Mag-11 Series Thread 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).

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.
| Material | Performance of Corrosion Resistance | WorkingTemperature | Applicable Range | Diameter(mm) |
| PTFE | Almost have the corrosion resistance to all chemical media. | -40 ~150℃ | All media besides the fluid in negative-pressure pipe and also the fluid has the good wear resistance. | DN15-1200 |
