M2 - 1/4" pulse meters

Download brochure

The M2 is one of the small capacity meters in the M-SERIES™ range and is differentiated by its flow rate capabilities. It has the ability to handle a wide range of fluid viscosities with exceptional levels of repeatability and durability.

Features:

Very compact size.
Low flow capability with high resolution output.
Solid state Hall Effect Sensor/Reed Switch Combination.
Has IP54/NEMA13 protection. (M2SSPH-XY IP65/NEMA9)
Flexibility of installation options (e.g. can be mounted horizontally or vertically; no flow conditioning required).
Meter accuracy is verified by a factory calibration check after which an individual metrology report is issued.
Low pressure drop allows for economical pump selection or gravity flow applications.
Meter design minimises the number of wearable and replaceable parts and extends product life.
