  • Bespoke Ultrasonic Flow Measurement Solutions & Problem Solving
Benefits of the Atrato Ultrasonic Flow Meter
  • High reliability
  • No moving parts
  • Fast response
  • Through bore design
  • Easy to use
  • OEM versions

Utilising patented technology that enables it to operate with excellent accuracy over very wide flow ranges, across the whole span, the Atrato range of inline ultrasonic flow meters is a genuine breakthrough in flowmeter technology.

Its rugged, clean-bore construction makes the Atrato ideal for a whole range of low flow applications and its USB port allows software connectivity at literally the touch of a button. Its signal processing system permits flow measurement across the whole Reynolds number range allowing both viscous and non-viscous products to metered accurately, whilst signal discrimination identifies anomalies in the flow and generates reports as required.

The Atrato Ultrasonic Flow Sensors – Applications

The Atrato Flows from 2mL /Min to 20 L/Min.

The Atrato ultrasonic flow sensors deliver a step change in flow meter performance in a wide range of applications. It can handle low flows from luminar to turbulent and is largely immune from viscosity. It has excellent turndown, repeatability and linearity and can monitor flow over a range of 200:1. Accuracy is better than +/-1.5%, which makes it ideal for:

ultrasonic flow sensor applications

Atrato Ultrasonic Flow Indicators: Features

Heritage of Atrato Ultrasonic Flow Indicators

The development of Atrato ultrasonic flow indicators began in 2001 with a corporate decision to develop the best noninvasive small bore flow meter in the world as part of a long term strategic plan. One of the foremost fluid engineering establishments (The Cranfield Institute of Technology) was commissioned to develop the device along with Titan and this joint project has been continuous since that date. Titan have exclusive global rights for the technology which is subject to two granted patents and two more applications will be made in the near future.
