HyQuest Solutions’ dual tipping bucket flow gauge TBL-70 is used for measuring water seepage coming out of a pipe or a drain. The unit is equipped with two distinct buckets to provide best accuracy over a large range of flows: a smaller bucket at the top of the gauge to measure at low flows and a larger one at the bottom to measure at high flows. Each bucket is connected to its own dual reed switch effectively enabling redundant data acquisition in two distinct data loggers, or providing data to two devices (e.g. a data logger and a counting display), etc.

Operation

The two buckets operate simultaneously up to 6 L/minute. At low flows where the large bucket is not full to tip, more accurate results can be obtained from the small bucket’s reed switch output. At higher flows above 6 L/minute the smaller bucket at the top has to be removed by the user. Data is then generated solely by the larger bucket’s reed switch output.

  • Non-corrosive materials

  • Suitable for harsh environment

  • Accurate readings at low and high flows

  • 4 x M8 mounting brackets

  • Easily cleaned and little maintenance needed

     

The TBL-70 is suitable for all applications where a water flow out of a pipe or similar outlet needs to be supervised. This may include

  • Monitoring at basin outlets of any kind of industrial water, grey water or storm water retention basins
  • Sewer network injections into a collection basin
  • Drain output
  • Water discharge out of a treatment or intermittent storage basin
  • Pump testing
