(2) Function to store the current parameters into the flash memory, so that these
parameters will be solidified and will be loaded as the default parameters every
time when power is turned on.
M27
Entry to store to or restore from the internal Flash memory, as many as 9 different
pipe parameter configurations
To save or load the current setup parameter, use the going up or going down keys
to change the address number, press ‘ENT’ key, and use going down or going up
keys to select to save to or load from the memory.
M28
Entry to determine whether or not to hold (or to keep) the last good value when
poor signal condition occurs. YES is the default setup.
M29
Entry to setup empty signal threshold. When the signal is less than this threshold,
the pipe is regarded as empty pipe, and the flow meter will not totalize flow.
This is based on the fact that, for most occasions, when pipe is empty, the
transducer would still receive signal, just smaller than normal, As a result, The flow
meter would show normal operation, which is not correct.
Make sure that the entered value must be less than the normal signal strength.
When much noisy signals are received, to make sure the flow meter will not
incorrectly totalize flow, there is also a ‘Q’ threshold should be entered in M.5
M30
Window for selecting unit system. The conversion English to Metric or vice versa
will not affect the unit for totalizers.
M31

2. USA gallon (gal)
3. Imperial Gallon (igl)
4. Million USA gallon (mgl)
5. Cubic feet (cf)
6. USA liquid barrel (bal)

The flow unit in terms of time can be per day, per hour, per minute or per second.
So there are 32 different flow rate units in total for selection.
