Portable Area Velocity Flow Meter with 1 Submersible Area Velocity Sensor

The Sigma 910AV measures average velocity directly without the need for time consuming flow profiling, significantly reducing the cost of installation and operation. With a compact 4 1/2 x 18" design, weighing less than 8 lbs (with battery), the 910AV is one of your best options for remote environments. This meter will log level and velocity data for more than 30 days without changing a battery, and its sealed design provides superior system protection against surcharge conditions.

• Low-profile probe reduces maintenance and is detachable/interchangeable for ultimate flexibility.
• Easy installation with a small, 4½ in. diameter and no velocity calibration required.
• NEMA 6P sealed to withstand submergence and prolonged surcharge conditions.

• Advanced, ultrasonic on-MHz Doppler technology avoids signal dropouts and ensures, without the need for on-site calibration, high levels of accuracy in low-flow, full-pipe, or reversed-flow conditions.
• A higher level of accuracy, since the 910 Portable Area Velocity Flow Meter automatically corrects the effects of temperature on level measurement.
• Patented `Drawdown Correction´ feature corrects the effects of velocity on accurate level measurement.
