Our Software Solution for your Flow Measurement: Limitless Flexibility.
BIBER
Water Resources Management
BIBER is a discharge measurement application you can use both in the field and in the office. BIBER provides all necessary functions for direct collection of discharge measurement data through a field computer and for manual collection and evaluation of the flow measurement data in the office. In the field, BIBER works with all common measuring devices. The wireless transmission of current meter impulse measurements to the field computer is an excellent example of the flexibility offered by BIBER.
The BIBER device manager facilitates clear and simple management of sensors, current meters and their calibration equations as well as counters. You can configure your current meter from a selection of propellers, current meter bodies and centre pieces. Simply enter your calibration equations and leave the continuity control to BIBER. Besides NAUTILUS (by OTT) and FLO-MATE (by Marsh McBirney) sensors, BIBER is able to configure and manage sensors from any manufacturer.
Measurement procedures and data collection
Simply define your cross section, and BIBER will provide any required amount of bank points, verticals and depth measurement. Even complex measurement cross sections can be displayed effortlessly. You can specify a main measurement procedure for the entire cross section in order to facilitate rapid data collection. BIBER also allows for changes in the set measurement procedure for selected verticals. You can select from the following procedures:
One-point measurement
Two-point measurement
Two-point Kreps measurement
Three-point measurement
Five-point measurement
Six-point measurement
Multi-point measurement
Integration measurements
BIBER can automatically record impulses if you use a DELPHIN, FLO-MATE or NAUTILUS sensor. This also applies for the combination of a current meter and an impulse converter. BIBER supports you with a variety of smart functions. The measurement wizard is easy to use and offers constructive depth suggestions during measurement. The velocity distribution is displayed on the vertical for plausibility control. Every recorded measurement can be edited.
Evaluation procedure
Three methods have prevailed for the definition of the gaugings for a velocity measurement:
Spline Interpolation according to the “Pegelvorschift” (German Manual for Water Level Gauging and Discharge Measurement, see Appendix D)
Mean section procedure (ISO748 Appendix, E)
Mid section procedure (ISO748 Appendix, E)
Discharges from the partial cross-section are displayed for all evaluation procedures, and individual verticals may be excluded from the evaluation.
BIBER offers the following graphical evaluations:
Measuring cross section with water level
Measuring cross section with river bottom
Measuring cross section with surface velocity
Measuring cross section with velocity area (fv-Line)
Measuring cross section with h3/2 line and h5/3 line
Velocity distributions of individual verticals
