Overview

The stainless steel flow sensor offers two flow range options: 5–150 L/min and 10–200 L/min. It supports DN40 and DN50 connection specifications, making it compatible with various piping systems. The flow sensor delivers highly stable pulse signals with a clear pulse coefficient, maintaining error control within ±5%. Constructed from high-quality stainless steel, the valve body offers excellent corrosion resistance and mechanical strength, ensuring long-term stable operation within a medium temperature range of āˆ’20 to 100°C. It is suitable for clean water applications.

Feature

Stainless steel flow sensor feature

  • Wide flow coverage supports DN40 and DN50 interface specifications. The optimized inner diameter design effectively reduces flow resistance, meeting stable flow measurement requirements for industrial and equipment applications.
  • The flow sensor delivers highly stable pulse signals with a clear pulse coefficient, maintaining error control within ±5%. This enables precise measurement at approximately 27 or 12 pulses per liter.
  • Constructed from high-quality stainless steel, the SUCH flow sensor offers excellent corrosion resistance and mechanical strength, making it suitable for applications demanding high reliability.
  • Supports a wide 3.5–24 VDC power supply range, with insulation resistance exceeding 100 MĪ©. Clear pulse high/low levels and simple installation wiring enable rapid integration into various control systems.

FAQ
āÆ

Typically featuring a 304 or 316 stainless steel housing, this flow sensor offers excellent corrosion resistance and pressure tolerance. It is suitable for measuring water, aqueous solutions, weak acids/alkalis, and certain industrial fluids. It is widely used in water heaters, equipment integration, and industrial control systems.

āÆ

Compared to plastic materials, stainless steel flow sensors can withstand higher operating temperatures and pressures, making them suitable for hot water, circulating water, and pressurized pipelines. When operated within specified parameters, they maintain long-term measurement stability and structural integrity.

āÆ

Ensure correct flow direction during installation. Avoid air bubbles or impurities impacting the sensor within the pipeline. Install according to the recommended straight pipe section requirements to guarantee measurement accuracy and sensor longevity.
