RAMC Variable Area Flow Meter

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 utputs 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® or Profibus PA, culminating in a truly universal flowmeter for gases, liquids and steam applications.

Overview:

With the increased interest in green energy and renewable fuel sources, Biodiesel has emerged as a viable alternative to standard petroleum based diesel and home heating oil. It has zero CO2 emissions and can be created from waste vegetable oil or rendered animal fat. The number of Biodiesel processing plants has grown to over 2500 in the US alone.

Overview:

For nearly 100 years, ozone has been used all over the world for water sanitation. It is nature's strongest oxidizer and has a byproduct of pure oxygen. Chlorine, on the other hand, is a very effective, time-proven chemical, but is ineffective against hard-to-kill microorganisms such as cryptosporidium; it also has some unpleasant byproducts. Ozone is recognized among the strongest, fastest, commercially available disinfectants and oxidants for water treatment, Ozone is used in both the disinfection of drinking water and bacterial killer in waste water treatment. Ozone is used in a large percentage of Municipal water treatment facilities as well as Pharmaceutical companies where pure water is essential.

Overview:

One of the major prohibitive factors for expanding solar power in the market place is the high cost. The primary cost drivers in solar cell marketing are materials and manufacturing processes. Most solar cells in use today use silicon as the semiconductor that enables the photoelectric effect within the solar cell. Silicon is abundant but also expensive and in high demand as the solar and electronics industries compete for global supplies. There is now a cost effective process in use to extract the pure silicon needed for solar cells using less energy and reduced cost. This process is called the Fluidized Bed Reactor.

Product Overviews

    Product Overview
    Overview:

    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.In the 1990s, Yokogawa strengthened its focus on flowmeters through cooperation with and the eventual acquisition of the German flowmeter manufacturer ROTA. In so doing Yokogawa gained access to 100 years of flowmeter expertise and completed its flowmeter portfolio by adding the Rotameter (variable area) and Rotamass (Coriolis) product lines.
