Page 15: Crossing Paths
With shortened inflow routes we recommend the use of crossing paths Paths which are installed in one section at the same path height are automatically recognised by deltawaveVER2 as crossing paths. The measured velocities of two crossing paths are averaged. This reduces the influence of so called crossflow effects on the accuracy Crossflows can arise with shortened inflow routes, e.g. -
Page 16: Installation Of The Electronic Unit
The location should be chosen so that the evaluation unit is not more than 100m from the measuring point, as the cables are limited in length. (systec Controls should be consulted about larger distances.) The converter cables can be extended in principle. We recommend a RG58 (Triaxial) cable as an extension. -

Page 38: The Expert Menu
Further path-specific settings can be made here. Several of the parameters shown here have a large influence on system stability. All expert settings are initialised with sensible default values. We recommend changing the parameters in the expert menu only after consultation with our trained service personnel. systec Controls Mess- und Regeltechnik GmbH Rev. 1.2... - Page 39 5.4.1.1 Auto Window To receive the ultrasound signals deltawaveVER2 opens the predicted signal reception time according to an internally calculated signal run time. This depends amongst other things on the mean temperature and consistence. Since these parameters can change under certain circumstances it is possible to automatically adapt the time of reception to the mean conditions.
- Page 40 (gain) can cause noise which influences the measurement. Gain values higher than 200-220 indicates a principle problem with signal transfer (e.g. echo’s caused by gas bubbles, misalignment of transducers,etc…) and do not help to get better measurement. systec Controls Mess- und Regeltechnik GmbH Rev. 1.2...

Page 50: Damping
Technical Reference and User’s Manual deltawaveVER2 calculates the temperature of the medium from the measured sound velocity.
