Just in from Ecowitt
HI, Trent
The main upgrade is done from two side:
1. Metal net was changed to round type with underneath water flow tunnel added. This made the sensor robust to rain, and it will solve high wind speed read issue.
2. We have a silicon rubber standing near the ultrasonic sensor, and this can guide the water to be bypassed rather than sitting on the sensor, which can lead to no data measurement problem at windy + heavy rain condition.
Here are the main changes done to this design. It will be a more stable design against Tempest or another competitor’s model.
Super glad they have made improvements, I guess I will report any findings when I receive it.
Sounds like a change in design to better manage water flow away from the ultrasonic sensor.
I’ll post photos when it arrives and someone might be able to send a photo of there’s so we can compare the 2 designs.
