Introduction Features Specifications Model Selection Application Installation

Introduction

Electromagnetic flow meter is widely used in water treatment, food industry, pharmaceutical, petrochemical, paper mill, chemical monitoring etc.
In the metallurgical industry, it is often used to control the flow of cooling water for continuous steel casting, continuous steel rolling, and steel-making electric furnaces;
In the field of water supply and drainage in public utilities, electromagnetic flow meters are often used for the transfer measurement of finished product water and raw water in water plants;
In the pulp process of the paper industry, electromagnetic flow meters are involved in the measurement of the flow of grinding pulp, water, acid, and alkali;
In the coal industry, measuring coal washing and pipeline hydraulic conveying coal slurry.
For food and beverage industries, it is used for beer and beverage filling measurement.
For chemical and petrochemical industries, it is used to measure corrosive liquids, such as acids and alkalis etc.

Features

1.Wafer electromagnetic flow meter has short body, it can be installed in narrow areas such as well, ditch, irrigation pipe, etc.

2.It matches all flanges like ANSI, DIN, JIS, etc. So if you don’t know the flange standards, you can choose this type.

3.And wafer electromagnetic flow meter adopts harmless and durable stainless steel as raw material(SS304 or SS316), so it can be used for drinking water, underground water, etc. For food grade measurement, we suggest customer use SS316 material.

4.Wafer Electromagnetic flow meter is also very cheap, normally it is cheaper 10% than same diameter electromagnetic flow meter with flange connection.

5.Wafer electromagnetic flow meter is easy to delivery, save your freight fee. Not only its body is short and thin, but its weight is also very light.

6.It has multiple output signals for choose. It has current output and pulse output for connecting with PLC or other devices. And you can also read flow measurement by RS485/HART/Profibus

Installation

1. Installation
First of all, we need choose a pair of matching flanges. Then connect the flow meter with pipeline.
Wafer electromagnetic flow meter should be installed correctly to ensure good measurement. Normally we need leave 10D(10 times of diameter) straight pipe distance before wafer electromagnetic flow meter and 5D behind wafer electromagnetic flow meter.
And try to avoid elbow/valve/pump or other device which will influent the flow speed. If the distance is not enough, then please install flow meter according to follow picture.

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

2. Maintenance
Routine maintenance: only need to make periodic visual inspections of the instrument, check the environment around the instrument, remove dust and dirt, ensure that no water and other substances enter, check whether the wiring is in good condition, and check whether there are newly installed strong electromagnetic field equipment or newly installed wires near the instrument Cross-instrument. If the measuring medium easily contaminates the electrode or deposits in the measuring tube wall, it should be cleaned and cleaned regularly.
