Model YF S201C water flow sensor switch Key features and benefits - G1/2 inch connection for easy integration with standard water line fittings - Transparent enclosure allows clear visual observation of the water flow - DC power supply compatibility from 5 to 15 V for stable, low-voltage operation - Specifically designed for use in water heater installations to support proper flow-based control - Clear color enclosure to simplify inspection and status verification Why you need this - Reliable flow detection: it provides a flow-based signal to control circuits in water heater systems, helping ensure the heater runs only when there is actual water flow. - Easy installation and retrofit: the standard G1/2" connection aligns with common piping, making it straightforward to install or replace existing sensors. - Simple monitoring and troubleshooting: the transparent enclosure makes it easy to observe flow status during setup, maintenance, or diagnostics without disassembly. - Safe, low-voltage operation: designed to operate from a DC supply within 5-15 V, compatible with many low-voltage control systems used in residential and commercial hot water setups. - Clear appearance: the model’s color and enclosure provide a clean, unobtrusive look in typical heater installations. Specifications at a glance - Model: YF S201C - Type: Water flow sensor switch - Connection: G1/2" thread - Enclosure: Transparent - Power supply: DC 5-15 V - Intended use: Specifically designed for water heaters - Color: Clear Typical applications - Residential electric water heater systems: use the flow sensor to provide a signal to the control circuit so the heater engages only when there is sufficient water flow. - Water heating installations with circulation loops: monitor flow to trigger appropriate control logic, helping prevent overheating or dry-running conditions. - Service and maintenance scenarios: the transparent enclosure enables quick visual confirmation of flow status during inspection or troubleshooting. Notes on installation and compatibility - Verify the G1/2" connection matches your piping fittings before installation. - Ensure your control circuitry can operate within the 5-15 V DC range specified for reliable performance. - The transparent enclosure is designed for visibility during setup and service; normal operation should still preserve enclosure integrity.
