Hello there,
I am currently working on a vibrating element densimeter.
Here is the principle: an element is putted at his resonant frequency thanks to a magnetic drive. If this element is imersed in a liquid, the vibration will vary with fluid properties.
In that way I would like to measure a liquid at low pressure (near to atmospheric), temperature of -161°C and density near to 500kg/m3. The viscosity is weak.
I could use a coriolis U tube densimeter which are well known for that, if it was on line mounted. But I need to immerse my sensor in a tank. (no fluid circulation is possible)
Here is the question:
I am wondering which structure of the element could be the best for this work.
A tube ? A tuning fork ? A rod ? ...
I hope you understood well my approximative english and will be happy to see all your ideas,
Many thanks in advance.
