Scales are used to measure weight. Flow meters are used to measure the rate of flow of a liquid or gas. But in some situations, it is possible to utilize a high quality industrial scale to perform both functions. Sometimes this may be done for the purpose of saving the cost of the flow meter. In other cases, because of the type of liquid or the nature of the application, it is not practical to use one. A small container of liquid or liquefied gas may be weighed on a bench scale or cylinder scale. Larger tanks will be weighed on platform scales, drum scales or floor scales. In all of these cases, a highly accurate industrial scale can detect very small changes in the weight of liquid in [+]
