A common instrument used to measure pressure in multiple devices and liquids.
A Manometer is that of a U shaped instrument that measures the pressure of liquids and gases in different devices. Generally, a simple manometer will comprise a U shaped glass vessel that has liquid mercury fillings open at both ends. The mercury indicates the change of temperature. Once, the height of the fluid rises, showing a rise of the pressure and vice versa. Today, we have two kinds of Manometer namely the digital and the analog. For more effortless accurate readings, choose a digital while for simple causes an analog one can serve the purpose quite well.
