• The 3120-114 meter is an oval gear model
pulse transmitter. It is intended for installation
in the distribution line and connection to a
monitoring equipment.
• It is recommended that the flow rate measured
is placed approximately in the middle of the
operating range of the meter. Operation with
flow near the ends of the operating range may
cause a decrease in measurement accuracy.
• The equipment includes a LED indicator of valve
opening status (see section "Installation" for
proper configuration).
This equipment is designed to be installed directly
in distribution line pipe. The meter has a 1/2" NPT
connection at the inlet and outlet. It also includes
an inlet flange and a flange at the outlet with
seating for an O-ring seal. Avoid installing the unit
between rigid connections to prevent efforts
transmission of the pipeline.
It is recommended to install a pressure relief sys-
tem on the line to prevent damage from thermal
expansion.
To prevent damage from dirt or solid particles
carried by the fluid is recommended the installa-
tion of a 200-mesh strainer at the meter inlet.

commercial transactions.
• Do not alter or modify the unit.
• Do not exceed the maximum unit working
pressure. See page 4, technical specifications.
• Use the unit with fluids and solutions which
are compatible with the moist parts of the
unit. See the relevant section of the technical
specifications.
• Observe the manufacturer's safety warnings for
the fluids used.
• The meter has been manufactured with low
tolerances in order to ensure high precision over
a wide range of flows and viscosity.
Installation
For connection to the monitoring equipment keep
in mind that the meter generates 310 ppq (pulses
per quart) for proper configuration.
Depending on the monitoring equipment units
system, shall be established the following settings:

Configuration 328 ppl
Using fluids with high or low viscosity, as well as if
working with high flows or very low flows, calibration
may be required adjusting pulses per unit.
