This is electromechanical technology at its maximum. Landis & Gyr 8 rate Summator in service in my house. Our house load is measured over 6 rates and the impulses are channeled via two time switches to fall on the correct tariff slots. This set up has been in service for 201,000 hours which is about 24 years. Register 8 receives an impulse every 10 minutes from a Maximum Schalter in the L&G SR 2 time switch. An opto pulse head was installed in a Modified S200.16 meter, now a S200.17 which has a constant of 250 rev / kWh, constant Kh = 4. which lines up with the gearing. The impulses go in the Maximum demand Summator first which gives me two MDI readings, and via the auxiliary output it triggers the 8 rate Summator. Many years ago Landis & Gyr (Swiss) donated me kindly 8 sets of 25/75 teeth gear wheels to get the counter constant to 0.1. 100 and 110 Volts 50 Hz Electricity
