Selection for level measurement in petrochemical industries
Thread Content
Various level measurement instruments have their own operating conditions and ranges of application. When it comes to double-flange, float, guided-wave radar, RF, and all the other types available, what determines which one should be chosen? Is it temperature? Pressure? Corrosion? Cost? Accuracy?
1. Based on past experience and precedents； 2. In combination with practical applications 3. In accordance with **standards 4. Consult the manufacturer
Personal opinion: Double flanges are used for sealed, pressurized containers and tanks. For some viscous liquids, flange-type level gauges with diaphragms are not suitable; guided wave radar can be an alternative. I’m not very familiar with other options. In terms of cost, radar sensors are more expensive than double flanges
1. Tank height: Some level gauges are proportional to the height； 2. Tank medium: whether it is corrosive, viscosity, temperature, pressure, etc ； 3. Measurement accuracy: What level of precision is required? ； 4. Measurement stability 5. Remote transmission capability 6. Other functions, such as water level and density measurement, etc
