• NOTICE:1.Severe impact, chemical corrosion, dropping and collision are strictly prohibited. 2.The temperature of the flowing medium must not exceed 120 degrees Celsius.
• This water flow sensor is mainly installed on the water inlet to detect inflow rate. It is widely used in water coolers, coffee machines, water purifiers and other equipment.
• This product features a lightweight, compact design for easy installation. It is fully encapsulated with potting glue to prevent water ingress and leakage.
• The impeller is embedded with a stainless steel shaft running through its top and bottom. This distributed load design reduces concentrated stress points and delivers superior wear resistance.
• Water inlet: inner diameter 2 mm, outer diameter 7 mm.Designed to connect with 6 mm soft hose .Thread length: 15 mm.
