The Matheson Pressure Monitor, Model PM-24, was designed as a method of monitoring a gas supply, when used in conjunction with Matheson Gas Delivery Systems with Indicating Pressure Switches (IPS). The PM-24/IPS will indicate the status of both sides of the switchover: FULL – IN SERVICE, and DEPLETED. When a cylinder or cylinder bank is depleted, the green light will change to a red light, and the audible alarm will sound. The audible alarm can be silenced, leaving the red light indication. The red light will automatically reset to green when the depleted cylinder is replaced with a full cylinder.
