The DZM Water Flow Switch Sensor is a compact, reliable, and high-sensitivity flow detection device designed to monitor and protect CO₂ laser engraving and cutting machines. It ensures that water is continuously flowing through the laser tube, preventing overheating and extending the lifespan of your laser equipment.

Made from durable plastic material with a black corrosion-resistant body, this sensor is ideal for use in closed-loop water cooling systems. The DZM flow switch automatically activates or cuts off the laser when water flow is detected or interrupted, providing a critical safety feature for your setup.
