Hoyles LFS1 Water Extinguisher Filling System

he Liquid Fill Switch is a unique microprocessor controlled flow switch that dispenses an accurate amount of water on a repeat basis for batch filling of extinguishers. The initial learning cycle is controlled by the reset and fill buttons. Once the volume required has been learnt by the unit it is stored in memory. Each subsequent fill is then an accurate repeat volume of this first fill. The unit can be reset to dispense a different amount easily and quickly using the front panel reset and fill buttons. The unit is supplied with an inlet and outlet flexible hose for connection via standard 19mm BSP connectors.
