24VDC 4-20ma two wire system magnetic flowmeter
Introduction and Application
Intelligent electromagnetic flow meter is hallmarked by its high performance and reliability based on successful, field-proven technology. It is being widely used in industries such as petroleum, chemical engineering, iron and steel, food, electricpower, paper making, water treatment, petrochemical, medicine etc.
Features
- Measurement depends on fluid density, humidity, temperature, pressure and conductivity.
- There is no obstructive in the conduit and no pressure drop, and the straight pipe required is relatively short.
- The sensor is equipped with the advanced processing technology that provides excellent immunity to negative pressure.
- LCD display of the converter makes it easy to read during daylight and in darkness.
- Parameters can be set up using infrared touch nubs no need to open the cover of the converter.
- Automatic alarm functions for selfdiagnosis, empty load test, high and low limit of flow, two-stage flow value, etc.
- It is applicable not only to general process, but also in tough applications such as mining, papermaking, pastry, etc.
- High pressure sensor with PFA liner is resistant to high pressure and negative pressure, and available to chemistry and corrosive solution.

Main performances of the electrode materials
| Electrode material | Applications |
|---|---|
| sainless steel SUS316 | Applicable in water,sewage and corrosive mediums. |
| Widely used in industries of petrol,chemistry,carbamide,etc | |
Stainless steel covered with tungsten carbide | Applicable in mediums of no corrosive and low abrasion. |
| Hastelloy B(HB) | Having strong resistance to hydrochloric acid of any consistance which is below bioling piont. |
| Also resistable against vitriol,phosphate, | |
| hydrofluoricacid,organic acid etc which are oxidable acid,alkali and non-oxidable salt. | |
| Hastelloy C(HC) | Be resistant to oxidable acid such as nitric acid,mixed acid |
| as well as oxidable salt such as Fe+++,Cu++aStnd sea water | |
| Titanium | Applicable in seawater,and kinds of chloride,hypochlorite salt,oxidable |
Not resistant to a pure reducing acid(such as sulphuric acid,hydrochloric | |
| But if acid contains antioxidant is greatly reduce corrosion. | |
| Tantalum | Having strong resistance to corrosive mediums that is similar with glass |
| Almost is applicable to all chemical mediums. | |
| Except for hydrofluoric acid,oleum and alkali. | |
| Platinum-iridium | Almost be applicable in all chemical mediums except for ammonium salt. |
