Electro Magnetic Flow Meter DN40 For Industrial Process Applications

1. Introduction

A magnetic flow meter is a volumetric flow meter that does not have any moving parts. It is ideal for wastewater applications or any dirty liquid which is conductive or water based. Magnetic flow meters are also ideal for applications where low-pressure drop and low maintenance are required.
Magnetic flow meters will generally not work with hydrocarbons, distilled water, and many non-aqueous solutions.

2.How Does A Magnetic Flow Meter Work?

Magnetic flow meters use a magnetic field to generate and channel liquid flow through a pipe. A voltage signal is created when a conductive liquid flows through the flowmeter’s magnetic field. The faster the flow of the fluid, the greater the voltage signal generated. Electrode sensors located on the flow tube walls pick up the voltage signal and send it to the electronic transmitter, which processes the signal to determine liquid flow.

4. How to select and install a magnetic flow meter?

The key questions which need to be answered before selecting a magnetic flow meter are:

• Is the fluid conductive or water based?
• Is the fluid or slurry abrasive?
• Do you require an integral display or remote display?
• Do you require an analog output?
• What is the minimum and maximum flow rate for the flow meter?
• What is the minimum and maximum process pressure?
• What is the minimum and maximum process temperature?
• Is the fluid chemically compatible with the flow meter wetted parts?
• What is the size of the pipe?
• Is the pipe always full?

6. Maintance

The electromagnetic flowmeter has a self-diagnostic function. In addition to power supply and hardware circuit failures, the system also alarms other failures in general use. These messages will give corresponding prompts in the lower right corner of the screen.

1 Maintenance and repair
a) The sensor installation site should meet the requirements of Section 4, please keep the housing tidy;
b) The transmitter should be placed in a clean, ventilated and dry place;
c) It needs to be inspected every two years. For high-precision users, the instrument needs to be submitted for review.

2 Transportation and storage
a) The instrument must be packaged before transportation, and be handled with care when loading and unloading.
b) The storage place must be dry and ventilated to avoid corrosive gases, and the ambient temperature should not be too low or too high;
c) The storage time should not exceed three years.
