Note: In the Royal Coffeebar it is possible to operate the machine directly from the fixed water
connection. The inlet valve is activated via the user programme (Chap. 3, Page 16).
A pressure reducer installed at the inlet point maintains an almost pressureless operation before
the pump.
However, a separate flow meter is used to measure the flow rate.
