Real Time Validation and Monitoring that Provide Differential Pressure Meters

DP meters have been around for more than 100 years and until now, they need to be inspected at frequent intervals for any change in geometry. The TekValsys DPrometer validation system is the better way to verify.

Because Inaccurate measurement leads to:
Inefficiencies | Financial penalties​ | Legal arguments ​

- By utilizing a third taping downstream of a meter body, it is possible to read three differential pressure measurements. These three DP measurements are the core of the Prognosis system, unlocking the full self-diagnostic capabilities of the meter.

- Using the three DPreadings, the pressure field through the meter is monitored and the three DPsare compared in multiple ways using other process conditions and metergeometry, providing powerful information on the meter’s performance using purely information which is already an integral part of Why do we need to measure Accurately​? the meter without the need for any inspection.

– The diagnostic calculations are derived from well understood physical principles and industry standard calculations for DP meter flow rate. Seven diagnostic results are calculated and monitored in real time for each meter.

– The results are displayed as 4 points plotted on an 1×1 unitless box. Due to normalization (each comparison result is divided by its comparable uncertainty), if the meter is operating correctly to within its allowable uncertainties, each of the 4 points will be inside the box.
