Flow measurement
Area velocity flow module, 2150
Continuous-wave Doppler area velocity flow meter for portable flow surveys and permanent sites; the smart probe digitises level in the sensor and is factory-calibrated, so span recalibration is never needed.
- Rugged, submersible NEMA 4X, 6P (IP68) enclosure
- Chemically resistant epoxy-encapsulated sensor resists oil and grease fouling
- Replaceable internal desiccant cartridge and hydrophobic filter
- Quick-connect sensor interchangeable in the field without recalibration
- Up to four 2100 Series modules networked by stacking or extension cables
- Measures velocity in flows down to 25 mm deep
- Applications: portable and permanent AV flow monitoring for inflow and infiltration, capacity assessment and sewer overflow studies
