Chapter 3 How to use
3.1How to determine whether the flowmeter is working properly
Under normal circumstances, in the lower right corner of the LCD display with "R"
appears, that the flowmeter is working properly. If "H" appears, it means that the
received signal is poor, please refer to the self-diagnosis chapter.
If "I" appears, it means that no signal is received.
If "J" appears, it means the flowmeter may have a hardware failure, please refer to
the self-diagnosis chapter.
3.2 How to determine the direction of liquid flow in the pipeline
Make sure the current flowmeter is working properly.
Check the instantaneous flow, if the display is a positive value, the direction of
liquid flow from the red sensor to the blue sensor: if the display is a negative value,
the direction of liquid flow from the blue sensor to the red sensor.
3.3 How to change the measurement unit system
Select the imperial or metric system in the M30 menu window.
3.4 How to select the flow unit
Select in the menu window M31.
After selecting the flow rate unit, select the time unit.
3.5 How to select the accumulator multiplier
Use window M33 to select an appropriate accumulator multiplier, not too fast or too
slow, depending on the flow rate, and preferably keep it to a few pulses per minute.
If the multiplication factor is too small, lost pulses will occur, as the minimum pulse
period is designed to be 500 milliseconds.
If the multiplication factor is too large, the accumulated pulses will be too slow,
which will affect the work of other secondary instruments.
3.6 How to open and close the accumulator
Use M34,M35 and M36 to turn the positive, negative and net accumulators on and
off respectively.
