Flow Meters

Flow meters are used to measure the volumetric or mass flow rate of a liquid or gas. Yokogawa's range of flow meter instruments include vortex, magnetic, variable area, Coriolis, and differential pressure flow meters.

The Coriolis flow meter has many features such as direct measurement of mass flow and measurement of fluid density, which other flow meters do not support. Therefore, since being introduced for practical use in the late 1970s, its market has rapidly expanded in many industries such as oil, chemicals, and foods.

Yokogawa Technical Report

Vortex flow meters were put into practical use in the 1970's; thus their history is relatively short. They have been mainly used at petrochemical plants because of their two main features, the fact that they do not have any mechanical moving parts and are maintenance-free. Yokogawa started research and development on the vortex flow meter before 1970.


Thanks to a two year upgrade project, Foster's Yatala brewery is now one of the country's most efficient integrated brewing and packaging operations. More than 1,100 measurement and control devices from instrument manufacturer Yokogawa Australia will help keep it that way.

Sizes 25 to 200 mm (1 to 8 in): 10 µS/cm or greater.
Sizes 1000 mm (40") and below: 20 µS/cm or greater Sizes 1100 mm (44") and above: 50 µS/cm or greater 
Sizes 15 to 100 mm (0.5" to 4"): 0.01 µS/cm or greater Sizes 150 & 200 mm (6" & 8"): 1 µS/cm or greater
