Paddle Wheel Flow Meters Switches

Paddle wheel and Pelton wheel flow meters are types of mechanical flow meters that measure the flow rate by the rotational speed of a wheel placed in the liquid stream. These meters are well-suited for measuring the flow of clean, low-viscosity liquids. Their simple design makes them cost-effective and easy to install and maintain.

Paddle wheel and Pelton wheel meters can also provide a visual indication of flow. While their application is limited by liquid cleanliness and viscosity, these flow meters remain a popular choice for simple, economical flow measurement solutions.
