*Specifications are subject to change without prior notice.

UL330R is a “Time-Flight” type clamp-on ultrasonic flowmeter and capable of measuring a flow rate of plastic piping (PVC, PE) ranging from 25 to 300 mm in nominal diameter and stainless steel piping ranging from 25 to 400 mm 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 UL330R 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.
