water flow sensor designed for reliable, precision flow measurement in domestic and industrial water systems. The impeller uses a stainless steel shaft for wear resistance, while the Hall effect sensor provides accurate, contact detection. A mechanical seal ring ensures leak operation under varying pressures and temperatures. RoHS compliant and corrosionresistant for long service life. Key features precision and fast response with stable performance across a broad flow range. Durable construction: stainless steel shaft, corrosionresistant materials, RoHS compliant. Leakproof seal: mechanical design resists leakage from both directions and stress. Easy installation and maintenance: compact inline design, simple mounting and removal. Applications and compatibility Suitable for water heaters, gas wallhung boilers, electric water heaters, floor heating, circulating water systems, water control machines, instrumentation, and other mechanical equipment. Practical use scenarios Residential and commercial water heaters or boilers to monitor flow and protect against unsafe operation. Floor heating and radiant heating systems to regulate pump activity and maintain consistent temperatures. Instrument panels and water vending machines requiring reliable, accurate flow metering.
