METER ORIENTATION
Magnetoflow Mag Meters can operate accurately in any pipe
line orientation.
However, the most recommended installation position is vertical
piping, with the the liquid flowing upward.
This installation practice ensures two objectives:
· The pipe remains completely full of liquid, even at low flow, low
pressure applications with a discharge to the atmosphere.
· Solid build-ups or sediments that could be part of the pro-
cess fluid will not deposit or accumulate on the liner and/or
electrodes.
The model 7500P mag is designed to measure flow in one direc-
tion only. Carefully observe the "forward flow" label attached
to the meter body and install the meter accordingly.
If horizontal piping orientation is required, the detector should
be mounted in a position at which the electrodes axis will
remain in an horizontal plane (3 and 9 o’clock position; see
figure below).
PIPING CONFIGURATION
Appropriate piping arrangements should be provided to ensure
the meter is not exposed to extreme pipe vibrations. The piping
arrangements should include appropriate pipe supports.
For optimum accuracy performance, it is required to provide
sufficient inlet and outlet straight pipe runs. An equivalent of
3 diameters of straight pipe is required on the inlet side of the
meter, and 2 diameters on the outlet side, measured from the
center of the meter body.
Avoid installing the detector close to flow disturbance generat-
ing valves and fittings.
Do not install the detector in the outlet side of Piston or Dia-
phragm type pumps. Avoid all pipe locations where the flow
is pulsating. Avoid installing the detector in the suction side
of any pumps; possible creation of vacuum can affect meter
performance or cause damage to the PTFE liner.
TEMPERATURE
Note: Environmental temperature of installation is not to exceed
maximum specification of 122°F (50°) for the meter.

UNPACKING AND INSPECTION
To avoid damage in transit, Badger meters are shipped to
the customer in a special shipping container. Upon receipt
of the meter, perform the following unpacking and inspection
procedures. If damage to the shipping container is evident, be
present when the meter is unpacked.
A. Carefully open the shipping container following any instruc-
tions that may be marked on the container. Remove all cush-
ioning material surrounding the meter and carefully lift meter
from container. Retain the container and all packing material
for possible use in reshipment or storage.
B. Visually inspect the meter for any physical damage such as
scratches, loose or broken parts, or any other sign of damage
that may have occurred during shipment.
NOTE: If damage is found, request an inspection by the car-
rier's agent within 48 hours of delivery. Then file a claim with
the carrier. A claim for equipment damaged in transit is the
responsibility of the customer.
STORAGE
If the meter is not to be installed right away, store it in it's original
container in a dry, sheltered location. Storage temperature: -4
to 158°F (-20 to +70°C)
