Hello All
I had a conversation with River trac yesterday and there is some really opportunities here. They are using an Ultrasonic gauge that works up to 4.8m Its runs on AA batteries and last about a year before replacement. It use the LoRaWAN . It brings back the data every 15mins. You can get the api.
The cost hasn’t been agreed but from our off the record conversation is going to be a very very cost effective compared to the current market and in the areas of disposable cost.
