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. |

FM-1000
OPEN CHANNEL FLOW MEASUREMENT SYSTEM
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.
