Performance
Specs
Flow Accuracy:
± 1% of reading ± 0.2 % of full scale*
* Point velocity for insertion flowmeters. Fox recommends a
minimum of 15 diameters of straight pipe upstream of the flowmeter
and 10 diameters downstream for insertion flowmeters. Fox
recommends a minimum of 8 diameters of straight pipe upstream of
the flowmeter and 4 diameters downstream for inline
flowmeters.
Flow Repeatability:
± 0.2% of full scale
Flow Response Time:
0.9 seconds (one time constant)
Temperature Accuracy:
± 1.8° F (± 1.0° C) over -40 to 250° F (-40 to 121° C); ± 3.6° F
(± 2.0° C) over 250 to 650° F (121 to 343° C). Minimum velocity 60
