <strong>Module</strong> Names, also may be set using <strong>Flow</strong>link.<br />
