 Offering
advanced features at low cost, the Dwyer Series MM flowmeters are
ideal for a wide range of OEM and user application in medical equipment,
air samplers, gas analyzers, pollution monitors, chemical injectors,
cabinet purging, etc.
The
standard Model MMA flowmeter is suitable for both gas and liquid
applications. It can be configured by the user with the parts provided
to have non-removable top or bottom from mounted metering valves
or no valve at all. The transparent nylon material provides high
chemical resistance, low moisture absorption and is transparent
to facilitate routine inspection. Using the assembly key provided,
the flowmeter can be disassembled anytime for cleaning or reconfiguration.
In OEM quantities, ultrasonically welded caps or interchangeable
mole cores enable production of the Mini-Master® A flowmeter with
a low profile or flat front surface where no valve is required.
The
Mini Master® A is practically unbreakable, mounts easily, and is
easy to read. Two 5/16" O.D. mounting-connection tubes permit quick
push-on connection of rubber or plastic tubing. A bottom clip for
"stand up" mounting is also provided.
Despite
its compactness, the Mini-Master® A flowmeter features a 2" scales
which combined with precision molding, enables highly repeatable
readings to be made to within ±4% accuracy.
Where
a compact flowmeter is required to measure small volume air flows,
the Model MMF is recommended. Easy to mount, they require a minimum
of panel space. A white back on the flow tube makes the ball float
easy to see. The scale is highly visible and easy to read. Scale
graduations are printed on aluminum alongside the flow tube (not
on it), so the position of ball float is instantly visible.
The
Model MMF's bezel type mounting is modern, attractive and quickly
installed from the font of instrument panel. Two ¼" O.D. mounting-connection
tubes are integrally molded with flowmeter body. They can be back
connected to flexible rubber or plastic tubing and held in place
with two spring retainers which are furnished. If preferred, connections
may be made to metal or rigid plastic tubing with a double compression
fitting or nylon tube union such as Dwyer Part No. A-328.
Excellent
repeatability and ±10% accuracy make the Mini-Master® F flowmeter
an excellent value at its low cost.

Model
MMF mounts easily from front of panel. Drill two 9/32" or 5/16"
diameter holes in panel on 2 1/16" centers. Insert mounting
connector spuds. From rear, slide on the two spring retainers
(furnished) and push on rubber or plastic tubing.
Model
MMF connections. Connector at top, installed in panel, has retainer
and flexible tubing in place. Connector at bottom shows alternative
connection with metal or rigid plastic tubing, using a double
compression nylon tube union (as Dwyer Part No. A-328).
