Shanghai Hongyi Magnetic Flip Plate Liquid Level GaugeMagnetic Level Gauge is widely used in the industrial field due to its simple structure, intuitive display, high pressure and high temperature resistance, safety and reliability. The following is an analysis of its main application areas and specific scenarios:
1. Oil and gas industry
1) Crude oil and finished oil storage tanks
Application Scenario:
Continuous monitoring of liquid levels in crude oil storage tanks and diesel/gasoline intermediate tanks.
Trade handover measurement (used in conjunction with radar level gauges to improve reliability).
Special requirements:
Explosion proof certification (ATEX/IECEx).
Corrosion resistance to sulfur (NACE MR0175 standard, made of 316L/Hastelloy alloy).
2) Liquefied natural gas (LNG) and liquefied petroleum gas (LPG)
Low temperature adaptation:
Liquid nitrogen and LNG storage tanks (below -162 ℃) are equipped with vacuum insulated magnetic flap level gauges.
The float material is stainless steel+low-temperature treatment to avoid cold brittleness.
3) Offshore platforms and pipelines
High pressure corrosion resistance:
Liquid level monitoring of subsea pipeline separator (pressure up to 25MPa).
Anti corrosion design in salt spray environment (such as titanium alloy shell).
2. Chemical and petrochemical industries
1) Corrosive medium
Strong acid and strong alkali:
Sulfuric acid and hydrochloric acid storage tanks: lined with PTFE or made of full plastic (PP/PVDF) material.
Sodium hydroxide solution: stainless steel+PTFE seal.
Organic solvents:
Benzene, xylene, etc.: anti permeation float (ceramic coating).
2) Reactor and Tower
High temperature and high pressure:
Aggregation reactor (temperature ≤ 400 ℃, pressure ≤ 10MPa).
Distillation tower interface measurement (oil water vapor three-phase separation).
3. Electricity and Energy
1) Thermal power plant
Boiler drum water level:
High temperature and high pressure steam environment (≤ 450 ℃, PN25), dual color magnetic flip plate (red and green display are more prominent).
Safety redundancy: parallel connection with differential pressure transmitter, in compliance with ASME B31.1 standard.
2) Nuclear power
Nuclear grade certification:
Reactor auxiliary system liquid level monitoring (made of radiation resistant materials, IEEE 344 seismic standard).
3) New energy
Hydrogen energy: Liquid hydrogen storage and transportation (-253 ℃ ultra-low temperature adaptation).
Energy storage power station: electrolyte (such as vanadium batteries) level control.
4. Pharmaceutical and food industries
1) Sanitary grade applications
GMP compliance:
Aseptic storage tanks and fermentation tanks: designed for hygiene (3A/SMS certification), with quick release flanges for easy CIP cleaning.
No dead corner structure, surface roughness Ra ≤ 0.8 μ m.
2) High purity medium
Water for injection (WFI):
316L stainless steel with electric polishing to prevent microbial growth.
5. Water treatment and environmental protection
1) Municipal sewage
Sludge interface monitoring:
Install anti fouling scraper to prevent the float from being wrapped in sludge.
2) Industrial wastewater
Corrosive wastewater:
Wastewater containing heavy metals (such as electroplating solution): PP material+ceramic float.
