TUF-2000F User Manual
Displays the Time Ratio between the Measured Total Transit Time and the
Calculated time. If the pipe parameters are entered correctly and the transducers
M91
are properly installed, the ratio value should be in the range of 100±3%. Otherwise
the entered parameters and the transducer installation should be checked.
Displays the estimated fluid sound velocity. If this value has an obvious difference
M92
with the actual fluid sound speed, pipe parameters entered and the transducer
installation should be checked again.
M93
Displays total transit time and delta time(transit time difference)
Displays the Reynolds number and the pipe factor used by the flow rate
M94
measurement program. Pipe factor is calculated based on the ratio of the
line-average velocity and the cross-section average velocity.
(1) Display the positive and negative energy totalizers
(2) Upon entering this window, the circular display function will be started
automatically. The following windows will be displayed one by one, each window
will stay for 8 seconds: M95>>M00>>M01>>M02>>M02>>
M95
M03>>M04>>M05>>M06>>M07>>M08>>M90>>M91>>M92>> M93>>
M94>>M95. This function allows the user to visit all the important information
without any manual action.
To stop this function, simply press a key. Or switch to a window other than M95.
This is not a window but a command for the thermal printer to advance 5 lines of
M96
paper.
This is not a window but a command to print the pipe parameters.
M97
By default, the produced data will be directed to the internal serial bus (thermal
printer). You can also direct those data to the serial communication port.
This is not a window but a command to print the diagnostic information.
M98
By default, the produced data will be directed to the internal serial bus (thermal
printer). You can also direct those data to the serial communication port.
This is not a window but a command to copy the current display window. By
default, the produced data will be directed to the internal serial bus (thermal
printer). You can also direct those data to the serial communication port.
M99
By use of the window copying function, you can hardcopy very window displaying
manually by switching windows, or you can obtain the window displaying data by
communication.
Browse the 32 recorded instrument power-on and power-off date and time with the
M+0
flow rate at the time of power on and off
Displays the total working time of the flow meter.
M+1
When the backup battery is removed, the total working time will be reset to zero.
M+2
Displays the last power-off date and time
M+3
Displays the last power-off flow rate
M+4
Displays how many times of has been powered on and powered off.
A scientific calculator for the convenience of field working.
All the values are in single accuracy.
M+5
The calculator can be used while the flow meter is conducting flow measurement.
Water density and PT100 temperature can also be found in this function.
Set fluid sound speed threshold
Whenever the estimated sound speed (displayed in M92) exceeds this threshold,
M+6
an alarms signal will be generated and can transmitted to BUZZER or OCT or
RELAY.
