INTRODUCTION Water, which is in abundance on planet Earth is the primary and most important sustenance of life on it, as it is an essential resource in human activities including human production and industrial works. As human society developed and got more complex—especially with the radical improvements in technology—problems such as low availability of water

The economic factors considered in the application of electromagnetic flowmeters should generally include instrument purchase costs, installation costs, maintenance cycles, and flow calibration costs. When applied to trade accounting, the losses caused by measurement errors should be compared. 1. Electromagnetic Meter purchase costs The price of electromagnetic flowmeters can be roughly divided into two categories.

These top 10 electromagnetic flowmeter manufacturers in the world have changed and affected the growth of technology, all from building electromagnetic flowmeters to influencing several industries in the world today. These manufacturers offer a wide range of differential pressure flowmeters, variable area flowmeters, and electromagnetic flowmeters. They are the leading supplier of flow meters and

These top 10 electromagnetic flowmeter manufacturers in China have changed and affected the growth of technology, all from building electromagnetic flowmeters to influencing several industries in the world today. Regardless of the year, these companies were established, they have made a great impact in the world market and are worth millions of dollars. Here are

After initial debugging and normal operation for a period of time, the common causes of failures during operation are adhesion layer on the inner wall of the flow sensor; lightning strikes; changes in environmental conditions. 1. The inner wall adhesion layer Because electromagnetic flowmeters have more chances to measure suspended solids or dirt bodies than

This type of fault appears during the initial installation and commissioning of the electromagnetic flowmeter, but once the fault is improved and eliminated, it will generally not reappear under the same conditions in the future. Common failures during the commissioning period mainly include three reasons: improper installation, environmental interference, and fluid characteristics. The piping system

Conductive fluids Metals are famously conductive materials for heat and electricity due to the presence of free electrons and ions. Similarly, some fluids are also conductive and possess free ions and electrons due to which it conducts electricity. This property of a fluid is referred to as conductivity which is measured in micro Siemens (µS).

When transporting and hoisting the sensor, the sling should be put on the neck position or the hoisting ring at both ends of the sensor. Do not put a pipe rod in the measuring tube for hoisting, so as not to damage the lining (see Figure 6-27). During hoisting and transportation, the sensor lining and

The electromagnetic flow sensor lining made of polytetrafluoroethylene (PTFE) pipe is generally not glued to the wall of the sensor measuring tube, so it is sensitive to vacuum negative pressure. The vacuum in the pipeline will deflate the PTFE lining, making the lining arched in a wave-like shape—a typical negative pressure damage pattern. This destroys
