Portable measurement equipment for unattended process monitoring and verification of liquids in tanks
In nuclear fuel reprocessing the emphasis is usually placed on continuous production over long uninterrupted periods of time. The inspectorates have the task of inventory and accountancy verification which must be performed in full compliance and cooperation with the operator, in order to minimize any interruptions and downtimes, etc. To achieve the objective of minimal interference to the operator whilst maintaining the requirements and needs of the inspectorate, portable measurement units for the monitoring of the liquid contents in tanks have been developed. These units can be used for confirmation of tank calibrations and for unattended verification of volume measurement. The units are small and lightweight and can be easily and quickly installed in parallel to operators' pressure measurement equipment. The equipment uses compact digital pressure modules with RS485 data protocol communication. Dedicated software monitors and controls the equipment, from large distances if necessary, providing a user friendly set-up for the inspector's requirements, including such parameters as data acquisition, sampling rate, data storage, alarm levels and on-line visual monitoring. Protection is provided from interference and power failure. The data can be retrieved for eventual elaboration and analysis. The system has been fully tested and installed in three reprocessing installations.
