Magnetic Water Flow Meter Battery Powered Operated Electromagnetic
Description Magnetic Water Flow Meter Battery Powered Operated Electromagnetic
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
3 Sea water, alkali solution, the oxide solution has excellent
corrosion resistance 4 NA: hydrochloric acid |
| Hastelloy B | HB | 1 for the non-oxidizing acids, bases, salts such as sulfuric acid,
phosphoric acid, hydrofluoric acid has good corrosion
2 NA: nitrate |
|
| 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 |
