NDFlow Sensor

ND Photo

Features

The ND-type flow sensor has the measuring principle of impellers and is suitable for measuring various types of liquid. It is one of our best-selling products with high quality at a low price.

・Excellent repeatability
・Amplifier built-in magnetic sensor, which is strong against noise, operates in proportion to the flow velocity.
・Pulse output by open collectors.
・Measures a wide range of flow rate with high accuracy.
・Simple structure due to the tangential flow impeller method employed as a measuring principle.
・Capable of measuring various liquids.
・CE certified product
・RoHS compliant (Complies with the RoHS directive to address the environmental issues.)
