WORKING PRINCIPLE
57GUNMOD
The measurement system is based on the bore of the oil meter which contains two elliptical gears. The gear will
rotate when the oil flows through the bore of gun. The flow of oil is the same at each rotation. When gears
rotate, the generated pulse signal will be recorded to processes by a microprocessor. The magnetic coupling
function between gear with magnet and magnetic switch out of the bore of gun not only guarantees the bore
of gun leak-proof quality, but also ensures the pulse which produced by gear rotation will transmit to the
microprocessor on circuit board. The microprocessor has been converted the pulse into the volume of fuel by
adjusting parameters properly and displayed on the screen.
The measurement grease gun is adjusted with 10W-40 oil before leaving the factory. Each one has primary
parameter. It can be adjusted on spot and would maintain the best function that can be used to measure the
volume of oil if needs.
Please adjust on spot if operators want to measure precisely as the oil viscosity of factory may be different.
For different customers, due to the use of oil specifications are not the same, usually before use, for the oil flow
corrections in order to achieve the actual amount of oil and the meter display value of the same or close to
(reduce error).
Usually, when the oil meter was equipped with battery (automatically reads the parameters), it will show some
data on the screen, if the shown data is Error (Err), Please reset the data according to the below instructions.
Operation Methods:
1. First enter into the operation status, then press button “Total”.
2. Still into the operation status, press the button “Reset” for 2 seconds, then the flow meter will get into the
Setting Status.
3. Press the “Reset” button for another 2 seconds, now the flow meter will show new data on the screen.
4. The current display is clear and the cumulative is clear, for example: the initial image is above 0.75 and 2.5
as cumulative data. As the pictures below:
Picture A: 0.75 means current filling volume, while the number 2.5 means till now the total filling volume is 2.5L.
Picture B: means the current filling data is 0.00
