Flow measurement
Intrinsically safe area velocity flow meter, 2150EX
Area velocity flow meter approved by Baseefa (ATEX) and CSA (Class I, Division 1) for potentially explosive atmospheres such as manholes, digesters and storage tanks.
- All-digital smart probe, factory-calibrated for temperature and a 3 m span
- Rugged, submersible IP68 (NEMA 4X, 6P) enclosure
- Software updates without removing the meter from the hazardous area
- RS232EX isolator cable for safe laptop connection in the field
- Measures velocity in flows down to 25 mm deep
- Applications: open-channel flow in hazardous locations, inflow and infiltration and sewer overflow studies
