About Water Level, Stage, & Flow Sensors

Water level, stage, or flow can be measured with many types of sensors: pressure transducers, bubblers, shaft encoders, or ultrasonic sensors. The location where you are measuring water level, the accuracy required, and the ease of installation all contribute to determining the best water level sensor for your measurement site.
