Flow measurement |
|
Technique | Cross-path ultrasonic transit-time |
Measurement resolution | 100 picoseconds |
Measurement rate | 1.5 seconds |
Accuracy | ±2.5% verified in Rubicon’s hydraulics laboratory under fully submerged conditions measured between flow ranges of 0.5ML/d to 27.5ML/d for the PM-450 models and between flow range of 0.25ML/d to 12.0ML/d for the PM-300 models. |
Measurement range | Accuracy listed above is achieved at flow velocities greater than 30mm per second. Maximum flow capacity is determined by site hydraulic conditions, but is typically greater than 2m per second. Consult your Rubicon sales engineer for details. |
Sensor quantity | Flow measurement provided by 20 ultrasonic transducers across 5 planes of measurement. An additional downward-facing transducer monitors pipe-full status. |
Calibration method | Factory pre-calibrated. Simple in-field verification process |
Alarming | Meter alarms if water depth falls below minimum required level, when optional water level sensor is installed. |
