Any uk supplier recommendations?

As ever, I dont want to spend fortunes but it costs what it costs

Might be worth speaking to Omega: https://www.omega.co.uk/prodinfo/ultrasonic-flow-meters.html
Not cheaper but UK based.

Have you thought of hiring one? Google finds many suppliers so could be available very quickly - next day.

Be careful using ultrasonic Flowmeter. Both Doppler and time of flight types need careful calibration against an accurate standard and operate within a tight window for both accuracy and repeatability.

Thanks for that, I am aware of the limitations and the accuracy required in this application

Wellll, maybe, it depends on what standard you want to measure to. If you have water at a known temp you know the speed of sound in it, so can set the transducers accordingly. You need to know the inside diameter of the pipe is you're done.
I have a Siemens one, pricey Germanic thing, but it works well.
