Notice!
Thank you for choosing model LRF-6000H Portable Ultrasonic Flowmeter.
This instruction manual contains the important using and operation information of the flow
meter. Please read carefully the reference manual before operations to make your portable
ultrasonic flowmeter exert the best performance.
If the operation is wrong, it will affect the normal operation of the flow meter, reduce the
service life of it or cause some malfunctions.
This manual will present how to use the flow meter step by step. Beginning with the product
component, installation, wiring, quick setting and so on which will let you very easily operate
the flow meter.
By knowing more menu settings, the powerful function options and output functions of the
flow meter can meet your higher requirements.
Note: Some content in this manual may be different from the flow meter you purchased,
depending on the optional configuration requirements at the time of purchase. On the
other hand, due to the design changes and upgrade needs of the product, there is no
indication in the manual. Please pay attention to the version number and the added
Attached page description.

Transmitter Installation
Take out the transmitter. Shown from left to right on the top of model 6000H are the upstream
transducer connector, downstream transducer connector, and 4~20mA output connector.
On the left side of the transmitter, are the power recharging and the power switch.
One rechargeable 11.1V Lithium battery and matching battery charger are coming with.
Please refer to the below diagram for specific connection information:
CAUTION
Caution
Wire when it is power-off. The flow meter must be grounded reliably before
installation and use.

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.
