- Gauge A displays the inlet water pressure from 0 to 1 MPa (145 psi).
Gauge B displays hydraulic oil pressure from 0 to 40 MPa. The default value of it made by manufacturer is 17
MPa (2466 psi). The water high pressure is figured out by using hydraulic oil pressure multiplied by 20.
Note: 1 MPa≈ 145 psi
