4. Process piping should not place unude strain on
the meter.
5. Provisions should be made to insure that thermal
explansion does not raise line pressure above the
maximum pressure rating of the meter.
6. All process piping should be clean and free of
debris to insure foreign material does not enter
the meter.
7. A
fl ow limiting valve should be installed down-
stream of the meter to maintain adequate back
pressure and to protect the meter from excessive
fl ow rates.
8. If require, an air eliminator should be installed
upstream of the meter.
9. Do not allow water to remain in the meter. If water
has entered the meter remove the inner unit and
clean it with a light lubricating oil.
10. Standard fl ow through the meter is from left to
right. If right to left fl ow is required, consult your
local Brodie agent or an authorized repair center.
11. The bolt pattern on the meter accessories allows
the meter accessory stack to be rotated in 90 de-
gree increments. The required position should be
selected prior to installing electrical service to the
meter. Care should be taken not to damage the
capillary tube on the temperature compensator if
so equipped.
12. Isolation valves should be installed on both ends
of the meter run to minimize product loss when
removing any of the components from the line.
Operation
CAUTION
Do not operate this meter in excess of the values
stated in 8 Specifi cations.
Brodie Meter Co., LLC has highly qualifi ed service
technicians who are available to provide start up
assistance. Contact Brodie or your local Brodie Autho-
rized Repair Center if service assistance is required.
Starting Flow Through the Meter
The following recommendations should be considered
when the meter is fi rst put into operation or any time
that the meter has been drained.
1.
If large volumes of debris are expected in thepro-
cess piping during start up it is recommended that
the measuring element be removed from the meter
until the lines are free of pipe scale, weld beads and
other types of foreign material. A spool piece may
be used as a temporary replacement for the meter.
The strainer basket should be removed to elimi-
nate the possibility of rupturing
.
2.
Slowly introduce product into the meter. Open the
upstream valve while the downstream valve re-
mains closed.
3.
Slowly bleed air from the system through the high
point vent.
4.
Once all air has been eliminated, slowly openthe
downstream valve. Allow the meter to run at ap-
proximately 20 percent of the maximum rated fl ow
for two minutes
.
Observe the rotation of the count-
er wheels to insure the meter is operating smooth-
ly. Continue opening the downstream valve until it
is fully open.
Care should be taken to insure the
maximum fl ow rate of the meter is not exceeded.
Confi rm that the setting on the fl ow control valve is
properly fi xed and is in control of the system.
5.
Do not close valves quickly. This can cause a pres-
sure spike which can damage the meter.
6.
Do not make adjustments to the meter or its ac-
cessories while the meter is turning. When adjuster
settings are changed, a small batch should be run
through the meter prior to making the next proving
run. This allows the adjuster components to shift to
the new setting.
7.
Prove the meter in order to establish a meter factor
under actual operating conditions. Proving records
and other pertinent meter data should be retained
in order to establish a performance history for the
meter.
