Flow Sensors

Choose the right flow sensor to monitor flow rates in your continuous flow applications

Gems Sensors offers a broad range of flow sensors that offer visual Indication, continuous sensing and accurate switching for use in liquids or gases. Trusted RotorFlow® flow sensors and turbine flow sensors feature high quality, corrosion-resistant materials for use in tough environments with material choices, ranging from stainless steel to Ryton for vast chemical compatibility. Both RotorFlow and turbine flow sensors utilize Hall Effect technology to produce a series of voltage pulses that provide a user with accurate and reliable flow measurements.
