Turbo Boost Gauge: Description and Operation
Boost pressure gauge consists of a manometer which indicates lower and higher pressure in the inlet pipe. In the case of normal pressure, when the turbo
pump provides neither low nor high pressure, the gauge needle should be vertical. High and low pressure are indicated to the right or left of the vertical
respectively.
The range lies between:
-1 bar (15 lbf/Sq.in) to +1 bar (15 lbf/Sq.in).
Boost pressure gauge is connected by means of a hose to the inlet pipe.
