Select the Specific Heat Value.
Factory default is ‘GB’. Under this setting, the flow meter will calculate the enthalpy of
water based on the international standard.
If the fluid is other than water, you should select option ‘1. Fixed Specific Heat’, and enter
the specific heat value of the fluid.
Turn on or turn off the Energy totalizer.
Select thermal energy totalizer multiplying factor.
Factory default is ‘1’.
1.
Display the temperature difference
2.
Window for entering the lowest temperature difference.
Heat meter is on
1. Inlet
2. Outlet
Select the heat meter installation place.
Display signal strengths S (one for upstream and one for downstream), and signal quality
Q value.
Signal strength is presented by 00.0 to 99.9, the bigger the value, the bigger the signal
strength will be, and more reliable readings will be made.
Q value is presented by 00 to 99, the bigger the better. It should at least be great than 50
for normal operations.
Displays the Time Ratio between the Measured Total Transit Time and the Calculated
time. If the pipe parameters are entered correctly and the transducers 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 with the
actual fluid sound speed, pipe parameters entered and the transducer installation should be
checked again.
Displays total transit time and delta time(transit time difference)
Displays the Reynolds number and the pipe factor used by the flow rate measurement
program. Pipe factor is calculated based on the ratio of the line-average velocity and the
cross-section average velocity.

Display the positive and negative energy totalizers

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>>
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 paper.
This is not a window but a command to print the pipe parameters.
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.
