Measuring low water in streams accurately

To recap from a previous blog, a project looking at effects of drought conditions is monitoring the low water depths in-stream, with transducers that have a capability of reliably measuring changes of ±0.01’(feet) in low water conditions, connected via an open interface 4-20mA  to an Onset U30 cellular wireless logger. For reliability,  it was decided to use two water transducers per logger. Over ...[Read More]

We hav...[Read More]

I’ve made some changes to the board connections so that it will solder to the probe housing ...[Read More]
