The flow hydrant is fitted with a diffuser device containing a pitot tube that measures stagnation pressure in the middle of the stream while the hydrant is ...

The history of testing, inspection and certification services spans back several centuries. In the late 19th century, following the advent of the Industrial Revolution and the considerable risks involved with high-pressure steam boilers, specialized institutions emerged across Europe which carried out periodical inspections of such vessels to assess their overall condition as a precautionary ...
