1、 Product principle of lithium battery electromagnetic flowmeter

The Platinum Ray LDE lithium battery electromagnetic flowmeter is based on Faraday's law of electromagnetic induction and is used to measure the volumetric flow rate of conductive liquids with a conductivity greater than 5 μ S/cm. It is an inductive instrument for measuring the volumetric flow rate of conductive media. In addition to measuring the volumetric flow rate of general conductive liquids, it can also be used to measure the volumetric flow rate of strongly corrosive liquids such as strong acids and alkalis, as well as homogeneous liquid-solid two-phase suspensions such as mud, slurry, and pulp, as shown in Figure 1.

2、 Performance characteristics of lithium battery electromagnetic flowmeter

1. Micro power design, 3.6V lithium battery, capable of continuous operation for 5 years, and easy battery replacement.

2. The monitor adopts an LCD large screen LCD display, which can display multiple flow parameters such as instantaneous flow rate, flow rate (pipeline pressure), cumulative total amount in both directions, and alarm prompts.

3. There are no movable or resistance components inside the measuring tube, and there will be no entanglement or blockage. There is almost no pressure loss, and it can work reliably and continuously for a long time.

4. Wide measurement range: The flow velocity measurement range can reach 0.05m/s~10m/s.

5. High measurement accuracy: ± 0.5%~± 1.0%.

6. Measurement stability: The measurement accuracy is not affected by changes in physical parameters such as temperature, pressure, viscosity, and density of the measured medium.

7. It has the function of pulse output and GSM wireless data remote transmission.

3、 Selection of lining for lithium battery electromagnetic flowmeter

Lining material	Main performance	Maximum medium temperature		Scope of Application
Lining material	Main performance	Integrated type	Separated type
Polytetrafluoroethylene（F4)	It is a chemically stable plastic that can withstand boiling hydrochloric acid, sulfuric acid, nitric acid, and aqua regia, as well as concentrated alkali and various organic solvents. Not resistant to corrosion from chlorine trifluoride, high-temperature chlorine trifluoride, high flow rate liquid fluorine, liquid oxygen, and auto oxygen.	70℃	100℃ 250℃ (Special order required)	1. Strong corrosive media such as concentrated acid and alkali. 2. Sanitary media.
Perfluoroethylene propylene（F46)	同F4， Wear resistance and negative pressure resistance are higher than F4.		Ditto.
Polyfluoroethylene（Fs)	The upper limit of applicable temperature is lower than that of polytetrafluoroethylene, but the cost is also lower.		80℃
Polychloroprene rubber	1. Has excellent elasticity, high tensile strength, and good wear resistance. 2. Resistant to corrosion in general low concentration acid, alkali, and salt media, but not resistant to corrosion in oxidizing media.		80℃ 120℃ (Special order required)	Water, sewage, and weakly abrasive slurry.

polyurethane rubber	2Poor corrosion resistance.		80℃	Neutral strong abrasion slurry, coal slurry, mud

4、 Selection of electrode for lithium battery electromagnetic flowmeter

electrode material	Corrosion resistance and wear resistance
stainless steel0Crl8Nil2M02Ti	Used for weakly corrosive media such as industrial water, domestic water, sewage, etc., suitable for industrial sectors such as petroleum, chemical, steel, as well as municipal and environmental protection fields.
HastelloyB	It has good corrosion resistance to all concentrations of hydrochloric acid below boiling point, as well as to non chlorinated acids, bases, and non oxidizing salt solutions such as sulfuric acid, phosphoric acid, hydrofluoric acid, and organic acids.
HastelloyC	Can withstand corrosion from non oxidizing acids such as nitric acid, mixed acids, or mixed media of chromic acid and sulfuric acid, as well as oxidative salts such as:Corrosion under Fc+, Cu+or with other oxidants, such as corrosion in hypochlorite solutions above room temperature or seawater
Titanium	Capable of withstanding seawater, various chlorides and hypochlorites, and oxidizing acidsCorrosion caused by (including fuming sulfuric acid), organic acids, and alkalis. Not resistant to the corrosion of relatively pure reducing acids (such as sulfuric acid, hydrochloric acid), but if the acid contains oxidants (such as nitric acid, Fc+, Cu+), the corrosion is greatly reduced.
Tantalum	It has excellent corrosion resistance and is very similar to glass. Except for hydrofluoric acid, fuming sulfuric acid, and alkali, it can almost withstandCorrosion of a chemical medium (including boiling point hydrochloric acid, nitric acid, and sulfuric acid below 50 ℃). Dig in alkali; Corrosion resistance.
Platinum/titanium alloy	Can withstand almost all chemical media, but not suitable for aqua regia and ammonium salts.
Stainless steel coated with tungsten carbide	Used for non corrosive and highly abrasive media.
Note: Due to the wide variety of media and the complex factors such as temperature, concentration, and flow rate that affect their corrosiveness, this table is for reference only. Users should make their own choices based on the actual situation, and if necessary, conduct corrosion resistance tests on the selected materials, such as hanging plate tests.
