RK120-07 The wind speed and direction meter is a kind of measuring instrument which uses the time difference of ultrasonic wave in the air to measure the wind speed and direction. RK120-07 uses low-power chip with power consumption of only 0.2W, which is especially suitable for solar or battery powered environment with high power consumption requirements. Due to the adoption of new technology and new process, the structure is more compact and compact. Optional temperature and air pressure module.

①When there are only two parameters of wind speed and wind direction, 4-20mA output can be selected.
MOUNTING & DIMENSION
For indoor use, the sensor can be used at any where .Directional installation to measure wind speed on different planes.
Step1:
Positioning: generally, RK120-07 is installed in a vertical installation pipe .ensure the measurement on the same level.
Step2:
There is rotary adjustable mounting holes at the bottom of the senor,when mounting the sensor, to ensure the indicator on on the sensor comply with the geographic north.
Step3:
Installation: the installation pipe needs 3 equally spaced holes, tapping M5 screws, position7.5mm from the top of the pipe.
