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.
Yokogawa's experience with magnetic flowmeters spans decades. Our magnetic flow meters provide flexible configurations for industrial use in most areas.
Yokogawa has been synonymous with Vortex flowmeters since pioneering the industrial Vortex flowmeters from 1969. Even since then, Yokogawa has continued to be at the fore front of vortex technology; so, today, Yokogawa offers a large variety of Vortex flowmeters, including custom made designs.
The Variable Area Flowmeter is one of the oldest and mature principles in flow measurement with its simple design: a float rises inside a conically shaped glass tube as the flow increases and its position on a scale can be read off as the flow rate. Since this measuring method is purely mechanic, it as simple as it is reliable.
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.
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.
