Water Meters

Water meters track potable, process and wastewater use for billing, sub-metering and conservation. Accurate metering reveals leaks and helps control costs.

Water Meter Types

  • Positive displacement meters – accurate at low flows
  • Multi-jet and single-jet meters – commercial service
  • Turbine meters – higher flows
  • Mag meters – no moving parts
  • Pulse and AMR outputs – remote reading

Choosing a Meter

Select by pipe size, flow range and output. Potable water requires lead-free meters.

Nisco supplies water meters for commercial and industrial use.
