Which DC meters are suitable for which Current Transformer Rings?
CE Transducer NDC (6 Channel) DC meter works best with the DC Current Ring rings.
ACREL AMC16 DETT DC meter works best with the ACREL Hall Sensor rings.
CE Transducer CE11 DC meter, meter can be used as a DC meter independently
and a current ring all together
How to choose the accurate DC Meter and Current Transformer Ring for my site?
There are a couple of questions you should answer to choose the most suitable DC Meter and Current Transformer Ring:
What is the current that needs to be measured?
What is the voltage?
What is the conversion ratio?
What is the diameter of a cable that needs to be measured?
The following table allows you to easily choose the required products.
Catalog numbers are internal to Galooli.
Ring Diameter/Current/Voltage | 100A/60V | 100A/1000V | 200 - 1000A |
31mm | CE Transducer CE11 (High) |

How accurate are the DC Meter and the DC ring?
Item Codes/Data | Meter | Ring | Accuracy | |||
|---|---|---|---|---|---|---|
Galooli Item Code | Voltage reading | Current reading | CT | Overall voltage | *Overall current | *Overall kwh |
CE Transducer NDC (6 Channel) (Meter) | 0.50% | 2.00% | 2.00% | 0.50% | 2.00% | 2.50% |
DC Current Ring (Ring) | 0.50% | 2.00% | 2.00% | 0.50% | 2.00% | 2.50% |
CE Transducer CE11 (Ring) | 0.20% | 1.00% |
| 1.20% | ||
CE Transducer CE11 High (Ring) | 0.20% | 1.00% | 1.20% | |||
*Overall current accuracy = Meter current reading accuracy + CT Accuracy
*Overall kwh accuracy = Overall voltage accuracy + Overall current accuracy
