Remote Monitoring
The GreenAmpTM Monitoring system is designed to allow either impressed current systems or sacrificial anode systems to be monitored and logged electronically. The advantage is that it has its own power source with a life expectancy of five years.
The system can simply be attached to reference cells and calibrated for any type of reference cell system. It then will data log readings for up to five years for each cell. The data can be transmitted via GreenAmpTM Daisy Chain Data (DCD). No matter where in the world, the data can be accessed and managed by a Anode Engineering corrosion engineer.
The system operates at 12 or 24 volt DC supply and reveals to personnel at any time if any reference cell is reading high or low potentials. It can also be used to locate stray current electrolysis, wharves with Cathodic Protection or unwelcome earthing drainage.
A GreenAmpTM Daisy Chain Data (DCD) module at each test point measures the pipeline potential. It typically records every hour and transmits once a day and wirelessly communicates with other boxes along the pipeline to share this data. In an area of no mobile coverage, the information is Daisy Chained wirelessly between each module until it reaches a module with mobile coverage or network access (Bluetooth, Wi-Fi etc.) The data is then uploaded to the cloud for interpretation by Anode Engineering’s engineers or to the asset owner as required through a dedicated website/server arrangement.
This removes the need for expensive satellite connections and even minimises the requirement of mobile network connections. A GreenAmpTM DCD system reduces costs, saving countless hours of planning and driving whilst reducing the need for personnel in the field along with the associated occupational health and safety issues. Not to mention land access, weed management issues and weather delays.
The modules have been tested to Daisy Chain with a wireless range of 10 kilometres and repeater modules can help extend the range as required, with self-healing networking capabilities adding to the network reliability. The unit is housed in an IP67 rated housing and is designed with a battery life of five years in the field (depending on the reporting duty cycle). It is possible to extend the battery life with a small solar charger if required.
Data is also stored in non-volatile memory on a removable 8Gb SD card which will log over 30 years of recordings as a back-up.
The GreenAmpTM unit is capable of being configured for High-Resolution Recording and Interrupt (HRRI) at specified times to get on and off readings. Contact Anode Engineering for interrupt with relay option.
The standard unit comes as single-channel but can be extended to 4 or 8 on request.
We have also incorporated the latest communications protocols within the unit to provide an amount of “future proofing” or ability to expand its capabilities as technology evolves. The protocols include Narrow Band Internet of Things (NBiOT), Sigfox, Wi-Fi, Bluetooth and low energy Bluetooth.
