I'm not sure where the LED is in the photo you posted. Perhaps that dark spot in the middle.
It may indicate whether there there is power applied to the unit.

Most meters are installed so that they can be easily read from a standing position - roughly 5 feet between the ground and the bottom of the meter.

Years ago people built circuits to count the pulses and log the data on a PC.
