Electro Magnetic Flow Meters

Electromagnetic flow meter provides accurate volumetric flow measurement for liquid in closed pipe. Electromagnetic flow meter is often called as: magnetic flow meter,mag flow meter,mag meter,mag-meter,electromagnetic water flow meter,etc. No matter what is called, magnetic flow meter is a kind of high accuracy flow device.Magnetic flow meter has been proved its strength in liquid  flow measurement and widely used in the world.

Magnetic flow meter is developed on Faraday law of electromagnetic induction, and the fluid induction should be bigger than 5um/s. Thus,if the liquid has a low induction,magnetic flow meter won't be able to measure.Even thought it can test, the performance may not be well all the time.

Advanced mag meter can provide accurate flow measurement for liquid,e.g.water,etc.It has no moving parts,so it has no pressure loss.With leading cutting-edge technology,the magnetic meter features high accuracy,reliable performance,long-life,wide flow range,etc.Based on high cost-effective solution and good performance, our magnetic flow meters have been widely used for water,sewage water,sea water, living water,acid,alkali,salt,slurry, irrigation,etc.

In order to meet different requirement,we supply different types of magnetic flow meters and mainly includes inline & insertion type, separated &integrated type,battery powered&external power type,sanitary type,etc.Meanwhile, we can also supply converter of mag meters for customers to make their own brand mag flow.

Inline Full Bore Electromagnetic Flow Meter

Inline type flow meter is the main selling type of magnetic flow meters. It has separated type and integrated type. Separated type refers flow converter and flow sensor are not welded together and connected by special cable. User can select related relation as actual requirement.
For connection way of inline mag meter, there are mainly 3 kinds: standard flange, thread connection for small size and plug-clamp type.

Insertion Magnetic Flow Meter

Insertion magnetic flow meters can be used for bigger size pipe with lower cost.If users don't want to cut pipe fully or want to flow stop for more hours, insertion flow meter is a better choice.
The insertion magnetic flow sensor is wholly molded with steel material and can be used for long term in harsh environment.

• Power supply:AC110-240V;DC24V;Solar Power

Battery Powered Magnetic Water Meter

The battery powered magnetic water flow meters for pipe size below DN350mm. The mag meter has RS485 port supports Modbus protocol. Our battery powered magnetic flow converter can be separately.If you want to make battery powered mag-meter, please feel free to contact.

Main Specification

• Pipe size:DN8-DN2000mm
• Accuracy:+/-0.5%(F.S.)(>0.3m/s)
• Fluid temperature range:-10 to 80.C..Higher temperature optional.
• Working temperature:-25 to 60.C.
• Relative humidity: 5%-95%(RH)
• RS485(Modbus)
• Conductivity:>20us/cm
• Protection class: Sensor：IP65，IP68. Converter:IP65
• Power supply:3.6V built-in battery,over 5 years life;Solar Power

Except magnetic water meters, you may consider using battery powered ultrasonic water meter. It has a higher cost-effective solution.Meanwhile, ultrasonic water meter has a greater promising than magnetic meter.

Battery Powered Magnetic Flow Electronic Converter

We can provide battery powered magnetic flow converter separately for your magnetic flow sensor. Without battery flow converter,you can make your own magnetic water meters.

Following industrial class standard,the magnetic converter can  meet the trade requirement of water supply and distribution and have been widely used for application without external power,e.g. city water supply,sewage process, irrigation works,etc.

Main Specification

• Pipe size:DN10-DN1000mm
• Accuracy:+/-1%(F.S.)(>0.3m/s) (Decided by configuration sensor)
• Working temperature:-20 to 50.C.
• Relative humidity: 5%-95%(RH)
• RS485(Modbus)
• Pressure range:0.6-4.0MPa
• Protection class: IP65，IP68
• Power supply:3.6V built-in battery,3-65 years life; External 12Vdc
• Pulse output for volume flow rate
• 4-20ma(2-wire).Optional
• Signal input: pressure,temperature
• Flow velocity:0.01m-15m/s

We also have electromagnetic heat flow meter for energy monitor and management. By equipped with PT100 resistor, our magnetic flow meter can measure temperature difference of water flow,and then calculate energy consumption.

4 Important Parts of Mag-Flow That You Should Know

a.Flow Converter

Mag flow converter is in charge of calculating. As power supply way, it has battery power,DC power and AC power. As display screen, it has standard display version and 4-20mA transmitter version without local LCD screen. As technology,common version and special type are available. Flow converter is the most important part of magnetic flow meter.

b.Flow Sensor:Inline and Insertion Type

Magnetic flowmeters mainly have two kinds of flow sensors:inline type and insertion type. Inline type is pipe section style which is the main selling. Insertion type is rod type and mainly used for bigger size pipe. Inline type has higher accuracy than insertion type.

C.Electrode Material

Often used electrode materials mainly includes 316L stainless steel,Hastelloy(HC), Titanium(Ta),Tantalum(Ta),etc. 316L is the most often used electrode material.

d.Lining Material

There are 4 kinds of often used lining material:rubber(Neoprene,Polyurethane),PTFE,F46,etc.
