A versatile range of top or side installation, vertical float level switches offering 1, 2 or 3 switch actions per unit. Designed for alarm and control applications in water, oils and chemical storage tanks and process vessels using the proven magnet and reed switch technology. A permanent magnet is contained within the float which, being bouyant, moves up and down with liquid level change. Total float travel is restricted by stops to ensure positive magnetic linkage with the reed switch. Hermetically sealed reed switch contacts within the stem change over as the float passes. Switch operation is therefore a direct reading of liquid level eliminating electronic and mechanical transmission or calibration errors found in other systems. Typical applications are high and or low alarm and pump control. Materials in contact with the liquid and vapours include stainless steel, or polyophylene methylene floats. Stainless steel stems with top of tank terminal enclosure in aluminium. Stainless steel flange or screwed connections making for compatibility with most liquids. All FLS Series switches are manufactured in Measurement Resources Sydney factory, where we have the expertise and facilities to build standard and non-standard units all within a tight QA/QC environment
