Need to measure flow of oil at high pressure!!

[tommy5]

Hi all,

I have an application where I need to measure oil of about 1000 centipoise, through a 1/4" pipe. The pressure is roughly 450bar and I have calculated the flow rates to be in the region of 3 to 3.6 litres/min.

I have been looking at oval geared meters but can only find ones that go upto 50bar!!

The viscosity is way to high for a turbine meter, and the budget I have been give is know where near high enough for a coriolis meter.

A 0-10v or a 4-20mA output as well as a local display is required.

oh.. forgot to mention the temperature is roughly 80C.

Any help would be appreciated!

Hi,

You should take a look at this specialist UK flow measurement forum thread on QZONE

We found a model for a similar application from Bell Flow and it is cheap as chips.

good Luck

Here is one of several types of oval gear meters that we used in our process.

Kral meters perhaps?

the high pressure will operate to 420bar, according to the brochure but perhaps they can supply a unit for even higher pressures?

Hi, Thanks for the input!

I ended up speaking to Bell Flow Systems and have now got one of these on order

http://www.bellflowsystems.co.uk/G2-~-1-4-LIQUID-FLOW-METER-pr-19156.html

with a display that will give me the local reading and a 4-20mA ouput which is great news.

They were very helpfull and hopefully a solution should be installed soon

Thanks.
