Australia has seen an increase in CNG (Compressed Natural Gas) buses being introduced into modes of public transport over the past few years. Whilst CNG is considered a safer form of fuel than Diesel or LPG there are a few safety factors to be aware of.

4. System will be compact/discreet as space is limited.

Gas Monitoring System to detect CNG leaks
Gas Detection for
A leak on a CNG bus may occur at any time and in any location.
Early Detection of such a leak is essential.
Sensor 1 - CNG Pod
Sensor 2 - A/C Duct
Electrical control panel
Operators warning
Lamp and digital
data transmitter
The gas detector control unit is located behind the driver in the electrical control panel. There are two sensors fitted, one in the gas pod, the second sensor in the return AC duct inside ceiling of bus.
1. In the event of any gas leak the system will activate and provide instant notification.
2. A remote warning lamp will notify central control via the Motorola radio system.
3. System will have a test protocol for maintenance purposes.
Scope requirements
Gas detection capable of alerting at low levels of CNG.
System will operate within 24 to 30 volts DC to suit bus power.
Control unit is capable of up to 3 sensors.
Sensor and detector operating temperature range 0 to 60 degrees celsius.
System requires regular calibration.
