PRESTONICs presents the DK-FS-001 Flow Sensor manufactured by DK Sensor, an integrated fluid-tracking module engineered for highly accurate, constant flow rate evaluation. Fully optimized for professional “Design-in” engineering and high-volume OEM assembly, this robust sensor delivers the exceptional calibration stability and Project Protection required for modern liquid-dispensing and cooling hardware.
The sensor is strategically configured with a high-performance mechanical and electrical architecture to provide precise, real-time volumetric data:
High-Fidelity Impeller Mechanism: Employs an internal fluid-driven impeller that rotates an integrated magnet across a Hall IC switch, generating an exact digital frequency output corresponding to real-time flow.
Tight-Tolerance Flow-to-Frequency Mapping: Delivers exceptional metering accuracy, offering a resolution of 0.513cc/Hz with a tight ±3.5% tolerance across its primary 0.5 LPM to 4.0 LPM usable flow range.
Heavy-Duty Hydrostatic Endurance: Specially built to withstand high structural pressures, maintaining reliable operation under hydrostatic water pressures ranging from 0.5 to 8.5 kgf/cm².
Acoustically Insulated Noise Profile: Engineered for silent performance inside premium consumer appliances, maintaining an ultra-low operational noise level of 20dB(A) or less at a 150mm distance.
Broad Thermal Fluid Versatility: Capable of processing standard tap water or mineral water across a demanding liquid temperature spectrum ranging from 5°C up to 95°C.
Technical Specifications Summary:
Operating Voltage & Power Rating: DC 5V operating voltage with a flexible DC 3.5~24V power rating range.
Current Consumption: Max 15mA Hall IC opening current.
Flow Metering Resolution: 0.513cc/Hz ±3.5% (0.5 to 4.0 LPM) / ±7.0% (0.4 to 4.9 LPM).
