{"product_id":"lf-series-mass-flow-leak-tester","title":"LF Series - Mass Flow Leak Tester","description":"\u003cdiv class=\"fgt-product-desc\"\u003e\n\n  \u003cp class=\"fgt-lead\"\u003eThe LF Series measures actual volumetric flow rate under controlled pressure conditions — making it the right instrument when you need to verify flow characteristics, not just the presence or absence of a leak. It is widely used for medical tubing, breathable membranes, micro-valves, and any application where a specific flow range defines product acceptability.\u003c\/p\u003e\n\n  \u003ch2\u003eHow It Works\u003c\/h2\u003e\n  \u003cp\u003eThe test part is pressurized to a stable setpoint. The LF's mass flow sensor then measures the steady-state volumetric flow through (or from) the part. Results are expressed in L\/min or sccm. Upper and lower flow limits define the OK\/NG window — parts that flow too freely (excess leakage) or too restrictively (blocked path) are both rejected. Unlike pressure decay methods, the LF directly characterizes the flow behavior of the part regardless of internal volume variations.\u003c\/p\u003e\n\n  \u003ch2\u003eKey Specifications\u003c\/h2\u003e\n  \u003ctable\u003e\n    \u003ctr\u003e\n\u003cth\u003eParameter\u003c\/th\u003e\n\u003cth\u003eSpecification\u003c\/th\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eTest pressure range\u003c\/td\u003e\n\u003ctd\u003e0 – 1200 kPa\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eSensor accuracy\u003c\/td\u003e\n\u003ctd\u003e0.1% FS\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003ePower supply\u003c\/td\u003e\n\u003ctd\u003eAC 220 V ±15%, 50 Hz, 60 W\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eDimensions\u003c\/td\u003e\n\u003ctd\u003e320 × 284 × 300 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eWeight\u003c\/td\u003e\n\u003ctd\u003e8 kg\u003c\/td\u003e\n\u003c\/tr\u003e\n      \u003ctr\u003e\n\u003ctd\u003eDisplay\u003c\/td\u003e\n\u003ctd\u003e7-inch color touchscreen · 4-stage auto test cycle\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eCommunication\u003c\/td\u003e\n\u003ctd\u003eRS-232\/485, USB, Ethernet, PLC I\/O\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eAir supply pressure\u003c\/td\u003e\n\u003ctd\u003e0.4 – 0.8 MPa\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eOperating temperature\u003c\/td\u003e\n\u003ctd\u003e0 – 50 °C\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eCycle time\u003c\/td\u003e\n\u003ctd\u003eConfigurable; application-dependent (typical production cycle ≤ 20 s)\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eOperating humidity\u003c\/td\u003e\n\u003ctd\u003e≤ 95% RH (non-condensing)\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eCertifications\u003c\/td\u003e\n\u003ctd\u003eCE Marked · ISO 9001:2015 · National High-Tech Enterprise\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\n\n  \u003ch2\u003eModel Selection\u003c\/h2\u003e\n  \u003ctable\u003e\n    \u003ctr\u003e\n\u003cth\u003eModel\u003c\/th\u003e\n\u003cth\u003eFlow range\u003c\/th\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eLF-1005\u003c\/td\u003e\n\u003ctd\u003e0 – 5 L\/min\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eLF-1010\u003c\/td\u003e\n\u003ctd\u003e0 – 10 L\/min\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eLF-1020\u003c\/td\u003e\n\u003ctd\u003e0 – 20 L\/min\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eLF-1030\u003c\/td\u003e\n\u003ctd\u003e0 – 30 L\/min\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eLF-1050\u003c\/td\u003e\n\u003ctd\u003e0 – 50 L\/min\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003c\/table\u003e\n\n  \u003ch2\u003eTypical Applications\u003c\/h2\u003e\n  \u003cul\u003e\n    \u003cli\u003eMedical IV tubing, catheters, and drug delivery micro-channels\u003c\/li\u003e\n    \u003cli\u003eAutomotive in-cabin refrigerator capillary tubes\u003c\/li\u003e\n    \u003cli\u003eBreathable and waterproof membranes (PTFE, Gore-Tex equivalents)\u003c\/li\u003e\n    \u003cli\u003eCopper and aluminum capillary tubes for HVAC and refrigeration\u003c\/li\u003e\n    \u003cli\u003eMicro-valves requiring specific flow resistance characterization\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003ch2\u003eWhy LF?\u003c\/h2\u003e\n  \u003cul\u003e\n    \u003cli\u003e\n\u003cstrong\u003eDirect flow measurement:\u003c\/strong\u003e Not affected by internal volume variability — measures actual flow, not inferred leakage\u003c\/li\u003e\n    \u003cli\u003e\n\u003cstrong\u003eValidates both ends of the spec:\u003c\/strong\u003e Catches over-flowing (leaking) and under-flowing (blocked or restricted) parts simultaneously\u003c\/li\u003e\n    \u003cli\u003e\n\u003cstrong\u003e5 range options:\u003c\/strong\u003e Match the sensor to your expected flow window for maximum resolution\u003c\/li\u003e\n    \u003cli\u003e\n\u003cstrong\u003eMedical-grade accuracy:\u003c\/strong\u003e Used in ISO 11608-validated catheter and drug packaging test lines\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003cp\u003e\u003cem\u003eSpecify your required flow range and target pass\/fail window when requesting a quote.
