High temp clamp on flow meters

[Mechanical Farmer]

Looking for recommendations for a clamp on flow meter for polymer melt. Prefer adjustable from 1" to 4" pipe size and non nuclear.

Define "high temperature".

Proline Prosonic Flow P 500 ultrasonic clamp-on flowmeter

The proven sensor Prosonic Flow P can be installed close to elbows, expansions or constrictions in the pipe and still maintain the same measurement accuracy. Even measurement of abrasive, corrosive or toxic fluids is no problem for the non-invasive clamp-on device. Prosonic Flow P 500 is mounted...

Check with them, E&H and ask for a trial, unless they have experience with your product.

My 2 cents,

The biggest issue with UT clamp on meters will be the lubricant or coupling between sensor and pipe. But probably also need to check if the fluid is able to be measured that way depending on its sound attenuation.

what have you looked at so far?

Corriolis meter is prob best, but isn't a clamp on.

I'm just exploring, I was looking at the E+H Pierre mentioned above but that was just based on a quick google search. We've also looked at Vega Minitrac, but no everyone is comfortable with the idea of radiation.
I've asked my instrumentation guy for suggestions. This is for a special project so I wanted to come to the table with some suggestions before approaching him.

I was looking at this one. I didn't know there was the opportunity for testing. I've asked if my instrumentation guy has an account with them.

Fair enough but you need to answer the question about temperature and why you need clamp on and whether ultrasonic will work in your fluid.
