Using advanced digital Doppler radar velocity- sensing technology, along with ultrasonic level-sensing, the FLO-DAR® AV Sensor from Hach revolutionizes open-channel flow monitoring by measuring from above the flow. This means it can more effectively provide highly accurate flow data under a wide range of challenging flow and site conditions, including sensor disturbances, high solids content, high temperature, shallow and caustic flows, large man-made channels, and high velocities of up to 20 ft/s. Also, for those times when a surcharge event does raise the flow to sensor level, the FLO-DAR's pressure level sensor and optional electromagnetic Surcharge Velocity Sensor will continue to provide uninterrupted and accurate flow data.
