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.

  • ROTAMASS is the integral and remote type Coriolis Mass Flow Meter. Both types have highly refined digital signal processing electronics, so that accurate and stable mass flow measurement is achieved.

  • Magnetic flow meters are ideal for conductive fluids in chemical, slurry, and mining applications, with minimal pressure loss. Available in four and two-wires.

  • Yokogawa's vortex flow meters are long-lasting and robust, offering field-proven sensor technology and high reliability to deliver improvements in plant efficiency and reduce OPEX.

  • Variable area flow meters, or rotameters, are some of the oldest devices used for flow measurement, known for their flexibility across various applications and high reliability.

  • Differential pressure (DP) flow measurement is a well-known and common technology for measuring flow in a closed pipe.

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

The standard accuracy for the output of an AXF is 0.35% of Rate/Reading. Yokogawa also offers a high grade accuracy calibration option which provides an accuracy of 0.2%.
Sizes 2.5 to 10 mm (0.1 to 0.4 in): 5 µS/cm or greater Sizes 15 to 125 mm (0.5 to 5 in): 1 µS/cm or greater Sizes 150 to 400 mm (6 to 16 in): 3 µS/cm or greater When conductivity is below the 3 µS/cm, we recommend using ...
Yokogawa Technical Report
Overview:

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
Overview:

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.
