i continue to run my old pressure river level sensor with my new ultrasound river level sensor. i found the cable from pressure sensor (at river bottom) to prioprietary transmitter (above flood level) very inconvenient, whereas ultrasound sensor/transmitter are together (above flood level), much more convenient. as i am measuring out in the open, i don’t have the echo issues described for a tank. but i will add that there are pressure sensors avail for LoRaWAN. cheers ⊣GE⊢
