Totalizers, also referred to as total flow meters, typically measure the total flow volume within a closed pipe system. Today, many types of totalizers have several functions. Some may measure additional information, such as flow rate. While some totalizers operate mechanically, others use electrical power. Differences in type, design and material all affect the suitability of a totalizer for a particular function. When selecting a total flow meter, users typically want great function and cost-effectiveness. These attributes are not one-size-fits-all either, as they can be affected by the working environment, the substance being measured and the purpose of the meter. This article will provide a break down of the different types of totalizers in order to help you choose the best totalizer to suit your needs.
A batch controller calculates the number of items or the volume of things that are being processed at any given time. If these are solid objects, they work in the form of counters to calculate individual things, but when it comes to gas or liquid, these batches need to be counted by other means. Liquids and gasses pass through tubes when they are transferred and the volume of material must be communicated in the form of velocity, such as through rate per minute.
