How to use external level gauges correctly

Thread Content

An external level gauge is a device used to measure changes in liquid level, and it is primarily applied in industries such as chemicals, petrochemicals, and oil refining. Let’s take a look at how to use it: Usage requirements: The viscosity of the liquid medium to be measured by the external level gauge should be within 30 MPa·s; the medium cannot be a slurry, emulsion, or suspension, as crystallization can also have an impact. Tank body: Tanks are generally horizontal tanks, vertical tanks, spherical tanks, etc. Stirring inside the tank can have a certain impact, while the use of insulation layers or linings in the container depends on the specific application. https://bbs.hcbbs.com/forum.php?mod=image&aid=2146210&size=300x300&key=4f27065b7edc8fd5&nocache=yes&type=fixnone Temperature: The temperature measured by the external level gauge at present is between -40~150°C; values above this range require customization based on the operating conditions. Measurement: Sonar-type external level gauges have a minimum blind zone; when the liquid level is below the lower limit of the gauge’s measurement range, it cannot measure accurately. Typically, the gauge will display “L0” (related to the tank parameters set in the gauge). https://bbs.hcbbs.com/forum.php?mod=image&aid=2146212&size=300x300&key=47a3b460c5336edc&nocache=yes&type=fixnone Probe installation: The measurement probe features a magnet ring made of highly magnetic material, which ensures that the force of adhesion to the container wall exceeds 80 kg, thus guaranteeing a more secure installation of the probe. Non-magnetic tanks are installed using bonding or welding methods.
