Inspection of flow measuring equipment for hydraulic inspection - Water and Wastewater

Planning / Conception

• Gathering of information on flow measuring equipment prior to tendering
• Visual inspection of flow measuring equipment
• Inspection concept considering local conditions
• Definition of measurement points considering accessibility and hydraulic conditions
• Planning of work to be undertaken, selection of measuring systems and securing of stationary conditions

Implementation

• Assessment of flow measurement place under operating conditions regarding hydraulic conditions and measurement range.
• Check-up of relevant dimensions.
• Inspection of transmission and recording of readings.
• Installation of comparative measurement system for flow verification.
• Comparative measurement utilising various operating conditions in order to detect the relative deviation.
• Documentation of inspection.

Data

• Verification of data and plausibility
• Evaluation of discharge hydrograph during control measuring period
• Investigation of relative and absolute deviation from verification value

Data Handover

• Report on implementation of inspection: documentation of all applicable flow measuring equipment data as well as inspection methods and inspection results.
• Result: the relative deviation from check values of verified flow areas is within the limits of permissible errors.
• Two copies of inspection certificate.
