Description
Function
1.
Vacuum- overpressure safety
valve
Mechanical valve that protects the tank against overpressure and
vacuum.
2.
Pressure sensor 1
(0-600 mBar)
Electronic transmitter that measures the pressure of the nitrogen
blanket at the top of buffertank 1.
3.
Pressure sensor 2
(0-600 mBar)
Electronic transmitter that measures the pressure of the layer of
water above the sensor including the pressure of the nitrogen
blanket in buffertank 1.
4.
Water overflow tube*
Tube through which water is spilled out of the tank when the water
level has become too high.
5.
Spray feed*
Pipe that is perforated at the underside through which heated water
is injected into the buffertank. The pressure sensor on the side of the
buffertank is always above the center of the injection pipe.
6.
Pressure sensor 3
(0-600 mBar)
Electronic transmitter that measures the pressure of the nitrogen
blanket at the top of buffertank 2.
7.
Pressure sensor 4
(0-600 mBar)
Electronic transmitter that measures the pressure of the layer of
water above the sensor including the pressure of the nitrogen
blanket in buffertank 2.
8.
Pressure sensor 5
(0-1600 mBar / 0-2500 mBar)
Optional installed electronic transmitter for buffertank 1 that
measures the pressure of the water column above the sensor
including the pressure of the nitrogen blanket. Sensor is used for
leak detection measurements or ELC configurations in combination
with additional buffer tanks.
9.
Pressure sensor 6
(0-1600 mBar / 0-2500 mBar)
Optional installed electronic transmitter for buffertank 2 that
measures the pressure of the water column above the sensor
including the pressure of the nitrogen blanket. Sensor is used for
