Series MM Mini-Master® Flowmeter
|
|
Used to indicate or Manually Control
Air or Water
|
|
|
|
Offering advanced features at low cost, the 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 front 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 MMA flowmeter with a low
profile or
|
|
flat front surface where no valve is required.
|
|
|
|
The MMA is practically unbreakable, mounts easily, and is
easy to read. Two 5/16" OD 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 MMA 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 1/4" OD 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 MMF flowmeter an excellent value at its low cost.
