OMEGA’s multi-tube variable area
flow meter are convenient for
applications where up to six streams
of liquids or gases are to be
metered in individual channels. Flow
pattern B represents multiple inlets
manifolded into one outlet (see
diagram). To obtain one inlet split off
into multiple outlets, flow pattern B
can be turned upside down and the
flow tubes inverted in the field. The
variable area flow meter end fittings
can be supplied in aluminum or 316
SS. Precision metering valves with
16 turn non-rising stems are also
available (consult Sales).

Comes complete with air and water correlation sheet for each tube.
Delivery time depends on configuration.
Select the desired 150 mm flow tube from those listed on online. Delete the
*
FLT-prefix and insert the remaining suffix from the flow tube into the model numbers above.
Add the price of the flow tubes to the price of the frame.
For NIST calibration, add suffix “-NIST AIR” or suffix “-NIST WATER” to model number,
for additional cost.
Ordering Example: FL-3SA-45G-61G-61C calls out a three tube meter with 316 SS end
fittings, independent inlets and outlets with the FLT-45G, FLT-61G and FLT-61C 150 mm flow
tubes installed in the unit.
