I need to measure liquid level inside a sealed container there can't be placed any sensors inside it. This is a shock absorber in a very powerful machine. So in operation the pressure and temperature will be high and flowing speed of liquid is also high .
1. Container is steel cylinder, height 1 meter, diameter 8 inches, wall thickness 3 mm. it can be tilted horizontal to 60 degrees in vertical. But can't be moved. It contains a nother hollow steel cylinder.
a. This small cylinder is same height, diameter 5 inches. And have a orifice of 5 cm on its wall so liquid can move in and out from this cylinder to outer cylinder freely.
I will be measuring liquid level before operation and during trouble shooting only. What methods can be used?
