WM40 - 1 1/2" pulse meters

The WM40 is the medium to large capacity meter in the WM-SERIES™ range. 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 which can be linked to allow doubling of the pulse output.
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 a factory calibration check after which an individual metrology report is issued.
Both LC Displays meets European CE directive fot EMC.
Deluxe/Standard Displays and Pulse Version have IP65/NEMA9 protection.
Intrinsically safe LC Deluxe & Standard Displays. Certificate of conformity number PTB Nr. Ex-93.C.4033x & KEMA O5ATEX1168X
Pulse Versions have Flameproof Certification. AUS Ex2377x
