Measurement of external liquid level gauge ball tank (liquefied gas) in a petrochemical industry in Hainan

 The main business of the user is the deep processing and sales of light hydrocarbons (C4) and liquefied petroleum gas. There are multiple ball tanks on site for the storage of propylene liquefied gas. The customer has been using an imported brand of radar level gauge for measuring the liquid level of the spherical tank before contacting the external mounted level gauge. After our technical engineers went to the site to understand the situation and combined with the characteristics of the high-pressure vessel on site, such as large temperature difference and inability to open holes, we recommend the following selection:

Model: SER-YW (explosion-proof type), (two-wire system), (small blind spot)

Probe cable length: 20M

Tank type: Ball tank

Measurement range: 0-15000 mm

Output signal: 4-20 mA DC+HART

Power supply: 24V

Temperature: -50 °~80 ° C

Wiring method: two-wire system

Display resolution: 1mm

Measurement error: ± 0.1% FS

Probe usage environment temperature: -50 ℃ to+80 ℃

Operating environment humidity: 15% to 100% RH

Explosion proof grade: Exd Ⅱ CT6Gb;

Liquid level display: LCD display

Calibration equipment: with calibration probe

Special requirement: SIL3 certification

Protection level: IP67;

Installation method: magnetic suction

     After one year of operation and testing, our company's external mounted liquid level gauge runs stably, with real-time tracking of incoming and outgoing liquids, no jumping, overcoming temperature drift interference, and a measurement accuracy of 0.1%. It not only solves the problem of inability to open holes for liquid level measurement in spherical tanks, but also can replace previously imported radar products equally, greatly reducing production costs for users, and is economically and safely recognized by users. We plan to continue using our company's external mounted liquid level gauge for tank measurement in the later stage, and we will also strive to provide customers with higher quality products and services.
