  • NU series - Network Communication Unit

    Compatible sensors are photoelecttric sensor PS-N series, fiber sensor FS-N series and laser sensor LV-N series.

  • FD-X series - Clamp-on Micro Flow Sensor

    The FD-X Series Clamp-on Micro Flow Sensor can be easily installed from outside the pipe and detect flow rates as low as 0.1 mL/min (and shot amounts as low as 0.001 mL). The device does not come into contact with the liquid, preventing problems such as pressure loss and clogging. The non-contact design also means the device is not affected by the properties of the liquid (ex. viscosity). Even coating/filling applications of grease, adhesives, flux, sealants, chemicals, and other liquids are possible with the FD-X series. The design also prevents pressure drops, enabling flow rate measurement with no adverse effects on equipment conditions, such as jetting and spraying functions. Also, this clamp-on technology means there is no pipe cutting or modification required.

  • FD-R series - Clamp-on Flow Meter

    KEYENCE's FD-R Series Clamp-on Flow Meter is designed for pipes as large as 8". Installation is easy and requires only a screwdriver. The device can be mounted to a variety of materials including stainless steel, iron, copper, PVC, and resin. Both flow and temperature monitoring is possible for a wide variety of liquids—from water (including pure water) to oil, chemicals, and high-pressure liquids—at temperatures between -4°F and +248°F. The device does not come into contact with the liquid, so there is no risk of liquid-based corrosion or degradation, reducing maintenance time and costs. The rugged metal construction includes an easy-to-read indicator light, and data can be recorded directly on the device. The IP69K enclosure rating and NEMA4X compliance make this sensor both highly reliable and convenient for indoor and outdoor use.

  • FL series - Sensing Guide Pulse Level Sensor

    The FL Series is the industry's first "sensing guide pulse" level sensor. The new TriSense technology allows for detection of any liquid while also automatically adjusting for both the external environment (ex. waves, foam, etc.) and condition of the probe (ex. build-up).
