Fixed Weight Monitoring for Fire Suppression Systems

Cylinder agent leakage can cause an entire fire suppression system to malfunction, and if undetected could result in an ineffective release of agent that may fail to extinguish a fire. A catastrophic leakage event that dispels entire contents of a cylinder is immediately apparent; however, slow leakage over time is very hard to detect. Slow leakage resulting in a 10% decrease in CO2 agent mass requires complete replacement of the system and 5% if using clean agents or Inert gas systems. Therefore, it is imperative to be aware of slow leakage to allow maintenance to take place before a failure occurs.

The PermaMass® FEATHERWEIGHT is our innovative answer to the need for continuous Inert Gas, CO2 and Clean Agent cylinder contents monitoring. We recognise the need for continuous asset protection and monitoring and having one master control unit to display the constant agent weight fluctuation in high-pressure gaseous system installations, covering up to twelve cylinders is industry leading. Merging fundamental mathematics to enable true constant monitoring along with cutting edge engineering that could be easily retrofitted, bringing you our latest addition to the complex continuous monitoring technology.

Monitoring the mass of your cylinder contents is a fundamental way of measuring agent loss, against the risk of accidental discharge or slow seepage of agent and is the only method that is not affected by pressure or temperature. This enables cylinders to be constantly monitored 24/7 with the PermaMass® FEATHERWEIGHT to ensure they are at designed capacity, but we also provide real-time information on the exact amount of agent in the cylinders to less than 1% accuracy above 10 kg agent weight or 100 g below.

During a leak event, the system will show you the exact amount of agent loss, including percentage loss in each cylinder, and if monitoring Inergen™, it will show pressure loss, which is intrinsically linked to mass, all displayed on a full-colour 4.3” display.

“Technology that is designed for total flood fire suppression systems in high-pressure seamless cylinders.”

1. Monitors up to 12 cylinders (48 by connecting four main units together using one power source).
2. Accurate to 10 g or better than 1% above 10 kg total cylinder weight.
3. Converts mass loss in Inert gas systems into equivalent pressure loss.
