Liquid Level Controller
Type: EC - 4
◘ Applications:
☼ Drinking and non-Drinking Tanks
☼ Pressure and non-pressure vessels
☼ Water treatment plant
☼ Acid tanks
☼ Small steam boilers
☼ Hot water boilers
☼ Fuel Tanks
☼ Desecrators
◘ Function:
Change of liquid level, causes movement of floating capsule. Movement of
the floater is transferred through a connecting rod, to the magnet placed at
the end of the rod and causes its displacement. Inside the controller, there
is another magnet along with a limit switch at the back of the flange. The
movement of the floater causes operation of the limit switch through
interaction between the two magnets. Required commands are sent to the
electrical circuits for controlling alarms and machines like: pumps,
solenoids and electromotor through operation of the limit switch.
◘ EC - 4 Type advantages:
1) This instrument is installable with more safety due to non - relation
of mechanical or electrical connection between the parts inside the liquid
and outside it.
2) Floating range can be adjusted by changing the placed of the provided
pines.
3) Fluctuation or instant waves don't cause circuit to open or close.
4) All parts inside liquid are made of stainless steel and have durable.
5) This instrument is thoroughly sealed against penetration of water. To
avoid gas penetration, please contact with manufacture.

◘ Installation:
Special flange which is made by company is placed previously in exact
determined location on usable tanks. Level controller is installed by bolt
and nut from related flange directly on above place in accordance with (Fig.
C). In tanks which their pressure is 16 bar special flange PN - 16 have to
used.
Note: The arrow on the level controller in installation place is
toward up.
