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.

• Non-corrosive materials
• Suitable for harsh environments
• Accurate readings
• Fast and easy cleaning
• Low maintenance
• Outer enclosure keyed to enable the release of the outer enclosure without the need for the removal of the three securing screws
• Insect covers: In-built mesh in the base and stainless steel mesh on the enclosure covering all openings to prevent insects and ants entering gauge
• Robust

The TB6/40 is suitable for all applications where water flow out of a pipe or similar outlet needs to be monitored. Typical situations 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 to or from a tailings dam
• Water discharge out of a treatment or intermittent storage basin
• Pump testing
