HyQuest Solutions’ single tipping bucket flow gauges TB0.5L and TB1L are used for measuring water seepage coming out of a pipe or a drain. In both models the 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. TB0.5L and TB1L are perfectly suitable for flow measurements in water carrying sediments or iron hydroxide deposition. Made of platsics and coated steel, these devices are both robust and fast and easy to clean. The bucket tips when it is filled to maximum. The magnet integrated into the bucket rearside slides along the reed switch mounted in the flow gauge’s frame. The magnetic field forces a contact closure in the reed switch. The latter can be recorded by one or two connected data loggers. The number of tips per time unit is a measure of the flow rate.
