What is the best type of level gauge for use with asphalt as the medium?
Thread Content
Asphalt has a very high viscosity, so the level gauge cannot be chosen casually – which one is the most suitable? Let’s discuss it.

Conventional level gauges such as magnetic flip-type, double-flange, and single-flange types are definitely not suitable; even float-type gauges require careful consideration. The best option is to use non-contact level gauges, such as those based on radar or ultrasonic technology. Of course, the back-pulse type level gauge mentioned by the person above can also be used, as it operates on the principle of differential pressure as well
The float type can’t be used, right? It tends to stick together{:3_53:}
Can media with fluctuations also be used?
You're referring to those small floating balls; some tanks can use those larger lever-type floating balls
The blow-out method for differential pressure level measurement is condition-dependent. 1. There must be a continuous and reliable flow of clean air ； 2. The gas source pressure is relatively stable ； 3. The medium under test is uniform ； 4. There must be no local condensation, especially at the liquid level interface and at the air injection ports.
It must be a non-contact level gauge, which is the most suitable
With incomplete operating conditions and parameters, it is not possible to select the appropriate instrument based solely on the material. Based on the materials, it is preliminarily determined that parabolic antenna microwave radars, double flanges, and float balls can be commonly used.
