PP Paddle Wheel Flow Sensor Main Functions
Superior PP Material Performance. All wetted parts constructed from high-grade PP, providing excellent resistance to weak acids, alkalis, and most aqueous solutions.
Lightweight yet durable, with high impact strength and resistance to fatigue cracking in continuous flow applications.
Non-toxic and non-contaminating, suitable for drinking water and general industrial water systems.
Wear-resistant ceramic shaft and bearings minimize friction, reducing maintenance and extending service life.
IP68 defense applies to any serious field working environment.
Low maintenance requirements with wear-resistant ceramic bearings, reducing long-term operational costs.
The maintenance-free design makes you more convenient and assure
