McCrometer, Inc. FLO-DAR Area Velocity Sensor

Whether you’re dealing with high solids content, extreme temperatures, shallow or caustic flows, large man-made channels, or velocities reaching up to 20 ft/s, the FLO-DAR delivers accurate flow data with unmatched consistency. The FLO-DAR® AV Sensor, a Hach Flow solution by McCrometer, is a pioneer in non-contact flow monitoring and sets the industry standard for reliability and accuracy. The brilliance of the FLO-DAR lies in its ability to 'stay out of the flow,' making sensor fouling—and the data loss that comes with it—a thing of the past. Using advanced Doppler radar velocity-sensing technology combined with ultrasonic level sensing, the FLO-DAR revolutionizes open-channel flow monitoring by measuring from above the flow, ensuring precise data collection even in the most challenging conditions. Its non-contact design not only minimizes the need for sensor cleaning and maintenance but also enhances safety by reducing personnel’s contact with the flow during installation and maintenance. In fact, sensor removal or replacement can be done without confined space entry, saving valuable time and reducing operational risks. In the event of a surcharge, where flow levels rise to meet the sensor, the FLO-DAR’s pressure level sensor and optional electromagnetic Surcharge Velocity Sensor ensure that your flow data remains uninterrupted and accurate. This robust design means less maintenance, fewer operational interruptions, and more reliable data for your analysis. With the FLO-DAR, you’re not just investing in a flow meter; you’re investing in peace of mind and long-term performance.
