Regarding the level gauge for the transfer tank
Thread Content
Requirements: 1. Enameled steel transfer tank with a height of 1.5 meters. 2. The maximum temperature of the material can reach 130°C. 3. Crystallization occurs when the temperature drops. 4. DN50 flanges. 5. Limited headspace above. Could someone please advise on which type of level gauge would be suitable? Originally, a float level gauge made of PTFE was used; after being used once or twice, the float, which moved up and down due to the crystallization of the material, got stuck in the middle position and continued to show that same reading. We considered radar level gauges, but they have blind spots of their own; after accounting for those blind spots, the measurable range is only a little over 1 meter.
Differential pressure level gauge (insulation must be considered; pressure tapping at the lower flange is required to prevent crystallization), with ultrasonic level sensor attached on the outside
What is the liquid level value required by the process for measurement? The blind zone of radar level gauges is not that severe; for materials prone to crystallization, it is recommended to use contactless level gauges.
For similar operating conditions, we use high-temperature radio admittance; the level measurement is not very accurate, but it works fine for basic use. The radar must take into account temperature resistance as well as whether the dielectric constant of the medium meets the requirements. Radar is generally used in areas such as tank farms or open-type equipment, where it performs well; in my experience, it doesn’t work well with other devices that are subject to temperature and pressure changes.
We’ve learned how to make the radar contact-based
A 120G high-frequency radar is used; it does not come into contact with the material, and the crystallization of the material has no impact on the measurements. AC Q: 6274240
