WFS-1001-H – Paddle Type Flow Switch – A Cost-Effective & Efficient Solution for HVAC Systems
Posted on: 09/08/2025
In HVAC systems (Heating, Ventilation, and Air Conditioning), accurately controlling the flow rate plays a vital role in ensuring operational efficiency, saving energy, and prolonging equipment life.
The WFS-1001-H model – paddle type flow switch – is one of the optimal solutions trusted by engineers in commercial and industrial projects.
1. What is WFS-1001-H?
WFS-1001-H is a mechanical paddle-type flow switch that operates based on the principle of a paddle being pushed by fluid flow. When the flow reaches a certain level, the paddle activates an internal contact, switching the signal on/off for connected systems such as water pumps, solenoid valves, controllers, alarms, etc.
