Overview

The CUCIR High-Precision Micro Flow Series offers professional-grade sensing solutions for low-flow environments. Designed with high-sensitivity internal architecture, these sensors provide selectable measurement ranges of 0.05–1 L/min and 0.3–4 L/min with an impressive accuracy of ±3%. Even under ultra-low flow conditions, the sensor maintains consistent and stable pulse output. This series is the ideal choice for precision metering in water heaters, smart water control systems, and automated dispensing equipment.

Feature

Precision Low-Flow Performance: Engineered for high sensitivity, the sensor achieves ±3% accuracy and remains stable even at the threshold of minimal water flow, ensuring reliable data for delicate applications.

High-Stability Pulse Output: Delivers a clean, consistent pulse signal directly proportional to the flow rate. The distinct low-level signal facilitates precise quantitative dosing and accurate cumulative flow statistics.

Ultra-Low Power & Wide Voltage Design: Compatible with a wide power supply range of DC 3.5–24V. With a maximum operating current of just 15 mA (at DC 5V), it minimizes power consumption and thermal interference in sensitive electronic systems.

Industrial-Grade Reliability: Built to withstand a maximum pressure of 0.8 MPa. The sensor operates reliably across a temperature range of 0–80°C and humidity levels up to 90% RH, meeting the rigorous standards required for home appliances, water treatment, and industrial monitoring.
