Notes: (1) Accuracies stated are for the total volumetric flow through the
pipe.
(2) Nominal rangeability is stated. Precise rangeability depends on
fluid
and pipe size.
Repeatability 0.1% of rate.
Response Time Adjustable from 1 to 100 seconds.
Material Compatibility Series 220 In-Line Flow Meter:
Any gas, liquid or steam compatible with 316L stainless steel, C276
hastelloy or A105 carbon steel. Not recommended for multi-phase flu-
ids.
Series 221 Insertion Flow Meter:
Any gas, liquid or steam compatible with 316L stainless steel. Not
recommended for multi-phase fluids.
Flow rates Typical volumetric flow ranges are given in the following tables. Precise
flow range depends on the fluid and pipe size. 221 insertion meters are
applicable to pipe sizes from 2 inch and above. Consult factory for siz-
ing program.
