This is a Sangamo S309.2 on my service, the dual-tariff version of the Sangamo pictured above. This one doesn't have the remote reading facility.

Thanks Pauluk for the quick posting of the kWh meter photo's.
This way we can make up a very interesting data base on ECN for all different topics in our trades.
A photo says sometimes more than a 1000 words.
Cheers Ray

I had to take a photo while visiting my parents in law over Easter where I noticed the new replacement meter fitted about 3 months ago by the POCO.

Our Poco in Brisbane have been using them. I was talking to one of their guys the other day and he recently discovered all the Iskra meters in 3 buildings of a large unit complex had stopped working. It seems they don't handle surges very well.

That's not good.

The biggest problem with electronic meters is that a surge will hit the meter first before doing damage downstream of the meter,
regardless of the internal meter surge arrestor which I have seen blown off the circuitboard in Enermet and Landis & Gyr meters.
No doubt we will have some problems with these Iskra meters too.

I reckon The Australian Email M1, M2 and M3 and SDM polyphase version meters are the best in handling power surges.

Joure, Friesland, The Netherla...
Our PoCo (Nuon) over here in the Netherlands
only installs those ISKRA meters from now on.

Also for replacement of the old mechanical meters and for service upgrades.

I'd really love to get an old Reimer&Seidl meter once... mostly because the company used to be located in a small basement shop 5 blocks from where I live...

This is a Russian kWh meter which I spotted on Ebay a while ago.

This one has a 5 dial register. Sometimes you see them with a 3 or 4 dial register.
