So my utility company installed a Sensus iPerl water meter. I do not think it has a transmitter attached to it. Though it does have a three wire cable coming out of it attached to nothing. Round plug on the end. I have attached an image that looks like it.
Been trying to get info about the meter but only seem to find marketing material.
Thanks
I would love to know as well. I have the same meter with a sensus flexnet (model: 501m) box transmitter/receiver attached to the iPearl meter. I haven’t been able to find any specs on how the data is transmitted from the meter to the transmitter. It would be great if it was rs-485 to be able to tap into. I’m just afraid tinkering with it may trigger a tamper alarm.
Found some data on on these documents
I am looking into using a ESP32 with a hall effect pulse sensor input. Thinking the plug might me a pulse output. Looks like it uses the Nicor plug.
Subscribing! I Just had one of these installed at my house as well. Very curious to see if we can read live data from it with an esp32
Subscribing as well. I’ve been wrestling with AI-on-the-edge and my Sensus iPerl and would love to have a simpler, reliable solution.
Still working, slowly, on this. Thought I found some plug and play, thought turned out bot be more proprietary. Actually had a conversation with one of the company, but once they found out it was for a single home and not a complex, it was like SEE YA.
So it seems that Sensus is also the actual protocol and not just a company. So looking more into that and libraries… 
Working off the concept of AI-on-the-edge, I used an ESP32 Cam module to do OCR on a cropped image of the digits. Uploaded my ESPHome config, automations, and scripts here:
