Digital Output Oil Gas Water Electromagnetic Flowmeter Battery Flow Meter
Product Description
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.
(Data table for reference only)
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 should be selected according to the corrosion resistance of the measuring medium.
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.

| Electrode material selection |
Electrode material should be selected according to the corrosion resistance of the measuring medium.
| Electrode Material | Main Properties |
| 316L | Measure the medium such as water, sewage or inorganic acid, organic acid with slight corrosion. |
| HC | Resist the corrosion of oxidizing acid, such as nitric acid and mixed medium of chromic acid and sulfuric acid, and oxidative hydrochloric acid, such as Fe+++, Cu++ and some other oxidants, such as sub-argon salt solution higher than normal temperature and oily water. |
| Ti | Resist the corrosion of salt water, various oxides, hypochlorite, oxidizing acid (including fuming sulfuric acid, nitric acid), organic acid, alkali and so on. It is not resistant to the corrosion of pure reductive acids such as sulfuric acid and hydrochloric acid, but if oxidizing agents are contained in acid, the corrosion is greatly reduced. |
| Ta | Have good corrosion resistance similar to glass. Resist the corrosion of almost all chemical medium, except hydrofluoric acid, fuming sulfuric acid and alkali. Sodium hydroxide and other alkaline solutions are not applicable. |
| Pt-Ir | Have good corrosion resistance of all acid, and can resist the corrosion of alkali and all salt. |
