 PCL Series Integrated Electromagnetic Flowmeter

Integrated/Divided/Battery Electromagnetic Flow meter

Introduction

PCL series electromagnetic flowmeters, composed of sensor and converter, work based on Faraday’s law of electromagnetic induction. It is used to measure electrical conductivity of liquid or solid. Generally, the electrical conductivity should be over 5uS/cm (electrical conductivity of tap water, raw water is about 100-500uS/cm. It can also be used to measure various mediums like acid, alkali, saline solution, paper pulp, ore pulp and so on, but these mediums cannot contain a lot of magnetic materials and bubbles.

 

Working principle

The principle of the sensor is based on Faraday’s law of electromagnetic induction. It is installed a pair of detection electrodes on the pipe wall, where the measurement pipe axis and magnetic field lines are vertical. When the conductive liquid moves along the measurement pipe axis, the conductive liquid cuts magnetic field lines and produces induced electromotive force, which can be measured by the two electrodes on the meter pipe. The result can be calculated by the formula:

When measuring flow, fluid flows through magnetic field which is perpendicular to the direction of the flow. Then the flow of conductive fluid induces electromotive force proportional to the average velocity. Therefore, the detected fluid requires to be higher than the minimum of electrical conductivity. Its induced voltage signal is detected through two electrodes and sent to a converter through the cable. After signal processing and related operations, PCL electromagnetic flowmeter will display total flow and instantaneous flow in converter display.

Material Selection

 

Lining material selection

 

Lining material should be chosen according to the erosion, abrasion and temperature of measuring medium. The applicability of common lining materials are as follows.

Electrode material selection

 

Electrode material should be selected according to the corrosion resistance of the measuring medium.

Ground ring selection

 

The inductive signal voltage of electromagnetic flowmeter is low, so it is easy to be affected by outside noise or other electromagnetic signals. The function of ground ring is to form a space to shield outside interference so as to increase the accuracy by grounding the body of flowmeter. (The ground ring is required when you use non-metal pipe.) Installation methods in different conditions are as follows.
