ELECTRONIC LUBE METER

MODEL 967

Series B

BEFORE METER CAN BE PLACED IN SERVICE AFTER

REPAIR, METER MUST BE TESTED AND APPROVED IN

ACCORDANCE WITH U.S. GOVERNMENTS WEIGHTS

AND MEASURES STANDARDS

NEW METERING SYSTEMS MUST BE PURGED PRIOR

TO INSTALLATION OF METERING CONTROL VALVE TO

FREE SYSTEM OF CONTAMINATES.

DESCRIPTION

The electronic lube meter is designed specifically to

dispense motor oils (S.A.E. 5-50), gear oils (S.A.E. 80-240),

automatic transmission fluid, and antifreeze (Ethylene

Glycol) solution.

The electronic register module contains a microprocessor

board powered by a Lithium battery with an expected life of 3

to 5 years depending on use. It can be programmed to

dispense in pints, quarts, liters, or gallons and will totalize

in liters or gallons. A calibration factor and unit of measure

are programmed during factory test. Unlike mechanical

meters, these units can be electronically re-calibrated in the

field when necessary. A 5-digit liquid crystal display, accu-

rate to the second decimal place, shows the exact amount

of fluid dispensed. The entire register module is protected

from the wear and tear of normal shop use by a rugged,

glass filled, shock resistant, nylon housing.

OPERATION

As fluid passes through the metering chamber by entering

the inlet port, it displaces the piston and exits through the

outlet port. Each oscillation of the piston displaces a given

volume of fluid. Controlled clearances between the piston

and chamber wall insure minimum leakage. As the piston

oscillates, its center hub rotates a magnet which activates

the microprocessor.

Depressing the RESET button before each use resets the

totalizer to zero. Squeezing the trigger handle dispenses the

fluid.

The total amount of fluid dispensed from inventory can be

checked periodically by depressing the TOTAL button. If the

units dispensed are pints, quarts, or gallons, the totalizer

will read in gallons. If the units dispensed are liters, the

totalizer will read in liters.

The Lincoln Model 967 Series "B" Electronic Lube Meter is a sophisticated device designed for the precise dispensing of various automotive fluids. Its primary function is to accurately measure and control the flow of motor oils (SAE 5-50), gear oils (SAE 80-240), automatic transmission fluid, and antifreeze (Ethylene Glycol) solution.

Function Description

The core of the meter's operation lies in its electronic register module, which houses a microprocessor board powered by a Lithium battery. As fluid passes through the metering chamber, it displaces a piston. Each oscillation of this piston displaces a known volume of fluid. A magnet attached to the piston's center hub rotates, activating the microprocessor to count these oscillations. This data is then translated into a precise measurement of the dispensed fluid.

The meter features a large, 5-digit LCD display, 5/16" high, with two decimal point precision, showing the exact amount of fluid dispensed. Users can reset the totalizer to zero before each use by depressing the RESET button. Squeezing the trigger handle initiates fluid dispensing. The total amount of fluid dispensed from inventory can be checked periodically by depressing the TOTAL button. If the units dispensed are pints, quarts, or gallons, the totalizer will read in gallons. If the units dispensed are liters, the totalizer will read in liters.

Usage Features

The electronic lube meter offers several user-friendly features:

Large LCD Display: Provides clear and easy-to-read measurements.
Two Decimal Point Precision: Ensures highly accurate readings of dispensed fluid.
Push Button Calibration: Allows for electronic recalibration in the field, eliminating the need for mechanical adjustments.
Totalization in Gallons or Liters: Tracks the total amount of fluid dispensed from inventory.
Delivery in Pints, Quarts, Liters, or Gallons: The unit of measure can be programmed to suit specific needs.
Low Battery Indicator: Alerts the user when the battery needs replacement.
Rugged Construction: The entire register module is protected by a glass-filled, shock-resistant nylon housing, designed to withstand normal shop use.

Programming Instructions:

The meter's programming switch, located on the underside of the module, is used to activate programming procedures.

TOTAL Button: When depressed alone, it displays total GALLONS or LITERS used. In programming mode, it selects items to be changed.
RESET Button: Momentarily clears the display. In programming mode, it changes the flashing object on the display.

To Change Units of Measure:

Remove 3 screws holding the electronic register module to the lube meter body.
Depress the PROGRAMMING switch for 5 seconds and release to activate programming. A unit of measure symbol will flash.
Toggle the RESET button until the desired unit of measure symbol appears.
Depress the PROGRAMMING switch for 5 seconds and release to end programming. This locks the selected program and blanks the display.
- Note: Changing any unit of measure will reset the totalizer to zero.

To Recalibrate:

Display the existing meter correction factor by depressing and holding TOTAL and RESET buttons. Make a note of this number.
Calculate a new meter correction factor. For example, if the meter delivers 4.200 quarts but displays 4.000 quarts, the error factor is 4.2 / 4.0 = 1.05. If the existing correction factor is 0.995, the new factor would be 0.995 * 1.05 = 1.045.
Remove 3 screws holding the register module to the meter.
Depress the PROGRAMMING switch for 5 seconds and release to activate programming.
The display will show the existing meter correction factor and the programmed unit of measure symbol flashing.
Toggle the TOTAL button until the leftmost correction factor digit to be changed begins to flash.
Toggle the RESET button until the desired digit appears.
Repeat steps 6 and 7 for each digit of the correction factor.
Depress the PROGRAMMING switch for 5 seconds and release to end programming. This locks the selected program and blanks the display.
Reinstall the register to the lube meter.
- Note: After programming, the display will be blank. Depress RESET or TOTAL button to reactivate the display.
- Note: The original meter correction factor is written on top of the meter housing in black ink when factory calibrated. Use the correction factor shown on the display if it has been revised after field installation.

Maintenance Features

Fewer Moving Parts: Contributes to reduced maintenance costs compared to mechanical meters.
Replaceable Battery: The Lithium battery has an expected life of 3 to 5 years, depending on use, and is easily replaceable.
Battery Replacement Procedure:
1. Remove the dial from the meter.
2. Remove 4 screws from the back of the dial to access the battery.
3. Remove the old battery and replace it with a lithium 1/2AA Battery.
4. After battery replacement, the meter must be reprogrammed.
Troubleshooting Guide: The manual includes a flowchart for diagnosing common issues such as "Problems with Meter," "Leaking at Handle Trigger Assembly," "Leaks after shut-off," and "Faulty Nozzle." This guide directs users to check components like O-rings, flow rate, meter pressure, valve seat assembly, and gland packing.

Important Cautions:

Before the meter can be placed in service "AFTER REPAIR," it must be tested and approved in accordance with U.S. Government's Weights and Measures Standards.
New metering systems must be purged prior to installation of the metering control valve to free the system of contaminates.
