Описание

water level classification through upper and lower pools of water tower

of high-rise buildings. It can effectively prevent pool drainage, water overflow by automatically water supplement or decrease,

absolutely prevent the pump from damaged. It is very suitable for the water supply project on water towers or wells in

schools, industrial and mining enterprises from urban or rural. More, it is

widely used in printing, chemical, food, beverage, wine, sugar and so on.

Technical Specifications

Probe Installations

(I) Single-control UP pool (water storage) installation instructions shown in figure 1.

A(red)—Upper water level control point. When water level gets to A point,

the probe touch water and controller can stop the pump by auto.

B(blue)—Lower water level control point. When water level gets off B point,

the probe out of reach water and controller can start the pump by auto.

C(black)—Should be placed in bottom of pool as the common line.

D(green) and E(yellow)are connected with C (black).

(II) Single-control DOWN pool(drain water)installation instructions shown in figure 2.

E—Upper water level control point. When water level gets to E point,

the probe touch water and controller can start the pump by auto.

D—Lower water level control point. As liquid level gets off D point,

the probe out of reach water and controller can stop the pump by auto.

C—Should be placed in bottom of pool as the common line.

A&B—disconnected

(III) Lack of water protection installation instructions shown in figure 3.

C&D—Lower water level control points. When water level gets off this point,

C or D probe out of reach water and controller can stop the pump by auto.

E&C—short-connected

A&B—disconnected

(IV) Joint control UP and DOWN pool installation instructions shown in figure 4.

A—Upper water level control point in UP pool. When water level gets to A point,

the probe touch water and controller can stop the pump by auto.

B—Lower water level control point in UP pool. When water level gets off

A point, the probe out of reach water and controller can start the pump by auto.

C—Should be placed in bottom of UP and DOWN pools as the common line.

D—Lower water level control point in DOWN pool. When water level gets off D point,

the probe out of reach and controller can stop the pump by auto.

E—Upper water level control point in DOWN pool. When water level gets to E point,

the probe reach water and controller can start the pump by auto. Then pool starts to drain water. If not, E point disconnected
