Quotes

“Measurement is the first step that

leads to control and eventually to

improvement. If you can’t measure

something, you can’t understand it.

If you can’t understand it, you can’t

control it. If you can’t control it, you

can’t improve it.”

― H. James Harrington

Coriolis Meter Technology

International Standards

API 5.6:Liquid & AGA 11: Gas; ISO 10790

Measuring Liquid & Gas

Direct measurement of mass flow, density, temperature and viscosity (multivariable sensors).

Very high measuring accuracy (typically ±0.1%)

Not affected by flow profile.

No inlet/outlet runs necessary.

High turn down ratio.

Conclusion-1

Coriolis Meter Meets Test Criteria:

Reference meter accuracy (-0.013%).

Duty meter accuracy (+0.0202%).

Volume flow is within acceptable tolerance

(+/-0.25%):+/- 0.223% over a total batch

size (174000 gal).

Better density measurement (0.1Kg/m3).

No drift during and after operation.

No maintenance during operation.

12 Saudi Aramco: Confidential

Conclusion-2

Coriolis Meter Under Site Conditions:

No empty hose effect.

Good performance unstable pressure &

flow rate.

Handle diesel contamination.

Use of the Coriolis Meter in similar

Custody Transfer

Standardization (34-SAMSS-116/34-

SAMSS-169)

13 Saudi Aramco: Confidential

Recommendation

Assess & Remedy Diesel Contamination

Eliminate Pulsating Flow.

Evaluate Proving System:

In-situ using a Master Meter or SVP.

Periodic Laboratory re-calibration

Automated Metering System.

Install metering flow computer.

Terminal Management System (TMS).
