2150EX Area Velocity Flow Module
Section 2 Preparation and Installation
2-34
Note
The 2150EX requires Flowlink 4.1 or later. If you require two
minute data storage intervals, you will need version 4.16 or
later.
Refer to Section 3 and define the following properties:
• Level - Enter a liquid level measurement to adjust the
level readings from the AV Sensor.
• Zero Level Offset – If the AV Sensor is not installed in
the bottom-center of the channel, an offset distance
must be entered.
• Set Flow Rate to zero if no velocity data checkbox
- Determines how the 2150EX reports flow rates if
stream velocity data is not available.
• Flow Conversion – The 2150EX can store flow rate
readings. To correctly convert the measured level and
velocity readings to a flow rate, the flow conversion
method and channel properties should be defined.
• Silt Level – (Area Velocity Flow Conversion Only) The
2150EX can compensate for a build up of silt around the
AV Sensor.
These five settings should be considered a minimum
requirement. Other settings, such as Data Storage Rates, Site
Name, and Module Names, also may be set using Flowlink.
