Beta offer an extensive range of flanged Woltman water meters all offering compact size, low head loss and reliability. Availability of meters is enhanced by Beta's stock of meters with both PN16 flanges and BS 10 table D flanges.   All models feature the ability to change the measuring units in the field without removing the meter from the line.

This range has recently been enhanced by the introduction of the WT-II series of meters that replace the older WT meters.

Our range of flanged water meters is extended by the WST type. This line of meters includes WRAS approved water meters in sizes 2" - 4" and offers all the qualities provided by our standard meters. But for critical applications the use of the latest materials and manufacturing techniques endows them with greater accuracy and an extended operating range between minimum and maximum flow.

For process control, BMS, datalogging and remote display applications these all Arad meters can be supplied with an electrical output. Various options are available but the most common is a reed switch output with a choice of K factor of between 10 litres and 10,000 litres per pulse depending on meter size.

WST Series Turbo Meters

In addition to the features offered by Arad's traditional Woltman Turbine meter, the Woltman Silver Turbo (WST) offers:

• WRAS approved (2" to 4") (50mm - 100mm)
• Improved accuracy: The widest accuracy curve known in the market.
• Wider operating range: The minimum flow rate is 35%-58% below the ISO standard for this type of meter and the maximum flowrate is 150%-233% above it.
• Improved bearings and materials in the WST have been used so that durability far exceeds those required by ISO standards.

Available Sizes:

• Model WST 2" - 8" (50mm - 200mm).

WT-II Series Turbo Meters

• High accuracy, low loss of head and high immunity against abrasive media in the water due to double magnetic coupling.
• Only one moving part - the impeller - in contact with the water for minimum wear and utmost reliability.
• Tungsten carbide impeller shaft tips & bearings for negligible wear are standard on 10" & 12" and optional on all other sizes, code: HD.
• Magnetically driven sealed registers. Stainless steel/glass encapsulated option is unconditionally guaranteed against fogging.
• Wide selection of dial configurations (3 pointers, central pointer), units of measurements and different options of electrical output.

Available Sizes:

• Model WT-II 2" - 12" (50mm - 300mm).
