If the user-type-transducer is selected, you need enter additional 4 user-type-wedge
parameters that describe the user transducers.
If the PI-type transducer is selected, you need enter additional 4 PI-type transducer
parameters that describe the PI-type transducers
M24
Window for selecting the transducer mounting methods
Four methods can be selected:
(0) V-method (1) Z-method (2) N-method (3) W-method
M25
Display the transducer mounting spacing or distance
M26
(1)
A switch for the parameters in flash memory will be loaded when power is turned on.
The default option is that the parameters will be loaded. If this switch is not turned on,
the system will try to use the parameters in the system RAM, if these parameters are
ok, otherwise the system will load the parameters in flash memory
(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
Window for selecting flow rate unit system.
