Selection of instruments for oil depots
Thread Content
What type of level gauge should be used for oil storage tank levels, and what type of flow meter should be used?
For level gauges on storage tanks, radar-type or servo-type models are recommended; naturally, foreign-made products perform better. For flow meters, it is recommended to choose mass flow meters or positive displacement flow meters, such as those with twin rotors or gear wheels.
For oil depot flow meters, it is recommended to use helical rotor flow meters, also known as twin-rotor flow meters, which offer high precision and are primarily used for trade settlement purposes. http://www.shakic.com/cp/OVAL%20UF-II%20spiral%20gear%20flowmeter.htm
Level gauge: radar, commonly used in servo systems； Flow meters generally include positive displacement flow meters, mass flow meters, etc
Level gauge: Servo-type ones are better for large storage tanks； Flow meter: Use a positive displacement flow meter.
Radar level gauges are widely used for large tanks; nowadays, radar devices are basically used in all cases

Reply to 6# zhangleitong: Horn-shaped ones are used more often, while wave-guiding types are used less frequently. Another point is that, in the case of renovation projects, if the original opening is small, then guided wave radar should be used
Level measurement: radar. Flow measurement: high precision is required; it is generally used for billing or economic evaluation, and mass flow meters are employed for this purpose, with imported ones being the best choice. For routine operation monitoring, conventional flow meters can be used; it is recommended to use high-precision mass flow meters – those made by Taihang and Xi’an are both excellent options.
Reply to 8# zhangleitong: It is determined by the range; 100 is more than sufficient
Reply to 10# zhangleitong: For 4 meters, a 78mm speaker can be used, along with a 80mm flange； For 9 meters, a 98 speaker and a 100 flange can be used, or a 78 speaker and an 80 flange can be used ；
