Ultrasonic level meters

หมวดหมู่ : INSTRUMENTS TOKYO KEISO Level Measurement Level Gauges

แบรนด์ : TOKYO KEISO



  • on-contact and continuous level measuring
  • Measuring for versatile fluids and solids like liquids, slurries, powders, granules, pellets, gravel etc
  • High power sensors make it possible to measure as high as 60m height of powders
  • The built-in temperature sensor compensates sound velocity change automatically to assure the accurate measurement
  • Selectable 2-wire looped power or AC/DC power supply, and integral or remote type depending on your applications and installation conditions
  • Provided with amplifying function to keep high signal/noise ratio and function to eliminate the influences from reflection-from-obstruction, UW5000s are used for many challenging applications
  • Outputs of level, distance, volume, difference of two sensors and average of measured values
  • The AC/DC power supply type has maximum 5 points contacts for such applications as pump control
  • RS485 communication equipped with standard function serves for remote data acquisition and remote setting with PC with dedicated software
