One more question: What is suitable for measuring the liquid level of oils with high viscosity?
Thread Content
At normal pressure and 140°C, part of the oil tank is underground, so a bottom-mounted flange for level measurement is not very suitable. If radar is used, will the dirt formed by condensed volatile hydrocarbons affect the measurements?
A single-flange level gauge should work; it can be used for migration
Reply to 1# Visitor: Asphalt can now be measured using radar, even when covered in evaporated oil stains; a specialized parabolic radar can still provide accurate measurements
Torque tube type float level gauges can be used to measure liquids with high viscosity; radar sensors can also be used for this purpose. The key factor is determining which option offers the best cost-performance ratio. Fuel tanks in gas stations are usually 3.5 meters deep, while those in oil depots can be as deep as 35 meters. In such cases, radar sensors are more cost-effective. The specific choice still depends on the measurement requirements.

The buoy on the fourth floor isn’t very precise, but it can still be used. We use internal floating balls and floats, and the floats often need to have their waste removed
Part of the tank is buried underground, so the single-flange level measurement has its limitations
It seems that parabolas are a good choice. Do you know which company in China offers good quality products? The imported goods have become more expensive, and customers can’t accept that
Spherical radar should be used, as it offers a wide measurement range and good precision. Even if there is dirt on the spherical surface, it will accumulate at the bottom of the sphere and drip off, without affecting the measurements!
