Mag-11 Series Flange Connection Electromagnetic Flowmeter is the flow meter with the function of cold,heat measurement,usually called electromagnetic energy meter or electromagnetic heat meter. It is applied in heat exchange loop, measuring the energy which is absorbed or converted by the heat carrier liquid. Energy meter displays the heat with the legal unit of measurement(kWh), not only measuring the heating capacity of heating system,but also measuring the heat absorption capacity of cooling system.
Mag-11 Series Electromagnetic Flow meter consists of flow measurement unit(flow sensor), energy calculation unit (converter) and two precise paired temperature sensors(PT1000).

Note: “ O” in the sheet means that different types of flow meters can choose different lining material.
When the working pressure of measured pipe is higher than pressure of sensor, the flow meter can be customized from our company.
The connection size in the sheet is designed according to GB/T9119-2010 standard,if you want the other connection size(such as ANSI/JIS ), can be customized from our company.

Lining Material Selection
1. For high-temperature media (≥140℃),preference for PFA lining
2. For the media with sanitation requirement should select FEP(or PTFE) lining
3. For the wearing media such as slurry and pulp should select PU or FEP lining.
4. For easy scaling media such as paper pulp, preference for FEP or PFA lining.
5. In the case of negative-pressure, should select FEP.

Temperature |
Applicable Range | Diameter

| PU | Have good wear resistance,used for the wearing slurry, but with poor corrosion resistance. | -30~80℃ | Liquid containing solid grains(grout, slurry) | DN15-400 |
| FEP | The corrosion resistance is equal to PTFE. | -40 ~150℃ | All fluid besides the wearing media such as mortar. | DN3-400 |
