The operating principle bases on a free-floating magnetic piston, which responds only to the motion of fluid within the pipeline, not to static or system pressure. In the presence of fluid flow, controlled movement of the piston actuates an external hermetically sealed reed switch, thus producing the required signal which can be used to actuate audible or visual alarms as well as relays or other.Features:1) Housing material: PBT 2) Piston material: PVC or PBT3) Spring material: stainless steel SUS304 4) Retaining rings material: stainless steel SUS304 5) Operating pressure: 150 PSI max. 6) Temperature range: -10 - 80oC 7) Reed switch carry current: 1.5A8) Reed switch current: 1.0A max. 9) Reed switch voltage: 300V AC, 250V DC 10) Reed switch power rating: 70A11) Lead wire: AWG 22, to 18, 300mm length, UL1430, free lead wire 12) Flow range: 0.75L 1.0L min. 13) Set point accuracy: ±10% max. 14) Set point difference: 15% 15) Repeatability: ±2% max. 16) Mounting orientation (horizontal or vertical): as signal of flow direction 17) Mounting thread: FNPT.3/4",18) Adequate filtration and sealing19) Procedures should be used when mounting in flow line 20) The flow set point is adjustable, made in our company
