We want connect the ultrasonic anemometer 2D at CR1000, but I don’t have idea.
We have also SDM-SIO1 in house, Can you help me?

Uluna,

It looks like this sensor is capable of outputting a 4-20mA signal for velocity, direction and temperature. The CR1000 can measure these signals using a shunt or CURS100 module to convert the current signal to a voltage.

Then in the CR1000's program you will need a function that takes the measured signal and applies a multiplier and offset (assuming its linear) to calculate engineering unit such as meters per second.
