Original Yokogawa ROTAMETER RAMC Variable Area Flowmeter RAMC01

Original Yokogawa ROTAMETER RAMC Variable Area Flowmeter RAMC01

The RAMC variable area flow meter (rotameter) by Yokogawa is a truly universal flow meter, ideal for measuring air and highly aggressive liquids in low and high-temperature applications. The RAMC features a float blockage detection system, all mechanical design, and easily replaceable components, making it easy to maintain while delivering high reliability and performance.

Yokogawa’s variable area flow meters adhere to the highest operational safety standards, and the RAMC is no exception with wetted parts available in a variety of materials and optional intrinsically safe outputs.

The RAMC combines all the advantages of the variable area principle with robust design and reliable measurement. A truly universal flowmeter for gases, liquids, and steam applications.

All Mechanical Design
The RAMC has a simple, robust design with three common components, making it ideal for low and high temperature applications, as well as making it highly reliable and reducing maintenance costs.

Field Replaceable Components
Many components of the RAMC are replaceable, including the float, scale, eprom (for eletronic transmitters), limit switches, and housing.

Float Damping System (for Gas Applications)
The float damping system is used in gas applications to avoid bouncing and putting a lot of wear on the float itself. The system is retrofittable and exchangeable at any time without requiring the operator to replace the float, and it can withstand a pressure maximum of up to 40 bar absolute. With this damping system, no recalibration is necessary after installation of the damping, and it is available to add on to old Yokogawa rotameters.

Float Blockage Indication System
This function is used for the electronic transmitter and detects when fluctuations remain under the preset level, activating an alarm.
