CNG pressure gauge

Features:

CNG Pressure Gauge is an essential part of CNG vehicles, fixed on the intake valve between cylinder and pressure regulator to show the pressure of natural gas in cylinder. Through a gas pressure sensor inside, the gauge sends pressure signal to fuel changeover switch, so that the driver get to know the gas volume inside cylinder.
