Selection of level gauge for esterification reactor

Due to the presence of polymers, asphalt esters in the esterification reactor often cause some traditional level detection devices to operate inaccurately or to fail. Based on the conditions you have provided – namely the temperature and pressure of the medium in the esterification tank, as well as the issue of blockage in the level gauge’s backflow pipe – you can consider the following types of level gauges: 1. Adjustable level transmitters: These devices allow for external adjustments, which prevents the level transmitter from coming into direct contact with the medium and thus reduces the impact of polymers on the equipment. It should be noted, however, that this type of equipment requires a high level of precision in installation. 2. Radar level gauge: The radar level gauge performs non-contact measurement and is not sensitive to changes in the type of medium, temperature, pressure, or density; therefore, it is suitable for measuring the level in reactors under complex conditions such as those found in esterification processes. High-frequency radar level gauges can be considered, as they offer good measurement accuracy. 3. Guided wave radar level gauge: The guided wave radar level gauge is also non-contact, but it uses a guided wave tube to direct the radar waves, enabling accurate measurements even in the presence of surface fluctuations or bubbles and foam in the medium. 4. Ultrasonic level gauge: The ultrasonic level gauge is also non-contact; it measures the liquid level by emitting ultrasonic waves and detecting their reflected waves. However, its performance may be affected in high-temperature and high-pressure environments. When selecting a specific model, you need to decide based on the specific conditions at your site, including factors such as the size of the esterification tank, available installation space, and budget. It is equally important to work with experienced suppliers of automated instrumentation, as they can recommend suitable product models based on your actual application conditions. Finally, it is recommended to conduct a thorough on-site investigation before making a selection, and to communicate with the supplier’s technical staff to clarify key parameters such as the product’s temperature resistance, voltage tolerance, measurement range, and installation method, in order to ensure a more accurate and reliable choice. .

An insert-type double-flange level gauge can be considered; the insertion lengths are available in 50/100/150 mm, with 150 mm being recommended to ensure that the diaphragm is inserted into the equipment. Note that in this case, the level gauge does not come equipped with a root valve ； 2. If the material cannot be conveyed, a non-contact high-frequency radar can be used even in the presence of stirring; it is necessary to list the operating conditions and equipment details, and it is advisable to consult the manufacturer for further information.

The density has changed slightly; it is recommended to use radar

I feel like, hey, it might be pretty good
