WST and WT Series Water Meters

WST Series Water Meter

WST and WT Water Meters use a double magnetic transmission to drive the register and this unique design enables the meter to handle high loads of sand since only the impeller is in contact with the water. Transmission gears are located in a sealed, dry compartment which has no contact with the water. The impeller, located in the center of the flow, allows for very accurate measurements over a wide range of flows. Built-in straightening vanes in the WST meters reduce the length of straight pipe required before and after the meter. Available in 3", 4", 6" and 8" sizes for the WST and 10" and 12" sizes for the WT models.

Product Advantages

  • Impeller is located in the center of the flow allowing for accurate measurements (±2%) over a wide range of flows - including low flows.
  • Double magnetic transmission (repelling magnets) drives the register enabling the meter to handle high loads of sand since only the impeller is in contact with the water.
  • Transmission gears are located in a sealed, dry compartment which has no contact with the water.
  • Balanced impeller with equal load on front and rear gears prevents bearing wear and maintains high accuracy even after years of operation.
  • Registers are stainless steel encapsulated and guaranteed not to accumulate moisture or fog.
  • 'WST' Water Meters have built-in straightening vanes which reduce the length of straight pipe required before and after the meter.
  • Wide selection of register options.

Applications

  • For main supply lines in agriculture applications

WST and WT Water Meters Installation

Installation Requirements

  • The meter may be installed in any position. For non-horizontal positions, the flow should be upwards
  • Straight pipe installation requirements for 'WST' meters: 5 x diameter pipe upstream (before the meter) and 2 x diameter pipe downstream (after the meter)
  • Straight pipe installation requirement for 'WT' meters: 10 x diameter pipe upstream (before the meter) and 5 x diameter pipe downstream (after the meter)
  • Prior to installation of the meter, the pipeline should be thoroughly flushed.
  • To eliminate air in the system, continuous acting air vents of proper size and type are required
