Survey and Evaluation of Production Meter Instrumentation and Uses. Report 1.
Abstract
The purpose of this research was to evaluate modern instrumentation being used to monitor production on hydraulic suction dredges. Instrumentation covered included flow meters, density gages and production meters. It was desired to determine their accuracy and reliability as reported by dredge operators worldwide. The survey results led to the conclusion that: (a) The number of dredges in the U.S. with instrumentation to monitor production has increased from 7 percent in 1980 to 46 percent in 1989; however, the percentage of dredges equipped with production meters is only 17 percent. (b) The magnetic flow meter is reliable and relatively maintenance free as compared to the Doppler flow meter. The nuclear density meter is accurate and reliable when installed at the proper location. (c) More than 90 percent of the dredge operators which have measuring equipment agree that the instrumentation is useful in improving production rates and evaluating total solids production. (d) Current literature on dredge production instrumentation is available on several on-line databases which are continuously updated. The Engineering database (ENGI1) of COMPENDUX PLUS in particular contains several relevant articles which are easily accessible. (e) There are several manufacturers of dredge production instrumentation worldwide, who are constantly upgrading their products. Current information on products can be obtained directly from the manufacturers listed in this report.
