  • The sensor of ultrasonic flowmeter UL350 is clamped on just outside of an existing pipe without any piping modification and time consuming installation work.
  • By adopting a DSP and an AD converters, the flow measurement has been speeded up, and the resistance to bubbles has been improved.
  • Because of the noncontact measurement method, the formation of bubbles and the mixture of metallic ion have been completely prevented.
  • Installing the flowmeter does not cause the pressure loss because of no obstacles in the measuring pipe.
  • The ultrasonic flowmeter is not affected by the pressure or conductivity of fluids.
  • Excellent in long-term stability because of no moving part.
  • Providing the following functions: Forward/backward flow rate display, totalizing display, analog output, pulse output, status output.
  • Capable of controlling the flow rate with digital data by RS-485 serial output. (Forward/backward flow rate output, totalizing output, and status output by the Modbus protocol)
  • A multi-drop connecting method has greatly reduced the signal wire.
  • Complied with RoHS. Applying for EMC standards.
