Hydrogen is the simplest and smallest atomic element. Water, acids, bases, and the immense family of organic compounds all contain hydrogen. Even though hydrogen is not corrosive, it can cause problems for pressure transmitters through Hydrogen Permeation.
Differential pressure transmitters, which serve as the core of field instrumentation, are widely used to measure the flow rate, pressure and density of liquids, gases and steam, as well as the level of liquid in a tank.

Yokogawa's new facility in Singapore will play vital role in its regional and international growth. Yokogawa Electric Corporation, a leading company in industrial automation (IA) and technology solutions, recently announced the completion of its 12-storey building in Singapore. The new facility will play a crucial role in Yokogawa's vision to be the top global IA player by 2010.
Differential pressure level measurement has an enemy- temperature. Temperature can have a negative effect on the accuracy of level measurement. This article covers why temperature has this effect and how it can be reduced.
