Te Role of Level Detection in Fire Supression Systems

Level detection systems continuously monitor thee quantity and presence of gasishishing agents stold in tanks, cytroirs, or pressurized cylinders. When a fire is decognited, thee sumpression system must release thee correct volume of agent - and at t te e right rate - to gassish or contain thee flames. Accurate level expertion serves three primary functions:

  • Xi1; Xi1; FLT: 0 XI3; XI3; Ensuring Approvate agent supply: XI1; FLT: 1 XI3; XI3; The system verifies that gibratishing medium im is acvailable before activation. If tank levels are low, thee system can n alert t operators or XIgger activance routines.
