        I have a use case where I need to monitor water depth and discharge in an earthen irrigation ditch, and plan to use a Mayfly and MMW to collect and report the data in real-time. I estimate the ditch i

          I don’t remember exactly which models we’ve tested or which seems to be the best; maybe Shannon can pipe in.

          No matter which you’re using, definitely do get the MaxTemp.

            We usually use the MB7389 because it has the proper filtering for looking at a single target such as water, and has TTL output, so it’s easy to read with the Mayfly. They make lots of other ver

                If you all have found that a submersible pressure transducer is a more reliable way to measure depth, we may consider that. Do you have a model that you would recommend?

                Thanks,
                Matt

                  I look at the measurement accuracy, and vented depth sensors. Especially at lower water levels vented depth sensors are I believe the most accurate.
                  Good measurement accuracy starts at about 0.25% of

                    Hi Neil, thanks so much – the detail is appreciated! I need to check with our hydrology staff to learn their accuracy requirements. To date, our Mayfly deployments have used the CTD-10 from Mete

                      Hi guys,

                      I am looking for low-cost methods to measure stage in rivers and streams, and was wondering if anyone has had any success?  Neil’s transducers look great, but are too expensive for ou

                        Hi James, thanks for the agupubs reference – very nice to see the LiDar work.
                        I had talked to a LiDar guy some years ago and they had said they didn’t think it would work for streams, but
