Detailed information of Platinum Ray LDE submersible electromagnetic flowmeter:

1、 Overview of submersible electromagnetic flowmeter:

The measurement principle of the Platinum Ray LDE series submersible electromagnetic flowmeter is Faraday's law of electromagnetic induction. The main components of the sensor are the measuring tube, electrode, excitation coil, iron core, and magnetic yoke housing. It is mainly used to measure the volumetric flow rate of conductive liquids and slurries in closed pipelines. Including highly corrosive liquids such as acids, alkalis, salts, etc. This product is widely used in industries such as petroleum, chemical, metallurgical, textile, food, pharmaceutical, papermaking, as well as in fields such as environmental protection, municipal management, and water conservancy construction. The RL-LDE series submersible electromagnetic flowmeter is a fully intelligent submersible electromagnetic flowmeter developed using our company's advanced technology. Its fully Chinese LCD display electromagnetic converter core adopts a high-speed central processing unit. The calculation speed is very fast, the accuracy is high, and the measurement performance is reliable. The converter circuit design adopts international advanced technology, with an input impedance of up to 1015 ohms, a common mode rejection ratio of better than 100db, and a suppression ability of better than 90db for external interference and 60Hz/50Hz interference. It can measure fluid medium flow rates with lower conductivity. The sensor adopts non-uniform magnetic field technology and a special magnetic circuit structure, which makes the magnetic field stable and reliable, and greatly reduces the volume, reduces repetition, and makes the flowmeter small and flow oriented.

2、 Characteristics of submersible electromagnetic flowmeter products

1. Strong anti-interference ability, almost unaffected by external interference

2. Measurement is not affected by changes in fluid density, viscosity, temperature, pressure, and conductivity

3. Measure the unobstructed flow components inside the tube without pressure loss, and have low requirements for straight pipe sections.

4. There are no movable parts or flow blocking components in the pipeline, and there is almost no negative pressure loss measured

5. Equipped with self checking and self diagnostic functions

6. On site, the range can be modified online according to the actual needs of the user

3、 Selection Table for Lining of Submersible Electromagnetic Flow Meter

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.

4、 Electrode selection table for submersible 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.

Three elements for selecting a submersible electromagnetic flowmeter: flowmeter diameter, electrode material, and lining material

1. Flow meter diameter (determined based on the wall thickness and outer diameter of the flow meter pipeline);

2. Lining material: For normal water flow detection at room temperature, rubber lining is generally selected; The flow detection in the sewage treatment industry generally selects corrosion-resistant polytetrafluoroethylene lining; Choose wear-resistant polyurethane lining for mud, mortar, slurry, etc

3. Electrode material: Conventional 316L stainless steel electrode;

4. RL-LDE electromagnetic flowmeter

IP65 protection level, dustproof and rainproof

Standard 220V power supply, 24V optional, suitable for various occasions

Standard 4-20mA output, supporting standard MODBUS-RTU 485 communication
