Am looking for a quick and cheap solution to a requirement to provide metering for a single appliance, in this case a dairy fridge/chiller for a farmer.
The refrigeration unit is on a 13A plug and socket. and I thing the max draw when the compressor kicks in is only around 1.5A.
The guy wishes to 'rent out' the unit for a third party to use and he needs to know how much to charge for it's electricity consumption.
What would be the easiest solution to this? Leave the existing socket outlet alone and just insert some kind of meter in line with the appliance flex? (If such an item exists)
Or just insert a meter between the supply and the socket outlet concerned. Note: metering is not possible from the consumer unit end.
A 100A meter seems like overkill for what is actually needed.
Comments welcome.
