Learn about the different types of flow meters and monitors.

With so many different options and price levels, it can take a good understanding of flow meters and the desired application to truly identify the product you need. Below is a short breakdown of the various types and how they can be used.

Variable Area: Durable flow rate monitor with optional switch and/or transmitter. Could be an indicator, switch, transmitter or all types in one.

Thermal Switch: Flow switch with no moving parts that's ideal for fluids containing contamination or debris.

Sight Flow: Entry level flow indicator allows you to see the flow moving and passing through. Typically indicator only.

Rotameter: Inexpensive option used for flow indication for water, oil and air. Typically indicator only.

Turbine: Affordable and accurate flow measurement used for liquids. Can be a flow meter, transmitter, indicator or totalizer.

Paddle Wheel: Low cost flow rate indication and totalizer for light viscosity fluids. Provides a transmitted output signal and can be a flow meter, indicator, transmitter or totalizer.

Rotameters, Variable Area, Paddle Wheel and Turbine at great prices.
