Pressure Monitor
The number of double-speed section errors in each measurement can be indicated.
A double-speed section error indicates that the pressure did not return to the reference level
(previous pressure) even after double-speed control (an increase of pump motor speed) was
effected to compensate for a pressure drop. This may be caused by formation of air
bubbles in the flow path.
