12/05/13 - 20130319074 - Differential pressure transmitter with redundant sensors
A system for measuring flow of process fluid through process piping, includes a flow restriction in the process piping generating a differential pressure between an upstream side of the restriction and a downstream side of the restriction. The differential pressure is related to flow of the process fluid. First and...

11/07/13 - 20130291620 - Re-calibration of instruments
A pressure differential meter (13) measures and the volume flow rate of a liquid (6) and a Coriolis meter (14) monitors the density of the liquid (6). When the density as monitored by the Coriolis meter (14) indicates that density is reaching the range limit of the pressure differential meter...

08/16/12 - 20120204620 - Determining delay times for ultrasonic flow meters
A system and method for calibrating an ultrasonic flow meter. In one embodiment, a method includes disposing a fluid circulating device within a flow meter. Fluid is circulated in the flow meter by operation of the fluid circulating device. An acoustic signal transit time within the flow meter is measured...
