1L Min Adjustable Flow Switch ABS

A precision-engineered water flow switch calibrated to detect flows starting at 1 L/min, with user-adjustable sensitivity to accommodate diverse hydraulic system characteristics. Its core construction uses environmentally compliant ABS plastic—selected for balanced rigidity, thermal stability up to 100 ℃, and resistance to mechanical shock loads of ≥1 MPa. Electrical operation spans 10–100 V DC input, with safe interruption capability up to 250 V and 0.5 A load current. The built-in level sensor adds redundancy by verifying actual liquid contact—not just flow velocity—enabling safer dry-run prevention in booster pumps or timed fill sequences. Dimensions and mounting interface follow industry-standard footprints for easy retrofitting into existing metering or appliance platforms without custom brackets or adapters. Applications span regulated and consumer-facing systems: EN1434-certified gas metering modules, WRAS-compliant water meter assemblies, CE-marked coffee machine safety interlocks, and F-Gas-compliant HVAC condensate management—all benefiting from its repeatable trip point and low hysteresis design.
