HYDRUS BULK

HYDRUS BULK

ULTRASONIC METER

Application

HYDRUS BULK is a static, ultrasonic water meter designed for highly accurate measurement of water. It’s unique design ensures no measurement of air, is insensitive to sedimentation, and allows for long-term stability, even under the most difficult conditions.
