HyQuest Solutions’ current meter counter CMCbt is a small electronic device for collecting the count (and time) from almost any mechanically rotating current meter. It provides a Bluetooth interface between the current meter and a user interface such as the HydroTab Application. 

The CMCbt counts the rotations and transmits the data to an external tablet where the velocity and discharge can be calculated. It is also used to totalize the number of tips in a tipping bucket rain gauge (TBRG).

The CMCbt has three LEDs and an audible sounder to indicate its status and the counts.  

The CMCbt offers connectivity between the current meter and a tablet via Bluetooth. It can be mounted directly onto a top-setting wading rod. Faulty connections are detected. All settings and operations are performed via the Bluetooth interface.

  • Small and compact
  • Self-calibrating, no adjustment or calibration is required
  • 100 % waterproof
  • Used in conjunction with HydroTab application on Samsung Active Tab for current meters
  • Used in conjunction with the FCD App on Samsung Active Tab or Android Smart Phone for performing field calibration checks of tipping bucket rain gauges.

The CMCbt is especially suitable for

  • Hydrology
  • Flow Velocity Measurement
  • Discharge Calculation (e.g. with HydroTab, see flipside)
  • Small and big water courses
  • Open channels
