Description



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.   RAKD General Specifications  RAKD User's Manual Terms of Use for ManualsList of Rotameter General SpecificationsList of Rotameter User's Manual
