Technical Specifications1. Gas Fuel Level Gauge (Pressure Gauge)
It is a pressure gauge which not only can show
the gas pressure about the gas-cylinder and the
high-pressure pipe, but also can transform the
pressure into the electric-signal to the switch on
the front panel, so that remained gas displayed.

2. Sensor Electric Circuit
The electric circuit of our product is HOLL magnetic induction circuit. It transforms the pressure into the voltage signal. They all have
the excellence of high precision, reliability and durability.
Voltage of the supply: DC12±2V
Way of wiring: three wire of red, black, yellow. Red one is the power wire, black one is the iron-connection wire, yellow one is the voltage-signal output wire.
