问:
We have installed UZI-0.8 on a tank of 60cm height and set
60cm measurement height. Is it ok or we would better set
80cm height?
Answer: It
is recommended to set the measuring height with a spare.
For example, the valve of the tank is broken, the weather
is hot, so the tank has swelled and became 65cm instead of
60cm. Thus we get 5cm of unrecorded volume.
问:
We have found a perfect place for installation. The signal
was good. But when we glued the radiator and conduct the
cable into the driver’s cab the signal was lost. We have
only 1,9V on the blue wire. Is it a break of the cable?
Answer:
Please check the connectors: radiator-extension cable and
extension cable-processing box. Check if the processing
box connected to the right end of the extension cable.
Here should be the end with 3 rubber rings on the
connector. If you have used another end of the cable the
connector might has a backlash and the contact is lost.
问:
We have installed the radiator strictly according to the
manual: cleaned the surface with an abrasive, defatted it
and put some water on the radiator working surface. In the
test mode the analog output (the green wire) had 9,6V, but
in the measuring mode it shows only 1,3V. The same is in
several places. Is this correct?
Answer: For
the beginning you should know the height of your tank and
the height of the fuel inside. If your tank height is 40cm
and this was set correctly by the micro switches and the
fuel level is 6 cm then you get correct data.
It is easy to calculate: for example, the height of the
tank is 80cm, max voltage in the Test mode is 8V, the fuel
level is 60cm. So the voltage in the measuring mode should
be calculated (8: 80)х 60= 6. So if the voltage on the
analog output is close to 6V the place for the
installation has been chosen correctly and you get the
real level.
问:
We have installed the radiator in a winter time. Firstly
we put some water on the radiator, then the water has
frozen and we used a lubricant. But we have not got any
signal. On the other hand when we put the radiator in
diesel the green LED on the processing box stared
blinking. Is the radiator defective?
Answer: No,
the radiator is in order. The problem is subzero
temperature. You should use non-frozen liquids to provide
the acoustic contact: for example, engine oil, diesel or
the liquid which is used for cleaning the windshield in
winter time.
问:
Yesterday we tried to install the radiator on the VOLVO
B80M. The tank is made of plastic, probably glass fiber.
We check a lot of places on the tank bottom but no signal
at all. However on a bucket, barrel and plastic bottle it
works. What could be the reason of the problem?
Answer: If
the tank has an uneven surface inside it is typical for
glass fiber. The ultrasonic signal beam is dispersing in
such materials. It works like a diffuser. Unfortunately
for this kind of tanks other fuel-levels should be used.
On the other hand UZI perfectly works with stamped plastic
tanks.
问:
In FlashReaderUser.exe program the bookmark
"Configuration" is not available. What could be a reason?
I've updated the drivers and EIA-485 port was connected
without any problem.
Answer: The
problem could be in the chosen COM port and baud rate. You
should check if the COM port is not occupied by another
program. If there is no free port you should choose it
manually. Check which baud rate is chosen? Choose 19200.
问:
I’ve run “Oscilloscope” program and pressed the radiator
to a bottom of a bottle with mineral water. There are no
any reaction of the oscilloscope. Does UZI work with
water?
Answer: UZI
works with water as well as with other liquids. Please do
the following:
1. Turn the device in the Test mode by sliding the micro
switch 1 of the processing box in the position 1.
2. Set the measuring height = 30cm (the micro switch 2,
3 and 4 in position 1).
3. Connect the UZI-programmer (reader) to the port 2 of
the processing box and to USB socket out your PC.
4. Connect the connector of the extension cable with 3
rubber rings to the processing box, another connector with
1 rubber ring connect to the radiator cable.
5. Supply power (red cable (+), black cable (-).
6. Put some water or gel or oil over the working surface
of the radiator and press to the bottle
bottom. The bottle bottom should be flat and in horizontal
position.
7. Run “Oscilloscope” program.
8. Open the port and press the red button in the left
top corner of the program window.
9. Now the picture should be displayed.
问:
We want to measure liquidized gas. Do we need a special
version of UZI? Is it different from gasoline version of
UZI?
Answer: UZI
system is universal. The only thing that should be done is
to make settings via a special program and UZI-programmer
(reader). You can buy the UZI-programmer (reader) from us;
all the programs will be supplied for free. In the manual
of UZI-programmer (reader) you could find full information
about the setting of the fuel type as well as about other
settings.
