Operating Principle
Unlike ordinary level switches that use a float for level detection, the
61F Floatless Level Controller uses electrodes to electrically detect
the liquid level. The following figures illustrate this simple operating
principle.
When electrode E1 is not in contact with the conductive liquid, the
electrical circuit is open, and no current flows between electrodes
E1 and E3.
Consequently, relay X does not operate. Relay X’s NC contacts
(normally closed, b in the figure) remain closed. However, when liq-
uid is supplied to the tank, so that the liquid contacts or immerses
E1, the circuit closes. Relay X operates, and electrical devices con-
nected to the NO (normally open, a in the figure) contacts of the
relay begin operation.
Ideal for level control of any conductive liquid
Both general-purpose and panel-use models
available
Incorporates an arrester for surge and induced
lightning protection
Wide range of models: Long-distance, high- and
low-sensitivity, two-wire, etc.
LED indicator for quick operation check
Conforms to EMC/IEC standards

A pump is usually connected to a contactor, which in turn is con-
nected to the Controller contact outputs. The Level Controller would
automatically operate the pump, to control the liquid level in the
tank.
However, in practice, with only two electrodes, ripples on the sur-
face of the liquid cause the Controller to jump and start, shortening
pump (and other equipment) life. This problem can be solved by ad-
ding another electrode to form a self-holding circuit. The additional
electrode, E2, is connected in parallel with E1, as shown below.
As shown in the above figure, when the holding circuit relay is ener-
gized, contact a
made through the liquid and the electrodes is then retained by E2
and E3, even when the liquid level falls below E1, as long as contact
a
When the liquid level falls below E2, the circuit made through the
electrode circuit opens, which de-energizes relay X, thus closing
the NC contact of X.
Operating as simply as it does, possible applications of the Float-
less Level Controller are virtually endless. Not only liquid level con-
trol is possible, but such applications as leakage detection, object
size discrimination, and many other problems may be solved by one
of the reliable 61F Floatless Level Controllers.

... Operation Internal Circuit 61F-GPN-V50 Water Leak Detector AC power source Operating Principle When the two conductive cores of the Sensor Cable are contacted by a liquid, a weak alternating current (as small max.) flows across the cores. This current is amplified to operate a relay. In practice, leakage will be detected if water drops are present be- tween the core wire and the Electrode (F03-15 Sensor Cable) or de- tecting section (F03-16 Sensor Cable) ...
