FM 900 OPEN CHANNEL FLOW MEASUREMENT SYSTEM
Non-Contact Flow Monitoring for all flumes and weirs


The FM 900 provides accurate non-contact ultrasonic open channel flow measurement.
Simple programming allows selection from a list of common built-in weir and flume tables. In addition,
head vs. flow data points may be input for almost any type of primary device.

The integral display and keypad allows for fast, simple programming and operational indication.
A real time clock and datalogging capabilities allow up to 6 months of flow information to be
stored in memory.

Adjustable damping, transducer transmit power, and low flow cutout provide flexibility in difficult
monitoring applications.
