For those occasions when rotameters do not fit the application, Orange Research may have a solution. Orange Research variable-area flow meters have large, bright, easy-to-read dials. They can be a refreshing alternative to rotameters that have become coated with the dirt and particulate from the process fluid, making it difficult to see the float. In addition, many rotameters have smaller markings that sometimes take eyeglasses to read, like some thermometers. Under bright lights rotameters often have reflections that compound the readability issue. Being round, they can concentrate light directly at the user’s eyes, often from many angles.
Even if you can see the float in the rotameter tube there’s the question of what part of the float you take the reading from: the top, the bottom, or is there some line on the float that the user should be looking for? Orange Research meters have a bold black tapered pointer, similar to those found on pressure gauges, that easily directs the user to the proper reading, with no questions.
