The small metal Rotameter RAKD differentiates itself from other comparable variable area meters by means of light and guided float design offering the smallest measurable flow ranges in the market. RAKD meters can be fitted with a fine control valve and are designed with horizontal process connections. An integrated flow controller based on the differential pressure principle, which allows a constant flow rate to be maintained regardless of any variations in process pressure, is just one of the many different options available. The RAKD with either standard or fail safe limit switches is suitable for safety applications up to SIL level 2. The configuration with valve and controller reaches SIL level 1. The RAKD Rotameter combines several benefits of the float principle: a robust design, reliable measurements, independence of the electrical power supply when operated as mechanical pointer instruments and an electrical output signal. They are moreover easy to install and require no maintenance. Both the RAMC and the RAKD are packaged in an attractive, all-stainless steel housing and boast a long service life under the harshest industrial conditions.
At first glance, the instrument looks impressive with its all stainless steel design. A closer look reveals a unique patented "float blockage" detection system. Operational safety is of the utmost importance in any flowmeter, and the RAMC is no exception – wetted parts are available in a variety of materials, and intrinsically safe outputs are available as an option. If you value flexibility in a flowmeter – from the measurement of air to highly aggressive liquids – in situ replacement of the indicator without loss of performance – and the interchangeability of floats – then the RAMC is the right choice for you. The RAMC combines all the advantages of the variable area principle with robust design, reliable measurement, with or without power, HART, culminating in a truly universal flowmeter for gases, liquids and steam applications.
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. Coriolis Flow Meter ROTAMASS employs a flame-proof type converter case suitable for use in the hazardous area together with its intrinsically safety type detector. Coriolis Flow Meter ROTAMASS's signal processing, housing protection and its detector's special decoupling system against external loads and vibrations, realize high performance in real applications.
In the last decade, the use of Coriolis flow meters has been changing from general purpose to supporting your needs in specific applications. While the technological complexity increased, the demand for simple operation and handling is also a rising requirement. Yokogawa answers these needs by offering six dedicated product lines with two specialized transmitters allowing the highest flexibility - the ROTAMASS Total Insight.
