M1 - 1/4" pulse meters

The M1 is a small capacity meter 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.
Meter accuracy is verified by a factory calibration check after which an individual metrology report is issued.
Solid state Hall Effect Sensor/Reed Combination.
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.
Has IP54/NEMA13 protection. MISSPH-XY IP65-NEMA 9
Flexibility of installation options (e.g. can be mounted horizontally or vertically; no flow conditioning required).
