Start-up Examples
Take valid regulations and DIN ISO 748 standard as a basis
When selecting measurement places in open channels or water bodies necessarily observe
applicable regulations and the text of the DIN ISO 748 standard “Hydrometry - Measure-
ment of liquid flow in open channels using current-meters or floats” (ISO 748:2007)”.
This section explains two parameter setting examples for usual NivuFlow 650 applications step
by step.

28 Example 1: Measurement in open Channels
28.1 In General
The first measurement example is performed in an open rectangular channel.
NIVUS rod sensors are used here as transit time sensors.

More information on holders for sensor installation on vertical boundaries of water
bodies or channel walls can be obtained from your local representative or directly from
NIVUS GmbH.
In order to set measurement place parameters the basic settings below are required at
least:
• Number of paths and path arrangement
• Measured medium
• Shape and dimensions of measurement place
• Sensors used and respective positions
Observe the preparatory measures and other information for the measurement
section as provided in the “Installation Instruction Transit Time Sensors”.
