LPG storage tank detection and alarm installation
②Install combustible gas detection alarms in tank areas, equipment sheds, and vehicle loading and unloading platforms. Combustible gas concentration measurement consists of concentration probes and controllers. The controller is placed in the control communication room and connected to the PLC controller through the RS485 bus. When one or more combustible gas concentrations exceed the standard, the controller will display an alarm, and display the gas concentration exceeding the standard value and the location where the gas concentration exceeds the standard, and at the same time drive the sound and light alarm at the corresponding position. The alarm limit value can be set in three levels from low to high by the user according to the actual situation and relevant standards within the range.
