- Finally done a test run with this 8 register and totalizing counter, summation meter.
These meters were used where multiple feeders in a large plant or substation are in use.
Impulse contact watthour meters provide pulses to drive these totalizing meters which could be installed in a control room.
These meters can also be used for impulses from gas or water meters.
Happy Easter !

The fact that all this can be done with modern computing wizardry is one thing, but you just can't beat the mechanical enjoyment of watching how it was done back in the day. I'm sure I was borne a decade too late 🤔
Beautiful mechanisms! Love the meter group, you have a fantastic collection!
🤔🤯
Watching that device operate is mesmerizing
0:28 pretty device too 😻
8 Siemens selenium rectifier packages, the nice little 100V 1A units. They are very nice looking, in that aluminium case, and I have seen a good number still in service despite being a half century old, and working well.
Was looking forward to this video. Very interesting with the ratio gears compared to our modern electronic metering with CTs & serial comms. Used still use hall effect sensors to digitize some of the water and gas metering theses days, yet others in factories would use modbus or a profibus serial type of comms.
I do love the clock work👍👍👍👍
Well timed! Just struggling to get pulse counting to work on my Open Energy Monitor which uses an Arduino to count pulses (and input values from 6 CTs and a VT) and a Raspberry Pi to store the values in a database. This looks much more satisfying!
It's alive!
Do you issue you kids their electricity bills monthly of quarterly?
Which one of the registers is for the portazap?
But seriously, thanks for preserving and videoing there wonderful pieces of equipment.
hey Rodalco...on the topic of Electron volts...what kind of transformer does it take to make 3.0MeV - 50mA
