Overview<\/h2>\n\n\n\n

Solinst now offers an optional, field-replaceable unscreened nose cone design for the Levelogger<\/a> (M5 models\u2014Junior <\/a>and LevelVent<\/a> included). This enhancement is the result of customer feedback and field collaboration with Saso Consulting, who provided valuable insight from real-world monitoring in shallow, aerated streams \u2014a special thank you to Paul Saso.<\/p>\n\n\n

Note:<\/strong> As this nose cone design lacks a filter screen, care should be taken when deploying the datalogger.<\/p>\n\n\n\n

Key Improvements<\/h2>\n\n\n\n

Enhanced Bubble Release:<\/h3>\n\n\n\n

The redesigned nose cone geometry allows air bubbles to escape more easily from the sensor area, preventing them from becoming trapped near the pressure transducer.<\/p>\n\n\n\n

Maintaining Data Accuracy:<\/h3>\n\n\n\n

Trapped air bubbles can introduce potential variability by acting as a compressible medium. This variability can be amplified by diurnal temperature changes*, which may lead to noise or drift in pressure and level readings. The new design reduces this effect, helping to maintain the accuracy and stability you expect from Leveloggers.<\/p>\n\n\n\n
