Description

The SRZ-H High Resolution Helical PD Flow Meters are ideal for highly filled and abrasive fluids, such as polyurethanes and polymers, glues and sealing materials, as well as heavy fuel oils. These positive displacement flow meters are equipped with a built in sensor and are capable of maintaining consistent accuracy of ±0.5% despite changing viscosity conditions.

Practical applications include:

  • Sealant and adhesive dispensing applications
  • Paint reclaim and environmental tracking
  • Paint circulation and supply
