摘要

A menu driven automatic tank calibration program was established at one of the new facilities at the Savannah River Site (SRS). Approximately 100 tanks ranging in size from 10 to 21,000 liters were calibrated. Tank level instrumentation included a precision level system using Ruska instruments multiplexed to several tanks via a Scanivalve system, standard process level differential pressure transmitters, capacitance probes, and temperature devices. Most of the tank instruments were connected to data collection computers. Scales were temporarily connected to the data collection computers to input solution weights and to record the scale calibration data. Flat panel displays were used for information feedback to operators including when to transmit weighs, data transmitted, tank instrument readings, and other procedural steps. The automated data collection permitted signal averaging and consistency checks to improve the quality of the data and minimize repeat calibrations. This paper will provide a description of the calibration system, equipment used, unique features of the system, and an assessment of the quality of the data collected.
