M4 - 1/2" meters with mechanical register

The M4 is a low to medium flow range model. It is a compact meter that has the ability to handle a wide range of fluid viscosities with exceptional levels of repeatability and durability.

Features

  • Compact size.
  • Easy to read and operate mechanical register.
  • Flexibility of installation options (e.g. can be mounted horizontally or vertically; no flow conditioning required).
  • Low pressure drop allows for economical pump selection or gravity flow applications.
  • Meter construction enables fast and easy on-site servicing without removal from application.
  • Meter accuracy is verified by a factory calibration check after which an individual metrology report is issued.
  • Meter design minimises the number of wearable and replaceable parts and extends product life.
