WST Series Water Meters

WST

WST 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. Available in 3″, 4″, 6″, 8″, 10″ and 12″ sizes.

Why WST

mpeller 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.

Product Advantages

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.
3″-8″ 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
