Sanitary flow meter
Sanitary Flow Meter
Advantages :
1. The advantages of electromagnetic flowmeters are: simple structure, no rotating parts, no friction, long service life, high measurement accuracy, and reliable performance.
2. The measuring tube of the sensor has no throttle valve and throttle valve components, so there is no additional pressure loss, no blocking problem, suitable for measuring the suspended matter, solid particles, two-phase flow fiber, etc. (such as mud, sewage) , Slurry, pulp), and the viscosity of the slurry).
3. Since the signal is formed in the entire space of the magnetic field, it is the average cross-section of the pipeline, so the straight pipe section from the electrode plane to the upstream end plane of the sensor is relatively short, with a length of 5×D (D = inner diameter).
4. The output signal of the sensor has a precise linear relationship with the average speed of the liquid flow, and the measurement result is not affected by the temperature, pressure, density, viscosity, and conductivity of the liquid (not less than the minimum conductivity), for example: a flow meter calibrated with water It is also suitable for other media without additional correction. Therefore, the measurement accuracy is high and the work is reliable.
5. Sanitary electromagnetic flowmeter with three electrodes, built-in grounding electrode, can effectively prevent the interference of the surrounding magnetic field, also used for non-conductive pipes without additional power connection ring.
6. Electromagnetic flowmeter has no mechanical inertia, sensitive response, instantaneous flow and cumulative flow measurement. It can be combined with a computer to form various automatic detections, and it can also be combined with a control system (such as: PLC control cabinet) to form a quantitative control.

Selection of electrodes material
| Electrodes material | Corrosion resistance |
Hastelloy B | It has good corrosion resistance to all concentrations of hydrochloric acid below the boiling point, and is also resistant to oxidizing acids, alkalis, and non-oxidizing salt solutions such as sulfuric acid, phosphoric acid, and organic acids. |
Hastelloy C | It is resistant to oxidizing acids, such as nitric acid, mixed acids, and also resistant to oxidizing salts. If the hypochlorite solution is higher than normal temperature, seawater will corrode. |
Titanium | It can withstand the corrosion of sea water, various chlorides and hypochlorites, oxidizing acids, organic acids, and alkalis, but is not resistant to the corrosion of relatively pure reducing acids. However, if the acid contains an oxidizing agent, 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 is resistant to corrosion by almost all chemical media |
SS316 | Applicable to industrial/municipal drinking water, wastewater and low corrosive mediums. |
Select lining material
| Lining material | The main performance | The scope of application |
PTFE | 1.The most stable chemical properties of plastics in a material that is resistant to boiling hydrochloric acid,sulfuric acid and aqua regia,but also resistant to concentrated acids and various organic solvents, intolerance chlorine , liquid oxygen, high velocity liquid oxygen, ozone corrosion. 2.Poor wear resistance | Concentrated acid,alkali and other corrosive liquid |

F46 | 1.Corrosion resistance with PTEF. 2.Can withstand low wear and tear. 3.Strong anti-negative pressure. | With PTFE 2.Can be used for low abrasive media |
Neoprene | 1.Have excellent flexibility,a high degree of tensile force,good wear resistance. 2.Resistant to the general low concentrated acid, alkali,salt medium corrosion, corrosion resistant to oxidizing media. | Water, sewage, weakly abrasive mud, pulp |
Polyurethane | 1.Has excellent wear resistance (equivalent to 10 times the natural rubber). 2. acid, alkali performance is poor. 3.Do not use water mixed with organic solvents. | Strong neutral wear pulp, mud ,coal slurry and so on |
