Description
- Calibrated overall system
- Sensor is always correctly positioned due to guided sensor holder
- Exactly defined pipe cross-sectional area
- Measurement under full filling with ideal flow profile
- Proven flow velocity measurement using ultrasonic cross correlation
- Variable use in different nominal pipe diameters
- Low weight, installation in shaft by one person possible
For measurements under difficult conditions
Calibrated system with unrivalled light weight and short installation length, installation by one person possible. Highly accurate measurement under full filling.
Variable use in different nominal pipe diameters.
The measurement system ensures highly accurate determination of the flow rate even under difficult conditions, such as low discharge rates or poor hydraulic flow conditions.
- Verification of channel utilisation
- Calibration basis for hydraulic calculation models
- Determination of required renovation extents
- Determination of required reservoir volumes (retention basin)
- Introduction of a channel management system
- Localisation of extraneous water volumes
- Influent control
- Throttle discharge control
- Determination of basic data for new billing networks
