Model 801 Flat Flow Meter
The Model 801 Electromagnetic Flow Meters measure the speed of water in Open Channel environments with exceptional accuracy.
The Model 801 Electromagnetic Flow Meters measure the speed of water in Open Channel environments with exceptional accuracy.
The small sampling volume of the flat sensor makes it suitable for shallow flows, or measurements in confined spaces.

Technical Specifications
Model 801 - Flat Type
Data Acquisition
The Model 801 Flow Meter is supplied with a dedicated Control Display Unit that both drives the sensor and provides data display of the measured water velocity. Data is updated at 1 Hz, and may be averaged over any number of seconds from 1 to 600. The display will show real-time speed data at a resolution of 1mm/s, as well as the result of the data average, and a Standard Deviation figure to give added data confidence. A solid state memory records all results (up to 999 averaged readings), and the data may be downloaded to PC using
the RS232 interface lead supplied.
Calibration
The Model 801 is calibrated at Valeport’s own premises up to speeds of 1 m/s. Higher speed measurements are based on linear extrapolation. Specific high speed calibrations can be arranged at a third party facility on request.
Control Display Unit
-5°C to + 40°C (sensor)
Configuration
Available for use as hand held “Wading Sets” only, with the operator standing in the channel, holding the instrument in position. The system is supplied with 1.5m wading rod (3x 0.5m sections), graduated in cm, and a 3m cable from instrument to display unit.
Alternatively, a “top-setting” wading rod system is available, which allows the vertical position of the instrument to be set without removing the wading rods from the water.
Software
System is supplied with CDU Express Windows-based PC software, for data extraction from the display unit. CDU Express is licence free.
