A RECORDING FIELD TENSIOMETER WITH RAPID RESPONSE CHARACTERISTICS

THE ADVANTAGE OF USING A TENSIOMETER-PRESSURE TRANSDUCER SYSTEM FOR THE FIELD MEASUREMENT OF CAPILLARY PRESSURE ARE DISCUSSED. THE DESIGN OF AN ACCURATE AND RAPIDLY RESPONSIVE FIELD UNIT USING A COMMERCIAL PRESSURE TRANSDUCER IS THEN DESCRIBED AND RELEVANT DRAWINGS OF THE EQUIPMENT PRESENTED. THE PERFORMANCE OF THE EQUIPMENT, IN PARTICULAR ITS RAPID RESPONSE, IS ILLUSTRATED BY AN EXPERIMENT IN WHICH THE CAPILLARY PRESSURE CHANGES IN A SAND PROFILE ARE MEASURED DURING INTERMITTENT SURFACE INUNDATIONS OF SHORT PERIOD. THE FIELD CALIBRATION OF THE UNIT USING A COMPRESSED AIR SOURCE IS ALSO DESCRIBED. /AUTHOR/
