GENERAL INFORMATION
The purpose of this manual is to assist
you in installing, operating and main-
taining your mechanical fuel meter�
Please take a few moments to read
these instructions before installing and
operating your fuel meter�
The MR 5-30 Mechanical Fuel Meter is
designed for the field measurement of
thin viscosity petroleum fuels only and
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 kero-
sene grade (JET A). Field calibration
feature is available for other fluids, see
Calibration section�
For ground-based refueling only.
Do not use in or on the aircraft.
Use this meter with aviation gasoline
(AVGAS 100LL) and kerosene grade
(JET A).
Do not use this equipment for dis-
pensing any fluids other than those
for which it was designed. To do so
may damage the meter and will void
the warranty.
