product overview

SR50A is a newly developed sensor by Campbell Company that uses ultrasound for distance measurement. It measures changes in water level by measuring the time difference between the emission and return of ultrasound pulses. At the same time, users can equip an additional air temperature sensor for temperature correction to reduce the impact of environmental temperature on sound velocity changes and ensure measurement accuracy. This product has good compatibility with Campbell's CR series data collectors.
