Why we use different manometric fluid in manometer rather than pressure measured fluid?
Why can't we just use the same fluid that we are measuring the pressure of?
One reason is that the fluid being measured may not be suitable for use as a manometric fluid due to factors such as viscosity, reactivity with the material of the measuring device, or inability to maintain a stable, measurable meniscus. Additionally, using a fluid with a different specific gravity can allow for a greater range of measurement sensitivity, which is important for accuracy.
