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.
