TB6/40 Tipping Bucket Flow Gauge

KISTERS’ tipping bucket flow gauge TB6/40 Series II is used for measuring water flow coming out of a pipe or a drain. The unit comes with a dual reed switch, thus, when connected to a KISTERS’ data logger flow data can be logged and collected manually when required. In addition, the flow gauge can be telemetered by connecting to a ML-IoT device or to a 3G/4G data logger. The only routine maintenance required for the flow gauge is cleaning.

The TB6/40 flow gauge operates on the tipping bucket principle. A receiver of 200 mm diameter collects the water which is strained by a gauze filter before being passed to the tipping bucket measuring system. Tips of the bucket occur with each 40 millilitres of water collected. A reed switch detects these events and produces a momentary contact closure signal for connection to a data logger (e.g iRIS logger or IoT device).

A fully sealed dual reed switch assembly with varistor protection is provided for several reasons:

• Two isolated switches permit the control of two separate circuits; e.g. a local counter and a telemetry circuit.
• Parallel connection of both switches increases the current carrying capacity of the contact system if required.
• Parallel switch operation confers a degree of redundancy in locations where data from the flow gauge is critical to flood warning etc.

All gauges have been calibrated by KISTERS prior to despatch.
