Is there a way to use a RM Young Anemometer without Davis 6336
« on: October 13, 2021, 06:37:29 PM »
I am looking at anemometer options for VP2 and read that with the Davis 6336 which is discontinued :( there is option to use RM Young.

With the 6336 discontinued is there a way to do this, or do I need to watch for and hope a 6336 becomes available at some point?

Thanks

Going to be hard pressed to find a 6336

Following link has some discussion re an RM Young interface board.

Other than that then there are quite a few Davis compatible Ultrasonic options out there now including Davis's own Ultrasonic

As an aside (I can see the OP is really asking about RM Young), the Davis ultrasonic is actually the French LCJ Davis-compatible one (slightly modified at Davis's request AIUI, simply for easier maintenance, ie battery replacement). We've had the LCJ ultrasonic one available for purchase for some time, eg 5 years IIRC so there is some decent experience with it.

That's the thing with no convenient interface availability for the RM Young it tends to make it not a viable option anymore hence the suggestion to maybe look to Ultrasonic, it's not the cheapest option but there is certainly several to check out besides the Davis version which does have some limitations depending on the installation.

Thanks guys. Can you send some info on the alternate options to the Davis ultrasonic one?

I live in NY, and am thinking about ultrasonic in the future to help catch some low wind and to compare to the Davis 6410 cups anemometer for curiosity.

Mention NY as for few months cold and snow may need to be considered in what one to get, but as I said would be 2ndary to the Davis 6410 cups anemometer.

Thanks as look to learn more about ultrasonic options

Have tried the following VP2 compatible ultrasonic, Darrera is not a cheap option, Hongyuv has a better power supply arrangement

Calypso Instruments make one but untried. One issue I have with the Davis 6415 is the "in-built factory batteries"

I am running the Davis ultrasonic mounted on the ground tripod that holds the ISS. I wanted to see the correlation of rain vs. wind speed and direction.

Here is a link to my page, scroll down a bit for the ultrasonic. I have some comparison charts as well.

Thanks for sharing the comparisons.
Looks like close correlation of data, with sonic a bit more responsive at low speeds.

How does the sonic one do in the cold/winter as see you are in Michigan?

Thanks
Frank

Last winter it ran without any problems.
