Measures heavy, light, heating oil, etc.

• Measures the microflow range with superior manufacturing technology.
• Good at measuring pulsating flow.
• Amplifier built-in magnetic sensor, which is strong against noise, is output in proportion to the flow velocity.
• Pulse output by open collectors or voltage pulse.
• Measures a wide range of flow rate with high accuracy.
• Simple structure due to the elliptic gears employed as a measuring principle.
• Capable of measuring various liquids.
• RoHS complaint (Complies with the RoHS directive to address the environmental issues.)
