FlowTracker2 with optional pressure sensor

Collect Level and Depth Data with FlowTracker2 Optional Pressure Sensor Feature!

SonTek is pleased to unveil the new FlowTracker2 now with optional pressure sensor feature! This new feature allows for:

  • More accurate and precise measure of depth
  • More accurate and precise positioning of sensor at proper depth for measurement
  • Ability to measure in places where sight-reading of depth on a rod is inconvenient or impossible
  • Elimination of chance of human error when depth is manually read on the rod (source of error) and then keyed-in (another source of error).
  • Ability to review and QA/QC depth time series data back at the office.
  • SonTek’s innovative patent-pending method of properly compensating pressure readings under different flow conditions.
