Powering On
When power on, the self-diagnosis program will start to run. If any error is detected, an error
code will be displayed on the screen (see Error Codes and Solutions). After that, the system
will run automatically using the programmed parameters.
If it is the first time to use or install on a new site, new installation site parameters are needed
to enter. Any parameters which are set by the user will be saved permanently until next change.
When the user reedits the parameters or removes the transducers, the flow meter will
recalculate automatically, and operate normally with the newly set parameters.
Keypad Operation
Follow these guidelines when using the Flowmeter keypad:
for setting and display mode, when in setting mode, press it to turn to previous menu,
and for scrolling up and down to select the menu, when press to move to
next digit, press and the numbers scroll from 0 to 9. Select them. Press to
confirm, press to delete.
For displaying flow rate and totalize; For displaying flow rate curve;
For displaying signal diagnosis information; For SD card data collection
operation.

Main screen
When power on, the self-diagnosis program will automatically start to run.
First comes the welcome screen:
Signal Quality (SQ value), Net Totalizer (NET), Positive Totalizer (POS), Negative Totalizer
(NEG), Flow Velocity (Vel.).
Note: SQ value is short for Signal Quality. It indicates the level of the signal detected. SQ
value is indicated by numbers from 0~99. 00 represents the minimum signal detected
while 99 represent the maximum.

Display the velocity and flow curve. The data will be updated only stay in this screen.
Display the signal strength, Date and time, Signal quality, Speed ratio (TOM/TOS), Sound
Velocity, Total transit time (TOF), Delta time (DT).
About TOM/TOS: Display the ratio of actual measured transmission time to calculated
transmission time according to customer requirements. Normally the ratio should be 100±3%.
If the difference is too large, the user should check that if the parameters are entered correctly,
especially the sound velocity of the fluid and the installation of the transducers.
Display the signal strength, flow rate, flow totalizer and collection time. Press ENT to choose
stop or continue, Double-click ENT to stop data collection, Flow data will be stored on the SD
card. Cannot any operation when the meter run collection, once it exits, the collection is stop.

reliable perpetual calendar chip.
The format for time setting is 24-hour.
5. System lock:
System lock is readable but uneditable to prevent operation error due to unauthorized
tampering.
6. Damping:
The damping function will stabilize the flow displaying. Essentially, it is a part of the
signal filter. Enter the coefficient and increase it to improve stability. However, due to
over-damping, the displayed measurement may be slightly delayed. The measurement
time is too long, especially when the flow fluctuates greatly, and there is no response to
real-time fluctuations. Therefore, the damping should be kept to a minimum and increased
just enough to reduce the fluctuation to an acceptable level for 3 to 10 seconds.
The damping coefficient is between 0~999 seconds. 00 means no damping; 999 means
maximum damping. In applications, a damping factor of 3~10 is usually recommended.
7. Back light:
Brightness is adjustable between 5% to 100%

Setup Menu – Calibration
0. Scale factor:
Scale factor refers to the ratio between “actual value” and “reading value”. For example,
when the measurement is 2.00, and it is indicated at 1.98 on the instrument, the scale
factor reading is 2/1.98. This means that the best scale factor constant is 1.
During operation, there still exists possible difference in pipe parameters, etc. The “scale
factor” may be necessary when use on different pipes. Thus, scale factor calibration is
specially designed for calibrating the differences that result from applications on different
pipes. The scale factor entered must be one that results from actual calibration.
1. 4-20mA Calibration:
Check if the current loop has been calibrated before leaving factory.
Select 4mA, and at the same time check with an ammeter to verify that output terminals
agree with the displayed values. It is necessary to re-calibrate the current loop if it display
over the permitted tolerance.
20mA calibration is with the same method.
Note: When verifiering the current loop, make sure the flow meter has run for more
than 20 minutes.
2. Set zero:
When the fluid is in the static state, the displayed value is called “Zero Point”. When
“Zero Point’ is not at zero in the flow meter, the difference is going to be added into the
actual flow values and measurement differences will occur in the flow meter.
Set zero must be carried out after the transducers are installed and the flow inside the pipe
is in the absolute static state (no liquid movement in the pipe). Thus, the “Zero Point”
resulting from different pipe mounting locations and parameters can be eliminated. The
measuring accuracy at low flow is enhanced by doing this and flow offset is eliminated.
3. Low flow cut:
If the flow rate falls below the low flow cutoff value, the flow indication is driven to zero.
This function can prevent the flow meter from reading flow after a pump as shut down but
there is still liquid movement in the pipe, which will result in tantalization error.

LRF-6000H Ultrasonic flowmeter
Page 14 of 29
Generally, 0.03m/s is recommended to enter as the low flow cutoff point. The low flow
cutoff value has no relation to the measurement results once the velocity increases over
the low flow cutoff value.
4. Manual zero point:
This method is not commonly used. It is only suitable for experienced operators to set
zero point under conditions when it is not preferable to use other methods. Enter the value
manually to add to the measured value to obtain the actual value.
For example:
Actual measured value ＝250 m3/h
Value Deviation ＝-10 m3/h
Flow meter Display ＝240 m3/h
Normally, set the value as “0”.
5. AI1 Calibration: (For wall mount models)
Calibration analog input channel 1.
6. AI2 Calibration: (For wall mount models)
Calibration analog input channel 2.
7. Automatic Correction:
With the function of automatic flow correction, the flow lost in an offline session can be
estimated and automatically adjusted. The estimated value is based on the average value
multiplied by the time period during which the meter is offline. The average value is
derived from the flow before the offline and the flow measured after the offline. Select
"No" to cancel this function.
8. Linear correction:
Sometimes there is a small deviation between the flow model and the actual measured
value. In order to make the measured value more closed to reality, the flow data can be
corrected according to the calibration value.
Up to 16 segments can be corrected according to the flow rate.

Measurement Site Selection
When selecting a measurement site, it is important to select an area where the fluid flow profile
is fully developed to guarantee a highly accurate measurement. Please follow these guidelines
for selecting a proper measurement installation site:
Choose a section of pipe, which is always full of liquid, such as a vertical pipe with flow in the
upward direction or a full horizontal pipe.
Make sure that the pipe surface temperature at the measuring point is within the transducer
temperature limits.
Consider the inside condition of the pipe carefully. If possible, select a section of pipe where its
inside is free excessive corrosion or scaling.
Examples acceptable measurement site selection are shown in the figure below.
