F-1000 Series Turbine Flow Meters
ONICON’s F-1000 Series is a family of insertion and inline style turbine meters flow meters that provide accurate, reliable flow measurement in a variety of applications. The F-1000 Series meters are suitable for use in pipes ranging in size from ¾ to 72” in diameter. Each model utilizes ONICON’s patented electronic turbine rotation sensing system and unique low mass turbine design that is accurate over wide flow ranges with excellent low flow measurement capability.
THREE DIFFERENT STYLES
•F-1100 single turbine insertion meters Suitable for use in 1¼ – 72” pipes
•F-1200 dual turbine insertion meters Suitable for use in 2½ – 72” pipes
•F-11XX single turbine inline meters Available as ¾ and 1” meters.
APPLICATIONS
•Chilled water or hot water & water/glycol solutions for HVAC
•Domestic/municipal water
•Clean process water
