SENSOR
Velocity Measurement
Method: Electromagnetic (Faraday’s Law)
Range: -5 to +20 feet per second (-1.5 to
+6.1m/s)
Accuracy: ±2% of reading, ± 0.05 zero
stability at 0 to +10 ft/sec (0 to + 3m/sec)
Zero Stability: ±0.05 feet per second
(±0.015m/sec)
Resolution: 0.01 feet per second (±
0.003m/sec)
Level Measurement
Method: Submerged pressure transducer
Range: Standard 0.4 to 138 inches. (10mm to
3.5m) Optional 0.4 to 276 inches
Accuracy: ±1% of reading
Zero Stability: ± 0.03 ft. (± 0.009m) zero
stability for 0 to 10 ft (0 to 3m). Includes non-linearity, hysteresis and
velocity effects.
Resolution: 0.1 inch (2.5mm)
Over Range Protection: 2 X range
Flow Measurement
Method: Conversion of water level and pipe
size to fluid area. Conversion of local velocity reading to mean velocity.
Multiplication of fluid area by mean velocity to equal flow rate.
Conversion Accuracy: ±5.0% of reading.
Assumes pipe is 10 to 90% full and with a level greater than 2 inches
