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.

Non-Contact Flow Monitoring for all flumes and weirs Choose from the FM1000D remote mounted LCD indicator or the FM1000C chart recorder with vacuum flourescent display.
The system totalizes and computes flow for a wide variety of primary devices. Both systems include the field-proven FM-1000US Ultrasonic Level/Flow Sensor.
