Pestrikov D.V.  Pressure differential-based level measuring without impulse lines and heating

Pressure differential is a proven and reliable level metering technique; however, precise measuring of pressure differential across tall columns and vessels has always posed a challenge. Emerson Process Management offers a solution enabling process operators better tank level and pressure control and overcome the limitations of conventional measuring systems.

Keywords: level measuring, pressure differential, tall tanks, impulse lines, capillaries.

Grebenyuk E.A.  Comparative analysis of the efficiency of multi-dimensional and unbound one-dimensional control charts used for process indicator change tracking

The paper examines the design techniques of control charts intended for predicting critical time changes of lab-measured process indicators. A control chart design algorithm is offered for monitoring time changes of several product's properties with autocorrelations between consecutive observations. The algorithm is based on the filtration of observations by a specially designed filter without edge effect and on the Hotelling statistics.

Keywords: level measuring, pressure differential, tall tanks, impulse lines, capillaries.
