Cng gas pressure gauge

ø summary

The cng gas pressure gauge is an important accessory for natural gas vehicles.Installed on the intake valve of the car cng pressure reducing regulator connected to the cylinder, the main function is to display the pressure of natural gas in the cylinder.The inside of the case is equipped with a gas pressure sensor, which can transmit the pressure signal to the oil and gas transfer switch in the cab of the car, so as to understand the capacity of the natural gas in the cylinder.
