GENERAL INFORMATION

Congratulations on receiving your new
meter. This manual should assist you in
operating and maintaining your mechani­cal fuel meter. Please take a few moments
to read these instructions before installing
and operating your fuel meter. If you need
assistance, contact the dealer from whom
you purchased your meter. If you need fur­ther assistance, please call our Customer
Service Department at 1-800-835-0113.

Safety Instructions

Please read, understand, and follow the
safety instructions given here. It is your re­sponsibility to ensure that all equipment
operators have access to adequate instruc­tions concerning safe operation and main­tenance.

1. This meter is designed for use only
with thin viscosity petroleum fuels
such as gasoline (up to 15% alcohol
blends such as E15), diesel fuel (up to
20% biodiesel blends such as B20),
biodiesel (B100) and kerosene.

2. Do not use this equipment for dispens­ing any fluids other than those for
which it was designed. To do so may
damage the meter and will void the
warranty.

3. Observe precautions against fire or
explosion when dispensing fuel. Do
not operate the meter in the presence
of any source of ignition including run­ning or hot engines, lighted cigarettes,
or gas or electric heaters.

4. Any components such as hose, nozzle,
or pump added to your meter must be
statically grounded and approved for
use with petroleum fuels.

5. Avoid prolonged skin contact with
petroleum fuels. Use protective goggles,
gloves, and aprons in case of acciden­tal splashing or spillage. Change
saturated clothing and wash skin contact
areas promptly with soap and water.

The FM-530 Series of Mechanical Fuel
Meters are designed for the field measure­ment of thin viscosity petroleum fuels
only and are intended for use with pump
systems in the 5 to 30 GPM or 19 to 114
LPM flow range (not intended for grav­ity flow systems). Using mechanical
gears, these meters translate flow data from
a nutating disc into calibrated units which
are indicated on the face of the meter. This
meter is factory calibrated for diesel fuel.
Field calibration feature is available for
other fluids, see Calibration section.

INSTALLATION

Before installing your meter, review the
safety instructions given above. Examine
your meter to make sure there are no vis­ible signs of shipment damage. Plan your
meter installation by reviewing the follow­ing procedures. Your system must be
mounted on a vented tank. If the tank is
unvented, your local dealer or distributor can
supply a pressure cap.

Prior to installation, determine the fitting
angle desired and whether horizontal or
vertical orientation is required.

Rotate Fittings

To rotate inlet and/or outlet fittings, remove
the two nuts and bolts which secure each
fitting. Rotate the fitting to the desired ori­entation. Make sure the O-ring is fully
seated. Tighten the nuts and bolts snugly.

Change Orientation

1. Remove the two Phillips head screws
which secure the cover to the cover­plate assembly.

2. Remove the eight pairs of nuts and
bolts which hold the coverplate assem­bly to the housing. (Figure 1) Note the
position of the reset button.

Figure 1

3. Rotate the coverplate assembly and
counter to the desired orientation.
Make sure the flow arrow in the
housing points toward the outlet port.

orientation.

3. Install the meter on the pump using an
appropriately sized nipple. The meter’s
flow path is marked on the housing
exterior with an arrow pointing toward
the outlet port.

4. Install other system components on the
meter and tighten snugly.

OPERATION

Before use, review the safety instructions
given above. Visually check the meter to
ensure it is securely connected to other sys­tem components and there is no leakage.
Promptly wipe spilled fuel from the meter’s
exterior and other system components.

The large meter display represents the
Batch Total for each fuel delivery. Before
dispensing, reset the Batch Total to zero
by pushing the reset button. (Figure 3)

4. Make sure the housing O-ring is fully
seated and firmly tighten the eight nuts
and bolts which secure the coverplate
assembly.

5. Place the reset button in position. Secure
the cover to the coverplate assembly
with the two Phillips head screws.

Meter Installation

1. Remove protective plugs from the
meter inlet and outlet ports.

2. Wrap threaded male connections with
Teflon® tape or use a pipe sealant com­pound compatible with petroleum
fuels. We recommend Lock-Tite thread

The small display represents the Cumula­tive Total of all fuel deliveries and cannot
be reset.

CALIBRATION

The meter is accurately calibrated at the
factory for use with diesel fuel. Due to dif­ferences in viscosity and flowrates, the
meter may require recalibration to measure
other fuels or to adjust for inaccuracies.

1. Purge air from the meter and fuel sys­tem by dispensing fuel into a container
until a full flow occurs. Close the
nozzle.
