GPI Flomec QSE Specifications

PRODUCT CONFIGURATION

QSE MAG FLOWMETER

The QSE Mag Series is a dependable highly accurate
electromagnetic owmeter designed for ow and usage
monitoring in commercial applications.

The NorylTM housing and ow tube offer a lightweight, easy­to-install Mag Meter that is resistant to heat (210°F [99°C])
and compatible with many water-based liquid solutions.

The QSE Mag Meter monitors ow rate and total ow in a
wide variety of applications including: HVAC, Turf/ Irrigation
and other water reclamation applications.

FEATURES / BENEFITS

• Low investment and operating costs

• ± 0.5% Accuracy of Reading (from 0.25 fps to 15 fps
[0.08 to 4.6 m/s])

• Wide turndown ratio of 60:1

• Non-intrusive, no moving parts to wear out,
maintenance, repair costs low and tolerates high flows
without damage

• The slightly modified bore permits unobstructed flow
and minimizes flow disturbances and straight pipe
requirements
