Eagle Array Pipeline Integrity FAQ

Eagle Array > Eagle Array FAQ

What are the primary Eagle Array applications?
The Eagle Array is designed to provide precise measurements of metal loss (absolute and rate of change), monitor pitting, cracks and similar flaws. The array sensors can also transmit and receive between each other in order to monitor inter-sensor flaws.

How are the ultrasound sensors calibrated?
The Eagle Array ultrasound sensors are calibrated prior to installation and re-calibrated, if necessary, remotely by software-comparison to an internally-stored reference.

Are the sensors intrinsically safe?
Initial delivery of arrays are designed for Class 1, Div 2, Group D environments. Arrays designed for Class 1, Div 1, Group A,B,C and D environments.

Does the wireless interface with a HART mesh network?
Yes. The sensor arrays can be integrated into a wide range of wired and wireless protocols.

Does it work on cellular networks?

Can the customer install the units?
The arrays are required to be fitted by a trained and certified installer but customer installation packages are available.

Can the array operate from solar power?

How long before the batteries have to be replaced?
Sensors equipped with solar arrays with battery backup are anticipated to last between 7 to 10 years.

How does the vibration sensor operate? 
The vibration sensor uses a 2-axes sensor based on iMEMs sensing technology with a built-in signal processor

Does the Eagle Array notify the customer if an unusual event or threshold is noted?
Yes, arrays are programmed to send an email to the customer if values exceed pre-set levels established by the customer.

All installations include a warranty of 12 months. Leased units have a life-time warranty and are replaced or repaired at no charge to the customer.

Ultrasound frequency?
3.5 or 5.0 MHz. Other center frequencies are available depending on customer requirements.

What size pipes can it fit on?
No size limitations, including elbows, transitions, valves and reducers.

How many sensors per array?
Standard arrays have 8 ultrasound transducers, a vibration sensor and a temperature/humidity sensor. There is no limit to the number of ultrasound transducers that can be interfaced to the arrays.

How many arrays per facility?

Can the arrays be installed underground or underwater? 

Can the arrays communicate with each other?
Yes, depending on the communication protocol selected.

Can the sensors be integrated into a plant network?
Yes, depending on the network and communication protocol.

What type of data encryption is available?
Several encryption schemes are available: WEP (Wired Equivalent Privacy), WPA (Wireless Protected Access), WPA2 (Wireless Protected Access 2), WPA Enterprise (Wireless Protected Access Enterprise)
