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.

Beginning two weeks ago (September 2) my EnviroDIY station (VCRP1) equipped with a METER CTD sensor began displaying troughs and flickers in recorded stream depth that don’t correspond to true changes in depth as actually measured. Weirdly, the troughs and flickers occur at precisely the same times in almost precisely the same patterns on a…[Read more]

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

Would anyone have a Mayfly sketch for rain gauges such as METER’s ECRN-50 or -100 or Campbell’s Rainvue 10 (i.e., SDI 12 interface)? If it incorporates an Adafruit Trinket, all the better, but if it doesn’t, no problem.

D_Manning started the topic Registration using a second organization in the forum Monitor My Watershed 1 years, 5 months ago
I have a stream monitor that’s supported by one organization, so when I registered the monitor on MonitorMyWatershed I used that organization’s name under ‘Organization’. That was a year ago. I am now registering a second monitor, for a different organization. I would like that (second) organization be identified with the second monitor, but I…[Read more]

What are some commercially available probes for salinity (with or without conductivity) that are compatible with the Mayfly data logger?

I’m looking for a good resource on how stream conductivity depends on the nature of the underlying geology.
