SCHEMATIC DIAGRAM MP5N/MP7 CLOSED TANK
On these units, there may be 1 or 2 pressure control valves.
Same principle than open tank system except that the water level is calculated from the water weight inside
the tank. For this, a weight sensor is connected to an electronic card inside the control box. This card power
supplies the weight sensor and acquires its signal, translated into inner water level, replacing the standard
water level sensors.
