Description

Honda HD350 Ultrasonic Level Meter transmitted from the sensor are reflected back from the measured object, and the distance is calculated based on the echo return time. This makes it possible to perform operations such as measuring the liquid level inside a tank or monitoring the remaining amount of materials in a tank.

Honda HD350 Ultrasonic Level Meter Features

Honda HD350 Ultrasonic Level Meter is a compact, lightweight level meter which includes sensor and display in one unit. Graphical display shows real time wave form in A-mode and it is useful for maintenance. Mask function can avoid noise interference.

Features

  • For screen mode can be selected
  • Large display is adopted for HD353-A (Display size : 50 x 25mm, 49% larger than HD350-A)
  • Mask function
    • Unnecessary signal can be eliminated from the received signal by manually.
    • Echo signal from existing structure positioned between sensor and target cause interference.
    • Mask function removes these unnecessary echo effectively.
  • Interface
    • Three interface methods are prepared for remote operation.
      • RS-485 (MODBUS protocol)
      • 4-20 ｍA current output
      • Contact points (relay output)
  • Low-cost DSP level meter
  • Graphic LCD display shows the A-mode waveform
  • Wide measurement range, from 0.3 to 10 m
  • When performing measurements, masking can be applied to objects positioned between the sensor and target
  • Remote operation is enabled with RS-485 ( MODBUS® protocol ), 4 to 20 mA current output, and alarm output contact points

Applications

  • Measurement of liquid, powder level in a tank
  • Measurement of water levels in lakes, ponds or rivers
