Thanks. Temperature coefficients, compensations – that’s interesting. I have the sensor sitting in a bucket of stream water right now – should see more rapid changes in temperature. I’ve a note into the METER Co.

Sure. https://monitormywatershed.org/sites/VCRP1/

Best way to view it is with time series visualization. Exclude interruption of pattern by a rain event and having the sensor out recently over a recorded reading.

No luck. I disconnected the solar panel, but am still seeing artifactual troughs. It’s reminiscent of the much more extreme variations in reported stream depth for the Pine Creek station, which calmed with a new sensor. The latter might have been related to a frayed wire from the sensor, I’m not sure.

Yeah – the sensor was cleaned recently. I had also switched the logger on and off. I’ve now replaced the battery. No luck – the trough and flickers, though slightly modified, still occur. I’ll try to substitute in another sensor, possibly another logger, in order to isolate the problem.

Thanks, Brian. What I’m really looking for is the Mayfly sketch, one specifically for an SDI 12 interface.
