GENERAL INFORMATION
The purpose of this manual is to assist you in installing, operating, and
maintaining your mechanical fuel meter. Please take a few moments to read
these instructions before installing and operating your fuel meter.
SAFETY INSTRUCTIONS
The following safety alert symbols are used in this manual.
DANGER
DANGER indicates a hazardous situation which, if not avoided, will result in
death or serious injury.
WARNING
WARNING indicates a hazardous situation which, if not avoided, could result in
death or serious injury.
CAUTION
CAUTION indicates a hazardous situation which, if not avoided, may result in
minor or moderate injury. It is your responsibility to:
- Know and follow applicable national, state, and local safety codes pertaining to installing and operating equipment for use with flammable liquids.
- Know and follow all safety precautions when handling petroleum fuels
- Ensure that all equipment operators have access to adequate instructions concerning safe operation and maintenance.
-
Appropriate Use of QM Meter:
a. The UL Approved version of this meter is for use only with thin viscosity petroleum fuels such as gasoline, gasoline-ethanol blends (E15 maximum), diesel, and kerosene.
b. The non-UL Approved version of this meter is for use only with diesel fuel and kerosene. -
DANGER 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.
-
WARNING Any components such as hose, nozzle, or pump added to your meter must be statically grounded and approved for use with petroleum fuels.
-
WARNING 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.
This meter is designed for the field measurement of thin viscosity petroleum fuels only and intended for use with pump systems up to 40 GPM (150 LPM) flow range (not intended for gravity flow systems). Using mechanical gears, these meters translate flow data from positive displacement oval gears into calibrated units which are indicated on the face of the meter. This meter is factory calibrated for diesel fuel. The 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.
If the meter is located in a rigid piping system where the fluid is trapped (for example, by gravity, valves, or nozzles) thermal expansion of the fluid can create pressure spikes that can damage a meter. Install a thermal relief valve or otherwise allow for thermal expansion of the fluid.
The flowmeter MUST be mounted so that the rotor shafts are in a horizontal plane. Mounting the meter with the mechanical display facing horizontally will orient the rotor shafts correctly. The mechanical display should never face upwards or toward the ground. The weight of the rotors must be supported by the horizontal rotor shafts. If installed incorrectly, performance, life, or accuracy could be affected. (see Figure 1)
Liquid can flow in a horizontal direction, or a vertical direction, but in each case, the rotor shafts must be in a horizontal plane.
It is preferred to install the flow-meter upstream of flow control or shut-off valve, as the backpressure provided by the valve will be beneficial to system accuracy. The flow meter should remain full of liquid at all times when connected.
Do not operate the flow-meter directly discharging to the atmosphere. Prior to installation, determine whether the horizontal or vertical flow is required.
For vertical flow installations, the liquid should travel from bottom to top, i.e. it should rise vertically through the flow-meter. This will ensure that the flow-meter remains full of liquid, and will prevent air entrapment in the meter.
The back of the meter housing is embossed with “INLET” and “OUTLET” adjacent to its respective port to assist in correct piping connections.
Changing Display Orientation
- The mechanical display case can be removed, rotated, and reinstalled for easy reading with either horizontal or vertical flow. (see Figure 2)
- Using the 5mm hex L-wrench provided with the meter, remove the (4) M6 socket screws that attach the register case to the housing.
- Without separating the mechanical display from the housing, rotate to the desired orientation.
- Reinstall the (4) M6 socket screws and tighten them to 42-46 lb-in [4.7-5.2 N • m] torque.
Note: By first removing the (4) M4 socket screws and top cover, better interior viewing can be achieved. This is not a mandatory step though.
Meter Installation
-
Remove the protective plugs from the meter inlet and outlet ports. The inlet port has a 100 mesh stainless steel conical strainer installed.
CAUTION
The mesh strainer must always be installed when operating the meter; otherwise, particles may enter the metering chamber and disrupt the smooth operation of the oval gears. -
Wrap threaded male connections with thread tape or use a pipe sealant compound compatible with petroleum fuels.
-
Install the meter on the pump using an appropriately sized nipple. The bottom of the meter housing is embossed with “INLET” and “OUTLET” adjacent to its respective port to assist in correct piping connections.
-
Install other system components onto the meter and tighten.
OPERATION
ALWAYS FOLLOW SAFETY PRECAUTIONS WHEN OPERATING THIS EQUIPMENT. REVIEW THE
SAFETY INSTRUCTIONS. Before each use, 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 turning the knob. (see Figure 3)
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 flow rates, the meter may require recalibration to measure other fuels or to adjust for inaccuracies. A gear replacement kit is available (PN 139500-15, see Illustrated Parts List section) to convert the meter to unleaded fuels.
-
To adjust the calibration of the meter, gain access to the calibration screw by performing the following: (see Figure 4)
-
Remove the back plate and the (4) screws retaining it. The O-ring seal under the plate must not be damaged.
-
Using the 5MM hex L-wrench provided with the meter, adjust the calibration screw as required.
-
Note: The calibration screw setting may have been adjusted at the factory. The gasoline setting is approximately fully closed (turn clockwise). Do not overtighten the screw against the seat.
-
Reinstall the plate, (4) screws and the O-ring seal if removed. Tighten (4) screws to 42-46 lb-in [4.7-5.2 N •m] torque.
MAINTENANCE
The meter’s strainer should be cleaned at regular intervals, especially if
reduced
flow is encountered.
Clean or Replace Strainer
-
Remove the socket screws at the inlet fitting. Remove the fitting, Oring, and strainer. (see Figure 5)
-
The strainer rim is pressed into the housing inlet but can be removed by carefully grasping the end with pliers and pulling with a wiggling motion until free.
-
Using a fine brush, clean the strainer. Replace the strainer as necessary.
-
Wipe the housing inlet clean and reinstall the strainer, pressing it into the strainer bore. It is designed to be field pressed back into place using the end of a clean 1” pipe nipple or similar tube tool using light hammer taps.
CAUTION
The mesh strainer must always be installed when operating the meter; otherwise, particles may enter the metering chamber and disrupt the smooth operation of the oval gears. -
Wipe clean the fitting and O-ring groove. Coat the O-ring with oil or light grease and seat into the fitting groove.
-
Reinstall the inlet fitting and screws. Tighten screws to 42-46 lb-in [4.7-5.2 N• m] torque.
