GPI - Great Plains Industries Flomec Insertion Meters Data Sheet
PRODUCT CONFIGURATION
DP SERIES INSERTION IMPELLER METERS
FLOMEC® Insertion Meters are cost effective stainless steel meters
for measuring the ow of water, fuels and other low viscosity liquids
in pipe sizes 1.5” – 100” (10 – 2500 mm). Insertion Meters are a
exible, economic method to measure large ow rates with small
pressure drops and low installation costs, with most applications
battery powered with a FLOMEC
totalizer. Applications include HVAC,
hot and cold water, re systems, water distribution (management and
treatment), boiler feed water, waste water and hydrant ow testing.
FEATURES / BENEFITS
• IP68 (NEMA6) submersible 316SS construction (cable
connection only)
• Intrinsically safe option available
• DP525 version suitable for “hot tap” installations
• Quadrature pulse option available for bi-directional ow
measurement
