TB0.5L/70 & TB1L/70 Dual Tipping Bucket Flow Gauge

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.
