LevelVent Models are rated to a specific submergence depth (Table 1). The choice of model depends on the accuracy of the level required and the submergence depth. Most important, your selection should be based on the maximum anticipated water level fluctuation.
|LevelVent Models||Submergence Depth||Accuracy|
|M5||5 m (16.4 ft.)||± 0.3 cm (0.010 ft.)|
|M10||10 m (32.8 ft.)||± 0.5 cm (0.016 ft.)|
|M20||20 m (65.6 ft.)||± 1 cm (0.032 ft.)|
Table 1 - LevelVent Ranges
The LevelVent logger can withstand overpressurization of 2 times the intended range, e.g. a Model M10 can accommodate a fluctuation of 20 meters or 60 feet and still record pressure. However, over-range accuracy is not guaranteed.
