GMD is a measuring device for measurement of CO
2
content in beer, soft drin s and mineral water
in tan s and KEG cas s.

AKING OF SAMPLES
The device is ready for measurement at the moment of delivery.
Preceding the own measurement connect the device by fixing of inlet hose (3) to the sampling
point. The measured sample must flow through stainless tube (4) to the bottom of the vessel. The
inlet hose (3) must be secured at the sampling point not to fall out during ta ing of sample under
pressure.

2.2
D
ISCHARGING OF THE SAMPLE
Close the sampling valve on the tan , then open both inlet and outlet valves to remove any pressure
inside the hoses and the GMD. Then disconnect the inlet hose (3), place the outlet hose (5) to the
drain and turn the device upside down. At the same time hold the inlet hose (3) 10 cm over the
device. Chec visually if the transparent vessel (6) is empty.
If you are going to measure other samples, you don’t need to empty the GMD. You can rinse the old
sample with the new one by leaving the new beer flowing through the GMD about 30 s.
If you have finished measurement, clean the device. Rinse the device with clean water.

C
LEANING OF THE DEVICE
Open the inlet valve (1) and the outlet valve (2). Place the outlet hose (5) to the drain. Connect the
inlet hose (3) to the potable water supply. Afterwards open slowly the water coc and rinse the
device with water. Both ball valves (1,2) have to be open during rinsing.
Warning! Pressure of water must not exceed value 250 Pa.
Whole internal space of the vessel (6) must be filled with water during cleaning. During rinsing pull
out and consequently press down several times the button (9) to rinse both pump and capillary.
It is important to remove any traces of beer to prevent the piston getting stuc .
After rinsing:
Once the cleaning is over, switch off the water coc . Disconnect the inlet hose (3) from the water
coc . If you plan to use the device next day, do not discharge the water from the device and pull up
the button (9) to suc the water inside the pump.
If you want to discharge the water then place the outlet hose (5) to the drain and turn the device
upside down. At the same time hold the inlet hose (3) 10 cm over the device. First open the outlet
valve (2) and subsequently open the inlet valve (1) and discharge the water. Chec visually if the
graduated vessel (6) is empty.
Clean the external surface with soft flannel moistened with water. After this handling the device is
ready for next measurement.
The unit must not squirt water!

AFETY RECOMMENDATIONS
Measuring device of CO
2
content - types GMD (GMDK) may be operated only by person who
became completely acquainted with its function within the framewor of the training, or who
became thoroughly acquainted with the user’s guide of this device.
8
Measuring device GMD (GMDK) can be used only for determination of CO
2
content in the range of
measured values determined by technical conditions. Never connect the measuring device to the
withdrawal spots where measured parameters are over measuring capacity of the device.
Chec device before each measurement. Do not use visibly damaged device and contact the
qualified service personnel who provides service for delivered device.
Warning! It is forbidden to use the device for pressure higher than 600 Pa and for temperature
higher than +30 degrees Celsius. It could cause device destruction and staff injury.

AKING OF SAMPLES
Measuring device for measurement of CO2 content in beer, soft drin s and mineral water in
cylindro-conical fermenters, tan s and KEG cas s completed with withdrawal head for egs
(Optional accessories).
Chec device before each measurement. Do not use visibly damaged device.
Notice! Sludge the sampling point before connecting the device. Sludge the sedimented yeast to
fill inside the chamber only beer without sedimented yeast!
9
Chec button (9) on the top of the device if it is in secured position (10b). Afterwards connect the
device by fixing of inlet hose (3) to the sampling point. The inlet hose (3) must be secured not to
fall out with the pressure.
If there is a big difference in diameters of the hose and sampling valve, use a reduction in the
supplied hose and the other one in another hose satisfactory for safe sampling. We recommend to
fix the hoses on the reduction with clamps.
Place the outlet hose (5) to the drain, the inlet valve (1) is shut during this handling. Afterwards
open fully the valve of the sampling point and let beer or saturated beverage go into the inlet hose
(3) to inlet valve (1). Open fully the inlet valve (1) on the device.

ONTENT MEASUREMENT
Open both valves (1), (2) to let the sample fill in the transparent chamber (6) SLOWLY, to avoid
foam creation.
Let the beer flow through the device for at least 20s, 30s or more if you are rinsing the sample from
a previous measurement or if it’s the first measurement and the GMD was stored in a warmer place
before.
Fill the transparent chamber (6) completely with the sample. Chec visually if there is no foam or
bubbles inside the chamber (6)!
The device is on the ground during ta ing of sample.
Now first shut the outlet (2) valve, then the inlet (1) valve. Press the power button (12) to turn on.
Switch on the microcontroller by pressing the On ey and when the device is ready, press the Enter
ey. The GMD starts measuring continuously the pressure and waits for depressurization. You have
to open the outlet valve (2) to remove the overpressure from the tan . Open it slowly and close it
immediately after hearing the sound emitted by the buzzer and the display shows "close v.", which
indicates that the pressure is under threshold level. Then push out the button (9) of the secured
position (10b) and pull it out into the upper position (11) (loo pic.2). Hold it for a while in this
position to equalize the pressure. Then press down the button (9) to the very down unsecured
position (10 a). After this handling dissolved CO
2
is fluttered and the pressure increases in the
chamber (6). Repeat this action one more time.
You should not pump more than three times to get good results and a good repeatability.
If the device was stored in a warm place before using it, the first measurement won’t be relevant
because of big temperature variation.
Then loc the button (9) in the down secured position (10 b).
Then follow the procedure described in
