Flo-Tote^TM 3 Portable Electromagnetic Flowmeter for Open Channel Flow Measurement

Building on the success of thousands of installations worldwide we are pleased to introduce the Flo-Tote 3 - the new generation of the world's most popular sewer flowmeter.

Marsh-McBirney's Flo-Tote 3 portable flowmeters are based on the original and unsurpassed velocity/area measurement sensors and techniques. Continuous product innovation has made it possible to combine proven sensor design with state-of-the art technology for open channel flow.

In addition to the accuracy and ease-of-use our customers have come to expect, the Flo-Tote 3 offers some exciting new features:

• Disconnectable sensor for quick and easy replacement
• Interchangeable with Flo-Dar sensors
• Room to store more data with a storage capacity increased to 64K
• Extended battery life
• Pocket PC compatible for data collection convenience

Accuracy is Important!

Unlike Acoustic Doppler meters, the Marsh-McBirney electromagnetic area/velocity flowmeters measure both velocity and level in the same cross-section (or slice of pipe), a requirement necessary for accurate flow rate measurement using the continuity equation:

Q = V x A.

Using measurements derived empirically over ten years, MMI has bridged the gap between the performance of its velocity sensor in a tow tank and its ability to calculate the average velocity that exists in an open channel sewer pipe.

The flow accuracy of the Flo-Tote 3 is based upon the accurate measures of both velocity and level in hydraulic flow labs, as well as under actual sewer conditions in the field.

Flow measurement is based on the equation:

Q = V x A where

The measurement of both velocity and level in the same cross-section of pipe is critical for accurate flow rate determination.
