What media can be measured by Cheap electromagnetic flowmeter materials ?
1. Cheap electromagnetic flowmeter material has no mechanical inertia and sensitive response. It can measure the instantaneous pulsating flow and the flow in both positive and negative directions. The diameter range of industrial electromagnetic flowmeter is very wide, from a few millimeters to a few meters, and there are real flow calibration equipment with a diameter of 3m in China, which has laid a foundation for the application and development of electromagnetic flowmeter.
2. The sensor of cheap electromagnetic flowmeter material has simple structure, and there are no movable parts in the measuring pipe, nor any throttling parts that hinder fluid flow. Therefore, when the fluid passes through the flow meter, it will not cause any additional pressure loss. It is one of the flow meters with low energy consumption. It can measure the flow of dirty medium, corrosive medium and suspended liquid-solid two-phase flow. This is because there are no flow blocking parts inside the instrument measuring tube, and only the measuring tube lining and electrode are in contact with the measured fluid
The cheap electromagnetic flowmeter material can be selected according to the properties of the measured fluid. For example, with polytrifluoroethylene or polytetrafluoroethylene as the lining, various corrosive media such as acid, alkali and salt can be measured; Using wear-resistant rubber as lining is especially suitable for measuring liquid-solid two-phase flow such as ore pulp and cement pulp with solid particles and various suspended liquids such as fiber liquid and pulp.
Cheap electromagnetic flowmeter material can only be used to measure some conductive liquid or slurry, not gas. It is mainly determined by the inherent characteristics of electromagnetic flowmeter. Let's analyze the reasons in detail below.
The cheap electromagnetic flowmeter material is mainly insufficient: it can not be used to measure gas, steam and liquid containing a large amount of gas. It cannot be used to measure liquid media with low conductivity, such as petroleum products or organic solvents. At present, good price and quality electromagnetic flowmeter material is powerless.
