*Specifications are subject to change without prior notice.

Our clamp-on type Ultrasonic Flowmeter UL350 has enabled applications to piping in various kinds by enhancing the permeation property of ultrasonic wave.
“Time-Flight” type flowmeter is capable of measuring a flow rate of metallic and plastic piping ranging from 25 to 1000 mm in nominal diameter.
A detector (an ultrasonic sensor) is mounted outside an existing piping by clamping method, so that it does not get into contact with the measuring fluid at all, and there are no concerns about the mixture of solid material and metallic ion into the fluid, the corrosion
of sensor by chemical, and the pressure loss by installing the flowmeter.

Features

  • · 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.
