1. Features and Applicable Operating Environment:

A magnetic flow transmitter is suitable for use in a variety of harsh environments. Power supply options include 85V-265V AC, 24V DC, battery power, and solar power. Suppose you need to install the device in an area without electrical infrastructure and need to manage the flow meter through a control system. In that case, you can choose a battery-powered model with MODBUS protocol or a battery-powered model with pulse output. These models come standard with IP68 protection, effectively meeting your measurement and control needs.

Mag flow transmitters are instruments that can measure all conductive liquids. They occupy a key position in the measurement industry due to their high accuracy, strong stability, no obstructing components in the pipeline, low maintenance costs, and long service life.

2. Most Popular Specifications:

Before purchasing an electromagnetic flowmeter, you need to customize the various components of the device based on the properties of the liquid being measured. This describes the most common configurations:

※For measuring non-corrosive liquids such as sewage and wastewater, a rubber lining and SS316 electrodes can be used.

※ For measuring sanitary liquids such as drinking water, beer, and milk, a PTFE lining and SS316 electrodes can be used. Stainless steel, such as SS304 or SS316, is recommended for the sensor.

※For measuring acidic liquids, a PTFE lining and Hastelloy electrodes are recommended. For measuring alkaline liquids, a PTFE lining and titanium or tantalum electrodes are recommended. Stainless steel is recommended for the housing, as corrosive molecules in the operating environment can damage the sensor housing over time. Using stainless steel will significantly extend the service life.

3. Classification:

※ Insertion-type Magnetic Flow Transmitter, which consists of a magnetic sensor inserted into the fluid. This type of transmitter is very suitable for use in large pipelines or open channels, with low cost of use, simple installation, and high accuracy.

※ Integrated online flow transmitter, which is directly installed in the flow pipeline. This type of transmitter is best suited for applications with low flow rates or where the fluid is abrasive or corrosive. In-line flow transmitters are also typically more compact than insertion-type flow transmitters, making them easier to install and maintain.

※ Separate online flow transmitter, the sensor is installed in the pipeline, the converter and the sensor are separated (the standard configuration is 10*2 cable, but the cable length can be customized). This type is more suitable for installation in deep wells or sites with relatively high pipeline positions, especially in deep wells, and can be made with an IP68 protection level, so that if there is water in the deep well, it will not affect the normal operation of the instrument.

6. Lining Options:

The selection of the lining of the Magnetic Flow Transmitter is very important: according to the characteristics of the measured liquid, such as the temperature of the medium, corrosiveness (PH value), whether the liquid contains impurities, etc., selecting the most suitable lining material is key to ensuring that the flowmeter's working life is key to measurement accuracy.
Available lining materials are as follows:

lining	Features
Neoprene Lining	Oil resistance, solvent resistance, oxidation resistance, corrosion resistance to general acid, alkali, salt and other media, but not corrosion resistance to oxidizing media. Has excellent elasticity and wear resistance. But cold resistance is poor. *Scope of application: 1.0°C-80°C non-strong acid, strong alkali, strong oxidizing medium. Can measure less abrasive sewage, mud, and slurry.
polyurethane rubber	* Has excellent wear resistance and elasticity. However, its acid and alkali resistance is poor, so it cannot be used in water mixed with organic solvents. *Scope of application: -2.5 degrees -60 degrees, suitable for neutral and strong abrasive pulp, coal slurry, mud, paper pulp, domestic sewage, waste water.
Polytetrafluoroethylene (PTFE)	*PTFE is the material with the most stable chemical properties among plastics; it is resistant to boiling hydrochloric acid, sulfuric acid, nitric acid, aqua regia, concentrated alkali, and various organic solvents, but it is not resistant to chlorine trifluoride, high temperature oxygen fluoride, large flow liquid fluorine, liquid Corrosion by oxygen and ozone. B. Poor wear resistance and negative pressure resistance. C. Scope of application: -25 degrees to -140 degrees, strong corrosive substances such as concentrated acid and alkali, drinking water, milk, beer, beverages, and other sanitary media.
Fluorinated Ethylene Propylene (F46)	* Hydrophobic and non-stick. Corrosion resistance is second only to PFA. When the negative pressure resistance requirement is high, a metal mesh can be installed to improve the negative pressure resistance capacity. * Poor abrasion resistance. *Scope of application: -25°C-100°C non-strong abrasive media, sanitary media.

7. Electrode Type:

Electrodes material	Main performance and application
SS316L	Used for industrial water, life water, sewage, etc, with weak corrosion; applicable to the petroleum, chemical, metallurgy industries, and municipal and environmental protection fields;
HB	With good corrosion resistance performance to all concentrations of hydrochloric acid below the boiling point; also resist sulfuric acid, phosphoric acid, hydrofluoric acid, organic acid, and other non-oxidizing acids, alkaline, and hydrochloric acid, etc.
HC	Resist non-oxidizing acid, such as the mixture of nitric acid/chromic acid and sulfuric acid; and resist oxidizing salt, such as Fe3+, Cu2+, and other oxidizing agents like hypochlorite solution and seawater, etc.
Titanium	Resist seawater, kinds of chlorides, hypochlorite, oxidizing acid(including nitrosonitric acid), organic acid, alkali, etc, but not resist purified reductic acid(sulfuric acid, hydrochloric acid); Corrosion will reduce greatly when it has only oxidizing agent(like nitric acid and ionic mediums with Fe, Cu) in the acid.
Tantalum	Good corrosion-resistant property, similar to glass; it could almost resist all chemical media (including boiling hydrochloric acid, nitric acid, and sulfuric acid below 17 °C5), but not hydrofluoric acid, strong sulfuric acid ,and alkali.
Platinum-iridium alloy	Used for all chemical substances, resistant to corrosion (such as acid, alkali, various salts), but not resistant to aqua regia.
