The rate of this flashing is proportional to the amount of power passing through the meter and so useful information is there to be collected.
Electricity meter pulse sensor.
It allows power consumption to be monitored and an alert to be issued in the case of anomaly.
Need to good ambient light shielding around sensor.
The led pulse sensor picks up the light output pulses from a single phase or 3 phase energy meter and converts this into an electrical pulse.
The led pulse sensor is designed to work with the meter logger 100.
Emonth gas with phototransistor or reed switch.
British gas smart meters part 1.
The electric pulse can then be used in a suitable logger to monitor energy usage.
The sensor can be easily stuck on to the front surface of any utility meter with an led pulse output.
