Low cost, microprocessor-based system for flow evaluation in a hydraulic model using the dilution method.
An Automatic Dye Dilution Processor (ADP) based on a microprocessor is applied to a hydraulic model to process on-line dilution curves, using saline or thermodilution methods. A low cost, F8 microcomputer with minimum parts configuration was used in an Automatic Dilution Processor (ADP) system. Software allows an operator to select methods, amount of indicator to be injected, cell calibration constant, and temperature step. Care has been taken in the curve data processing, to avoid errors when recirculation occurs. The system is used, together with an open hydraulic model, for flow measurement demonstration, and the estimation of cell calibration constant.
