AW Flow Meters offers two specialized helical gear flow meters, SRZ-STAT for high resolution and SRZ-HR for ultra high resolution.  These meters are suitable for a variety of industrial applications, including:

  • Sealant / Adhesive Dispensing Applications – Single and Multi-Component
  • Paint Reclaim and Environmental Tracking
  • Paint Circulation / Supply
  • Paint Spray Operations-High Solids / Filled Materials
  • Material Manufacturing – Monitoring / Batching
  • Full body resin applications
  • Affordable and Accurate: This meter has the ability to maintain consistent accuracy despite changing viscosity conditions, with accuracy of ±0.5% of reading.
  • Rugged Construction/High Pressure: The SRZ’s solid meter construction is made of 303 stainless steel with tungsten carbide bearings for corrosion resistance and durability. Optional hardcoat gear offerings available.
  • Flexible: May be used with a wide range of materials and viscosities with a low pressure drop than conventional meters and wide flow range/size selection. Models now offered in both NPT and BSPP threaded ports.
  • Proven Reliability & Performance: With a proven industry record for reliable meter life and electronics, these meters now offered in a low profile design with integrated sensor technology.
