Special Section: Guided wave radar for inventory tank gauging – ISA

Addressing the Workforce Demands of Modern Industry. Before proceeding with the field test, the selected vendors were asked: The International Society of Automation www. Fawaz is a certified engineering consultant SCE with 20 years of experience in instrumentation and automation.

The vendor selection was biding based, since the GWR instruments from both vendors demonstrated a superior and equal performance. The instrument principle of operation is time of flight.

Fawaz has delivered many technical apj and presentations, taught several courses, and holds three patents. Measurement technology and setup: Please send us your comments and questions about this topic to InTechmagazine isa.

The GWR cable version can be extended up to 75 meters high. Tanks with internal roofs had to be empty, cleaned, and ventilated to install the new stilling pipes. The figure 7 table highlights the data.

A small displacer weight on a measuring wire from a drum is accurately positioned and balanced in the liquid medium using a servomotor. GWR technology has many advantages, which make it an attractive option for inventory tank gauging:.


ISA has the resources and expert networks that you need — no matter what position you hold in our industries. These devices can meet the inventory and custody accuracy requirements. A nozzle was required for the multiple spot temperature transmitter. Browse the products and services designed to meet the needs of these common industry roles:. For temperature measurement and since this application is inventory, a spot temperature sensor shall be used as it is allowed by API MPMS chapter 7.

We want to hear from you! Servo gauge Figure 4.

Each RTG required excavation for running new and long cables for the signals and for the external power supply, in the large tank farm area. The journey of the Saudi Aramco tank gauging project has resulted in a simple, reliable, and highly economical system for inventory tank gauging.

The project’s final scope of work was revised as follows:. The Saudi Aramco Riyadh Refinery revised the project scope for implementing inventory tank gauging on 42 tanks, and ended up with a simple, cost-effective, and fast project implementation. The project’s final scope of work was revised as follows: Over this period, the operation team conducted frequent manual gauging three times per test to check the installed accuracy of the GWR. InTech Magazine Web Exclusive: The successful results of piloting GWR for the inventory tank gauging application revealed a new and suitable solution for Saudi Aramco’s Riyadh Refinery project.


This solution is the reference for all other solutions, and it utilizes a dip tape. The existing FF segments in the refinery tank farm have been verified and found feasible to accommodate the new GWR instruments in this project. Automation Federation completes third review and update of the original Automation Competency Model.

Over one year, the refinery operation team conducted manual dipping to check the reading accuracy of the installed GWR instruments.

Float and tape gauge This solution uses a float attached to a spring via a perforated tape. For tanks with no stilling piping e.

Deviating from these requirements can generate unpleasant challenges and errors in measurement. They can be very useful in applications like molten sulfur and asphalt. A third transmitter measures the vapor pressure at the top of the tank to increase the accuracy. It used to be the Saudi Aramco standard tank gauging solution for inventory tanks.

I would not have been able to keep going to school if I had not received it. There are two internationally recognized standards covering tank gauging in atmospheric tanks. GWR is “plug and play” and a maintenance-friendly technology. Installed GWR for piloting.
