AQUA-GLO SERIES V WATER DETECTOR KIT
OPERATING PROCEDURE MANUAL
INTRODUCTION
The Aqua-Glo Series V Water Detector Kit is used to measure the amount of undissolved water in kerosene-type jet fuels.
It can be used on other fuels by following special procedures in the section titled, "Other Fluids."
A measured sample of fuel is passed through a treated detector pad or "test pad." Undissolved (free) water in the fuel will
react with the test pad. When the pad is subsequently illuminated by ultraviolet light, the coating that was contacted by free
water will fluoresce (glow) a bright yellow with the brightness increasing for increasing amounts of free water in the fuel
sample. Water content is read out by the Aqua Glo instrument in parts per million by volume. By varying the fuel sample size,
the standard range of the instrument of 1 to 12 ppm can be increased to as much as 60 ppm of free water.
METHOD DESCRIPTION
The following procedure is primarily applicable for dynamic line sampling; that is, taking the fuel sample while the fuel
system is flowing and through the test pad without exposing the sample to the atmosphere or to a sample container. The use
of sample containers such as bottles or cans for the temporary storage or transport of the sample will result in large errors
due to changes in temperature, adsorption of water on container walls, etc., and is not recommended. The amount of free
water in a sample is very sensitive to temperature.
For a simplified step-by-step procedure, go to the end of this manual for the Abbreviated Procedure; first time users should
read the entire manual first.
CALIBRATION
An encapsulated pad labeled "Calibrating Standard" is provided in a separate container in each kit. Note the "set" number
on the back of this pad. Place the calibrating standard in the hinged flap window with the blank side (the side without the
set number) facing the instrument. Turn on the ultraviolet lamp and then press and hold the switch button on the photocell
comparator ("Instrument Pack"). This button is located within a cup on the instrument. Adjust the light modulating lever until
the meter pointer is steady at the zero "O" in the center of the scale. Always move the light modulating lever in the same
direction when zeroing the photocell comparator, when calibrating or testing, to eliminate errors caused by clearance in the
mechanical linkage. This may take 45 seconds. If the reading obtained on the scale located on the back of the Aqua Glo
instrument does not agree with the "set" number on the calibrating standard, adjust the photocell comparator on the side
of the instrument pack (at the 45 degree bend). Insert the included small screwdriver, and adjust as necessary. Repeat
the above procedure until the reading obtained agrees with the calibrating standard "set" number. THE INSTRUMENT
SHOULD BE CALIBRATED PRIOR TO EACH USE AND AFTER EACH HOUR OF USE.
Return the calibrating standard to its container in the kit. Do not use a calibrating standard from another kit. Each calibrating
standard is matched to a fluorescing standard which is secured under the panel labeled "Fluorescing Standard." The code
number on the Fluorescing Standard must be the same as the code number on the Calibrating Standard but the "set"
points need not be the same. Instruments that have been manufactured since 1998 have a small decal on the stationery
face of the hinge providing the code number. NOTE: We urge our customers to label older instruments accordingly so that
operators can easily determine if they are using the matching calibrating standard.
SAMPLE CONNECTION
The sample connection must be planned so that the flow path to the test pad is as short as possible and so that there are
no traps or pockets that may collect water.
