Battery Powered Electromagnetic Flowmeter

Battery Powered Electromagnetic Flowmeter

Battery powered electromagnetic flowmeter is a measuring instrument specially designed for the actual requirements of water supply enterprises. It can optimize water supply and use and ensure accurate water trade measurement and settlement. It can be made to remote type, we can make it with pressure test function (this is our patented product).

Fuction：

♦ Full digital signal processing, stable measurement, high measurement accuracy and strong anti-interference capability
♦ Automatic two-way flow measurement, on-site instantaneous flow, positive and negative cumulative total display
♦ Self diagnosis fault alarm
♦ Unlimited remote transmission of GSM, LORA, LORAWAN, NBIOT data

Advantage:

1. Micro power consumption design.
2. The display adopts LCD large screen LCD, which can display instantaneous flow, flow rate (pipe pressure), positive and negative cumulative total amount, alarm prompt and other flow parameters.
3. There are no movable and resistance parts in the measuring pipe, no winding and blocking, almost no pressure loss, and it can work reliably and continuously for a long time.
4. Wide measuring range: the measuring range of flow velocity can reach 0.05m/s~10m/s.
5. High measurement accuracy: ± 0.5%~± 1.0%.
6. Stable measurement: the measurement accuracy is not affected by the change of physical parameters such as temperature, pressure, viscosity and density of the measured medium.
7. It has the function of pulse output, RS485 output, and GSM, LORA, LORAWAN, NBIOT wireless data remote transmission.
8. With data saving function, up to 1000 groups of flow data can be saved, and the interval of data storage time can be arbitrarily set and queried.

Technical parameter:

No.	Electrode material	Corrosion resistance

1	316L	Measuring water, sewage or organic acid or inorganic acid of minor corrosive medium.

2	HB HC	Resistant to corrosion of oxidizing acid such as nitric acid, mixed acid, chromic acid and sulfuric acid, or a mixed medium of corrosion, but also resistant to salts of the oxidation as Fe + + +, Cu + +, or the other oxidant-containing corrosion. Such as hypochlorous acid alkaline solution is higher than normal temperature or sea water corrosion




3	Ti	Applicable in seawater, various chloride and hypochlorite, chlorinated acids (including fuming nitric acid), organic acid, alkali, etc. Do not resistant to the pure reduction acid (such as sulfuric acid, hydrochloric acid) corrosion. However, if an acid containing an oxidizing agent (such as nitric acid and containing Fe + + +, Cu + + ions in the medium) the corrosion is greatly reduced.





4	Tantalum (Ta)	Having strong resistance to corrosive mediums that is similar with glass. Almost applicable in all chemical mediums except for hydrofluoric acid, fuming sulfuric acid and alkali (including the boiling point of hydrochloric acid, nitric acid and sulfuric acid below 175 ℃). It has not any resistant to corrosion in alkali.




5	Stainless steel covered with tungsten carbide	Applicable in mediums of non-corrosive and low abrasion.


6	Platinum-iridium	Almost be applicable in all chemical mediums except for aqua for this, ammonium salt.

No.	Lining Materials	main performance	Applications

1	Chloroprene Rubber (CR)	1.Oil resistance, solvent resistance, oxidation resistance, resistance to general acid, alkali, salt and other corrosive media 2. Excellent flexibility and abrasion resistance. But poor in cold resistance	1.0℃~80℃ Non strong acid, strong alkali, strong oxidizing media 2.can measure sewage and mud




2	Nature Rubber	1. Abrasion resistance, corrosion resistance, insulating properties, good low temperature resistance 2. Poor in oil resistance, aging resistance and oxidation resistance	-10℃~70℃ Non I146 acid, strong alkali, strong oxidizing media,suitable for drinking water





3	Polyurethane rubber	1.Excellent abrasion resistance and flexibility 2.Poor in acid resistance and alkali resistance	1.-25℃~60℃ 2. neutral mash, coal slurry and mud slurry with strong abrasion



4	PFA	1. Good hydrophobic and non-viscous, strong high temperature resistance 2. Excellent corrosion resistance. Resistance to acids, alkalis, organic solvents, and various salt solutions 3. Good ability of negative pressure resistance, also can add metal mesh to improve the ability to negative pressure resistance when requirements is high 4. Poor abrasion resistance	1.-25℃~140℃ non-abrasive media 2. Sanitary media









5	PTFE	1. The most steadiest material in plastics which is resistant to boiling hydrochloric acid, sulfuric acid, nitric acid and aqua regia, as well as strong alkali and organic solvents. Non-resistant to chlorine trifluoride, high velocity liquid fluorine or liquid oxygen, ozone corrosion 2. Poor in abrasion resistance. 3. Not suitable for backward pressure pipeline	1.-25℃~140℃ 2.Strong corrosive media, such as strong acids and alkali 3.Sanitary media









6	FEP(F46)	1. Hydrophobic and non-viscous 2. Corrosion resistance is only lower than PFA 3. Can add metal mesh to improve the ability to negative pressure resistance when requirements is high 4. Poor in abrasion resistance	1.-25℃~100℃ non-abrasive media 2. Sanitary media






7	Nitrile rubber	1. Resistance to high temperature and general acid, heat resistance and abrasion resistance are better than neoprene and natural rubber. Oil resistance is its outstanding properties. 2. Ozone resistance, poor low temperature performance. Lower electricity	1. 0℃~80℃ Ordinary acid, alkali, salt, especially for oily medium 2. Not to be used for low temperature medium
