MMA-X MMA-X-LV MMF-X

The Series MM Mini-Master® Flowmeters consists of two series of owmeters suitable for both gas and liquid applications with advanced features at a low cost.

The Series MMA is a 2˝ (51 mm) scale owmeter that is user congurable with or

without non-removable top or bottom front mounted metering valves. It is constructed from transparent nylon material providing high chemical resistance and is easily

disassembled via the provided key for cleaning or reconguration. The Series MMF is a 1-1/2˝ (38 mm) scale compact owmeter ideal for measuring

small volume air. It features bezel type mounting that can be quickly installed from the front of the instrument panel.

FEATURES/BENEFITS

• Low installation costs with easy mounting

• Long operation life with durable construction

• Precision molding enables high repeatability

• White back on the ow tube allows for better visibility of the oat increasing reading

accuracy

• Side printed scale graduations allows for instantaneous ow reading saving time

• Compact bodies require minimal panel space freeing valuable space

APPLICATIONS

• Medical equipment

• Air samplers

• Gas analyzers

• Pollution monitors

• Chemical injectors

• Cabinet purging
