MAZZEI F-30 FLOWMETER
Molded of polycarbonate with a #316 stainless steel
float and set point indicator. Available for in-line
installations, and made to the same high standards
expected of all Mazzei products.
Features
•
Recommended for use with ½-inch and ¾-inch Mazzei Injector
models.
•
Connections: ¼-inch Barb/MNPT
•
Scale – Water Flow Range: 10-150 LPH or 5-40 GPH
•
Dual Scale for Liquid Flow
Optional Suction Assembly Kits are
available for industrial and agricultural
applications. In addition, there are Flow
Control Valves that enable customers to
easily adjust liquid suction flow rate.
MAZZEI MV-5 METERING VALVE
The MV-5 is a step up in metering valves. It’s
engineered to provide increased meter control
through all valve positions due to its unique “V-Port”
design. You can control flows more precisely and
accurately. Its male threaded fitting offers easy
installation and maintenance. Available in UV
resistant Polypropylene or FDA approved natural
PVDF. The MV-5 is designed for chemical feed in ag
or industrial applications

TECHNOLOGY
HOW AN INJECTOR WORKS
INJECTOR SELECTION
INJECTOR SELECTION
ZERO SUCTION POINT
The numbers in
BLUE indicate the
back pressure point
at which no suction
occurs
WHY FLUID SUCTION VARIES WITH
PRESSURE DIFFERENTIAL
Suction is greater when the pressure differential is high because a larger
space in the injector experiences a vacuum

OTHER FACTORS AFFECTING
LIQUID INJECTION
• Specific Gravity different from water
• Pressure on suction port
• Material must be lifted
• Elevation different than sea level
See Technical Bulletin 1 for correction calculations

PROPER INSTALLATION RULE
The injector’s outlet cone must remain flooded – a measurable
amount of backpressure must be present for the injector to work
properly.
Examples of nobackpressure
installations (DO NOT
DO THIS):
• The injector has no
piping attached to the
outlet
• The injector is installed
vertically with the water
flow going down
