Hi Michael,
The beeping setting of the flow meter could not be changed. It has been fixed.
When the flow rate is lower than 1.0LPM or the temp exceeds 55c,
the beeping happens.
The temp also jumps around second to second from 25c to 35c to 2c to 40c and is all over the place.
This is normal because the temp of your system is changing.
What's the liquid data of your loop?
Please send the video to the following email address.
And the receipt for this product, we will check and reply to you.
Thank you.
