• 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
