Introduction

Electromagnetic Flowmeter is a speed instrument for measuring the volume flow of conductive medium. It can output standard current signals for recording, adjustment and control while monitoring and displaying on the spot, so as to realize automatic control of detection and remote transmission of signals. It can be widely used in the flow measurement of conductive liquid in tap water, chemical industry, coal, environmental protection, textile, metallurgy, paper making and other industries.

The main advantages of using electromagnetic flow meter is that it is with no moving parts, no pressure loss and require very less maintenance.
Flange type magnetic flow meter can be made large size range from DN3-DN3000mm and with bi-directional flow measurement. Aister's electromagnetic flow meters are with built-in self-diagnosis function and support data record / bluetooth function and various kinds of output signals.

Compared with other liquid type flow meter, the limitations of magnetic flow meter is that it can only be used for conductive liquid.Regarding non or low conductive liquid such as petroleum products, organic solvents can not be used. Electromagnetic flow meter will be affected if there's strong magnetic filed in the surrounding environment.

Installation

In order to obtain a stable and accurate flow measurement, it is very important that the flow meter is installed correctly in the pipe system.
Do not install the meter near equipment that produces electrical interference such as electric motors, transformers, variable frequency, power cables etc.
Avoid locations with pipe vibrations for example pumps.
Do not install the meter close to pipeline valves, fittings or impediments which can cause flow disturbances.
Place the meter where there is enough access for installation and maintenance tasks.

lnstall at the lowest point and vertical upward direction Don't install at the highest point or vertical downward diection	When drop is more than 5m, install exhaust valve at the downstream
lnstall at the lowest point when used in open drain pipe	Need 10D of upstream and 5D of downstream
Dont' install it at the entrance of pump, install it at the exit of pump	lnstall at the rising direction
