Scully Water Detector
WB 100 Series Manual
O P E R A T I O N
The SCULLY WATER DETECTOR is used to locate and determine the quantity of water standing under petroleum
products. The unit does not detect "dissolved water", but only the free water collected at the bottom of storage containers.
The WATER DETECTOR produces an audible whistling signal when the tip of the probe is in an electrically conducting
liquid such as water. Most petroleum products are nonconducting liquids producing no signal when the probe is lowered
through them. This can be tested by touching a wet nger to the center electrode and shell of the probe at the same time.
Lower the probe all the way to the bottom of the storage container. If the alarm sounds when the probe is on the bottom,
raise it up slowly until the alarm signal stops. The distance the probe was raised off the bottom is the depth of the "water
bottom" in the storage container. The WATER DETECTOR will work in products from gasoline through #4 fuel oil.
CAUTION:
When using the WATER DETECTOR on storage tanks containing "high static" products such as jet fuels, allow suf cient relaxation time
after lling the tank before lowering the WATER DETECTOR probe into the tank as you would with any metal gauging tape.
B A T T E R Y R E P L A C E M E N T
The WATER DETECTOR is powered by a single 9-volt battery. No power is drawn from the battery except when the unit
senses water and produces its whistling alarm signal, hence the battery should last for at least a year of typical use. The
battery is accessed for replacement by unwinding all cable and removing a single screw on the hub of the cable storage
section of Model WB 100 G. Replace battery only with the following type: Energizer EN22. Other types of batteries will void
safety approvals, and Scully Signal does not suggest using them.
WARNING:
Batteries must be changed in an unclassi ed location only.
P R O B E & U N I T M A I N T E N A N C E
Occasionally, the WATER DETECTOR may refuse to stop signaling when the probe is removed from water. This condition
is caused by a lm of water across the black plastic insulator visible in the probe tip. This can be corrected by applying a
lm of grease to the black plastic around the center electrode. Silicone grease is excellent for this purpose, but "axle
grease" works well too.
Keep probe and cable wiped clean and dry when not in use. Replace battery inside by removing screw holding two halves
of unit together.
