Rotameter Flow Meters

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.

    Custom Applications

  • Thie Mini Rotameter RAGK is designed for measurement of liquids and gases. The conical glass metering tube has a free rotating float. Measureable Flow Rate: Water = 0.002 l/h to 600 l/h; Air = 0.2 l/h to 6300 l/h

  • The Rotameters RAGK/ RAGL are specifically designed for the measurement of low flows of liquid and gases. Their main application field is in purging, analyzer and gas sampling systems, laboratories and machinery equipment.

Rotameter HistoryIn 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.

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:

One of the most widely used methods of monitoring / controlling liquid level in a tank is the use of Bubble Tubes with Pressure or Differential Pressure Transmitters. A small but uninterrupted flow of air or inert gas is forced down through a dip tube which extends to near the bottom of the tank. The back pressure of the introduced gas is a function of the liquid level or head in the tank. The pressure transmitter takes the back pressure and converts it to an analog signal that is sent to the control room. The plant operator will then be able to monitor the exact level in the tank.

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.

Industries:
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.
