Product Overview

Description

FS51/52 LEFOO 1/2'' 3/4'' 1'' Baffle brass water flow control switch

        FS series liquid flow switch is designed for managing the flow changes when the liquid flows in the pipe, such as water, ethylene glycol or other non-hazardous liquids. When the liquid flow is higher or lower than the setting value, the single-pole double- throw contacts (SPDT) can get through one circuit and at meantime to break the other circuit. FS series liquid flow switch is commonly used for chain reaction or “no flow” protection.

Features 

Max liquid pressure: 1 MPa, can be used in multiple applications.

There are 3 stainless steel paddles, can be used in 25 to75mmdiameter pipe.

Number of paddles is changeable and length of paddle is trim-able according to customer requirements.

With additional 6" paddle, FS series liquid flow switch can be used in 100 to150mm diameter pipe

Adjustable flow setting, Users can set the flow value according to their requirements.

The cover of FS52 flow switch is fully enclosed. This structure is effective for electrical equipment against the water and dust. (A little condensation is allowed). As FS52 flow switch is indivisible and fully enclosed, a little condensation will not lead to electric leakage. For user convenience, FS52 flow switch has large room for wiring.

FS51/FS52 can also be provided with stainless steel connection, which is suitable for ammonia and other medium.
