Can log level and velocity data for more than 60 days without changing a battery. Includes 1 Submerged AV Sensor with 25 ft of cable. Review Overview and Details for more information.
The compact and lightweight Sigma 910 Portable Area Velocity Flow Meter measures average velocity directly, without the need for time-consuming and costly flow profiling. Hach’s exclusive Submersible Area Velocity Sensor assures accuracy and reliability for unsurpassed versatility, even in the harshest open-channel applications.
The 910 Flow Meter is NEMA 6P sealed to withstand submergence and prolonged surcharge conditions. Its compact size makes it easily portable and provides for easy storage and fit in a variety of applications such as sewer and storm water monitoring.
The technology used in the Sigma 910 flow meter automatically corrects for temperature effects on depth measurement for a higher level of accuracy. The patented* “Drawdown Correction” feature corrects the effects of velocity on accurate depth measurement. Advanced,
ultrasonic one-MHz Doppler technology avoids signal dropouts and ensures high levels of accuracy in low-flow, full-pipe, or reversed-flow conditions. The hydrodynamic body and side-mounted cable also maintains accuracy by reducing turbulence along the sensor body.
*Patent number U55691914
The 4.5-inch diameter of the Sigma 910 flow meter means it can be installed almost anywhere. It has a low profile for reduced maintenance. The low maintenance sensor is detachable and interchangeable for flexibility. An oil-filled probe greatly reduces sensor fouling and need for regular cleaning schedules. Single point calibration (atmospheric) makes calibration quick and accurate.
The Sigma 910 Portable Area Velocity Flow Meter is ideal for short-term flow studies and sanitary sewer evaluation studies.
