Wireless Remote Battery Powered Digital Water Flow Meter
Description Wireless Remote Battery Powered Digital Water Flow Meter
803E series electromagnetic water meter converters are battery powered, capable of being used together with common electromagnetic flow meters, with the flow rate measurement accuracy up to 0.5 level and 0.2 level. That is to say, a new type of products — electromagnetic water meter series will be developed simply by connecting a 803E convertor to a common electromagnetic flow meter.
The 803E electromagnetic water meter converter is equipped with a lithium battery as its standard configuration, which can work over three consecutive years. If a high-capacity battery is equipped, the continuous working time will be much longer.
Designed with IP68-level seal protection for its die-cast aluminum case, the 803E electromagnetic water meter converter is particularly applicable for damp environment, for example, underground mine.

Select the lining material
Should be based on the measured medium temperature corrosive wear and to select the lining material
| Lining material | corrosion resistance | Working temperature | Application |
| Ne | General resistance to low concentrations of acid salt corrosion | -20～70℃ | lower industrial water effluent pH and salt concentration |
| PO | Has an excellent wear resistance, abrasion resistance slurry dedicated to strong, not decay | -10～60℃ | Liquids containing solid particles (slurry pulp, etc.) |
| FEP | 1 corrosion resistant and quite PTFE 2 high mechanical strength, good wear resistance 3 table smooth, easy adhesion precipitate 4 have strong abrasive media fluid good resistance to outside negative, anti-vacuum effect | -40～180℃ | except mortar. Like with PTFE can be used for drinks and other health requirements of the media |
| PTFE | lmost all of the corrosion resistant chemical media, poor wear resistance | -40～180℃ | Not be used for pipes and wear strong negative fluid |
Selective Electrode Materials
Should be based on the measured fluid corrosive to select material of the electrodes, check the manual for special fluids should be corrosion test
| Material | Code | corrosion resistance | |
| 316Lstainless steel | V | 1 applies to a neutral solution of industrial, domestic water, raw water wells, urban sewage 2 weak corrosive acids, bases, salts medium such as carbonic acid, acetic acid, etc. | |
| Hastelloy C | HC | 1 applies to anti-oxidizing acids, such as a mixture of nitric acid, mixed acid, chromic acid and sulfuric acid 2 oxidation resistance salt or other corrosive environments, such as the oxidant Fe, Cu 4 NA: hydrochloric acid | |
| Hastelloy B | HB |
| |
| Titanium | Ti | seawater resistant, various chlorides suddenly hypochlorite and a variety of corrosion hydroxide | |
| Ta | Ta | except hydrofluoric acid, almost all corrosive chemical media capability. But expensive | |
| Platinum | Pt | salt solution applicable to all of the acid (fuming sulfuric acid and nitric acid) | |
| Tungsten | W | has excellent wear resistance, dedicated to the mud, pulp and other abrasive media |
