Paddle Wheel Flow Meters Switches

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.
