Inclined tube manometer is simple and cost friendly instrument

which is used to measure the differential pressure. it consists of

two limbs vertical limb acts as a reservoir which generally has

higher volume, and another limb is at inclined angle which is

used for the measurement along the scale. the inclination angle

provides opportunity to operate with the wide range of pressure

the higher angle is preferred for high pressure range and similar

with low pressure range. pressure measurement.
