The M7 is a specialised meter for aggressive chemicals and water based products. It has the ability to handle a wide range of fluid viscosities with exceptional levels of repeatability and durability
Features
- Compact size.
- Two independent pulse units.
- 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 design minimises the number of wearable and replaceable parts and extends product life.
- Meter accuracy is verified by factory calibration check after which an individual metrology report is issued.
- LCD & Pulse Version have IP65/NEMA9 protection.
