Breakthrough Ultrasonic Flow Meter Technology & Proven Titan Pedigree

With over 40 years experience in flowmeter innovation and manufacture,
Titan’s company philosophy of “pushing the envelope by trying to do
things a little different and better” has resulted in sales of over 500,000
products into 50 countries worldwide and a repeat purchase percentage of
95% – something which Company founder Trevor Forster is justly proud of.

Today Titan supplies innovative flow measurement solutions into a broad
range of sectors, including medical, industrial, food & drink, laboratory and
pharmaceutical. Its latest innovation, the Atrato flowmeter range, is set to
challenge conventional flowmeter thinking the world over. The culmination of
eight years research and development in collaboration with the Department
of Process & Engineering at Cranfield University, it can handle low flows from
laminar 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 +/-1.0%.


Heritage of the Atrato Ultrasonic Flow Meter

The Atrato is the culmination of eight years research and development in collaboration with the Department of Process & Engineering at Cranfield University. 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%.

The development of the Atrato 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.

“The use of low frequency ultrasound and advanced signal processing to interrogate the flow ensures that the flowmeter provides high accuracy over a wide turndown range. In addition the technology developed for the Atrato has the flexibility to provide the basis of a family of flowmeters suitable for an even wider range of flows and applications.” Professor Mike Sanderson, Emeritus Professor of Fluid Instrumentation, Cranfield University


About Atrato Ultrasonic Flow Measurement

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 flowmeters 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.

How Atrato Ultrasonic Flow Measurement Works

The Atrato ultrasonic flowmeter system uses the well proven time of flight measuring method which is far more reliable and accurate than Doppler shift measurement where reflected signals are required from irregularities in the liquid. The Atrato crystals are plain disks with a hole in the centre forming a washer, which are excited in such a way that they oscillate radially as opposed to the normal mode of excitement which is across the thickness of the ceramic. This strong radial signal sends symmetrical pulses directly into the tube.

Because of these annular ring crystals the sound travelling down the liquid
can be considered as a plain wave. The signal to noise ratio is remarkable
as there is little background noise and high signal strengths. At times the
signal to noise ratio is as high as 3000:1. As the system is fully balanced at
zero flows the two signals are identical and cancel each other out. This gives
a very stable zero flow condition and is the basis of the Atrato’s high ratio
between minimum and maximum flows. As the flow increases these signals
go out of phase and we measure this phase shift to an accuracy equivalent to
250 picoseconds.

In addition, the sound waves travelling down the tube in the Atrato operating
system are symmetrical and as a result any changes in the fluid’s velocity
profile across the pipe diameter will be averaged out by the signal as it passes
from the transmitter to the receiver. It is therefore irrelevant whether the fluid
velocity profile is fully formed with turbulent flow or completely laminar with a
classic parabolic profile. In practice this gives the Atrato an excellent immunity
to Reynolds number changes and a good high viscosity performance.

A Powerful Measuring System – Ultrasound Flow Measurement

The time of flight measuring system measures both the upstream and downstream flight times and half the difference is the velocity of the fluid. Our patented system measures these time differences to an accuracy of better than 250 pico-seconds giving our excellent meter performance. As the pipe geometry is known the resulting pulse output is accurate for the volume passed. This performance is further enhanced by our primary signal to noise ratio which is typically 2000:1 and at times as high as 3000:1.

The Atrato time of flight flow measuring system is state-of-the-art, breakthrough flow measurement technology
