If you want to choose a suitable chemical flow meter, you must first understand the characteristics of the chemical raw materials you need to measure. According to different forms, chemical raw materials can be divided into solid chemical raw materials, liquid chemical raw materials, and gas chemical raw materials. There are many liquid and gas chemical raw materials, and most of them are corrosive. Special attention should be paid to them during transportation and storage. The chemical flow meter mainly measures gas and liquid chemical raw materials. Common characteristics of chemical fluids that need to be considered when measuring flow rate: Corrosive This is the most common characteristic of chemical materials. Corrosive acid, alkali, salt solution. Flammable and explosive Compared with flammable liquids and solids, flammable gas is easier to burn, and the burning speed is fast, and it burns out. Gas composed of simple components is more flammable, the faster-burning rate has higher flame temperature and greater risk of fire and explosion than gas composed of complex components. Electrified Most flammable liquids are electrolytes. Such as crisps, ketones, gasoline, esters, aromatics, and petroleum products. These substances are transported, poured, shaken, stirred, and flowed at high speeds in pipelines, storage tanks, tank trucks, and oil tankers. Because friction is easy to generate static electricity, when the static charge accumulated to a certain extent, static sparks will be generated, which may cause burning and explosion. Stickiness Such fluids include glue, resin, asphalt, and molasses.
