DESIGN & DEVELOPMENT OF ULTRASONIC SCOUR METER

THE REPORT SUMMARIZES THE CONSIDERATIONS INVOLVED IN THE FEASIBILITY STUDY, INCLUDED IN THE REPORT AS APPENDIX A. CONSIDERATION WAS GIVEN TO HYDRAULIC PROBLEMS SUCH AS TURBULENCE, AIR BUBBLES, SEDIMENT CONCENTRATIONS AND TEMPERATURE GRADIENTS. TRANSDUCER DIRECTIVITY PATTERNS WERE STUDIED, AND VARIOUS ELECTRONIC CIRCUITS AND MECHANICAL POSITIONING DEVICES FOR THE TRANSDUCER WERE CONSIDERED. THE REPORT DESCRIBES THE UNITS PRODUCED DURING DEVELOPMENT OF THE INSTRUMENT AND THEIR MECHANICAL PACKAGING. PLANT AND FIELD TESTS OF THE SCOUR METER ARE DESCRIBED, AND THE CAPABILITIES AND LIMITATIONS OF THE EQUIPMENT ARE DISCUSSED. A COMPLETE OPERATION AND MAINTENANCE MANUAL IS INCLUDED AS APPENDIX B. /BPR/
