At left, equal pressure is imposed on the fluid in the well and inthe indicating tube. Reading is zero. At the right , a positive pressure has been imposed on the liquid in the well causing the level to go down very slightly. Liquid level in indicating tube has risen substantially. Reading is taken directly from scale at liquid

The conventional mcleod guage has been modified and range 0.001-10mm H.G. resulting as an accuracy of + 5% at scale point.

Working Principle :
Apart from glass tube level gauges, transparent level gauges are always fitted with two plate transparent glasses between which the fluids is contained. The fluids level is indicated as the result of the different transparency of the two media and in some cases (for water steam) , by conveying upwards on
