This technique significantly cuts costs for tank calibration
Mettler-Toledo
RapidCal Tank Scale Calibration (photo) replaces time-consuming and cumbersome test-weight, flowmeter or material-substitution methods. Instead, a downward force is applied with hydraulic equipment that mimics tank-scale loading during normal operation. By doing the calibration this way, piping- and understructure-influences are accounted for, and this provides higher calibration accuracy. The RapidCal reference system has an accuracy of 0.1%. Reference load cells provide traceability to applicable standards. RapidCal also avoids the tedious tank emptying and cleaning for material substitution, which in turn eliminates contamination risk and disposal costs. The effective downtime of a facility is limited to a few hours per calibration. There is no need for expensive deionized water, which has either to be disposed or stored after completion of the calibration. Hall 1, Stand 214 — Mettler-Toledo GmbH, Gießen, Germany
