Bitumen And Asphalt Level Meters: Let’s Learn More About Them

Bitumen is a byproduct of crude oil. The quality of bitumen and ease of production depends on the source and type of crude oil from which it is derived. On the other hand, Asphalt is a composite material with two primary ingredients: aggregates and bitumen.

Bitumen and asphalt are hypercritical materials in construction, road paving, and waterproofing applications. Observing their levels in storage tanks, silos, or transportation containers is necessary for operational efficiency and quality control.

In this blog post, we will explore bitumen and asphalt level meters in detail.

Significance of Bitumen & Asphalt Level Meters

• Operational Efficiency: Preventing overflows or shortages.
• Inventory Management: Ensuring accurate stock monitoring.
• Process Control: Maintaining consistency in production.
• Safety Compliance: Reducing risks associated with handling high-temperature, viscous materials.
• Cost minimization: Reducing material wastage and optimizing procurement.

Difficulties in Bitumen & Asphalt Level Measurement

Asphalt has three main characteristics:

First, asphalt has high viscosity. For liquid media with high viscosity, try not to use guided wave radar level gauges to prevent inaccurate measurements.

Second, high temperature. Under high-temperature conditions, asphalt is prone to produce steam and hang-up.

Third, asphalt is easy to solidify. Asphalt itself has high viscosity, and if it is at room temperature, it is easy to solidify. This should also be paid attention to.

In addition to considering the above content, there is actually another important content that needs to be considered for asphalt measurement, that is, the range of the storage tank. The range of the level gauge is set based on the range of the storage tank, the characteristics of the medium in the tank, and the obstacles in the tank.

Operational Outline of Bitumen And Asphalt Level Meters

Bitumen and asphalt level meters employ various sensing technologies to detect the material level in tanks or silos. The choice of technology depends on factors such as temperature, pressure, and tank design.

1. Radar Level Meters

Radar level meters use high-frequency microwave signals to measure the distance between the sensor and the material surface. They are ideal for bitumen and asphalt due to their ability to:

Features:

• The radar operates at 76-81 GHz;
• Millimeter wave radar has a measurement accuracy of ±1mm and a minimum blind zone of 0.08m~0.1m.
• 3° antenna beam angle to meet the measurement needs of more working conditions;
• A variety of lens antennas have smaller emission angles, more concentrated energy, and stronger echo signals. Under the same industrial and mining conditions, they have higher reliability than other radar products;
• It has stronger permeability and can be used normally even if there is adhesion or condensation;
• The dynamic signal range is larger, and the measurement of low dielectric constant media is more stable;
• Dust-proof and steam-condensation proof;
• In multiple measurement modes, radar response time is less than 1S in fast measurement mode;
• Installation method: thread or flange, clamp optional;

2. Gas pressure-guided liquid level meter

The gas pressure-guided liquid level transmitter is composed of a stainless steel gas cylinder, a stainless steel capillary tube, and a junction box. The liquid level pressure signal collected from the gas in the gas collector transmits the pressure to the sensor through the stainless steel capillary tube. This avoids direct contact between the sensor and the measured medium. They are effective for:

Features:

• The sensor does not contact the measured medium and has high reliability.
• High precision
• Anti-interference
• Measurement of high temperature resistant and corrosive liquids
• Strong long-term stability

Applications of Bitumen & Asphalt Level Meters

1. Road Construction: Monitoring asphalt storage tanks in batching plants.
2. Oil Refineries: Measuring bitumen levels in processing units.
3. Roofing Industry: Managing bitumen levels in waterproofing applications.
4. Industrial Coatings: Ensuring consistent material supply in bitumen-based coatings.
5. Tank Farms: Optimizing bulk bitumen and asphalt storage operations.

Choosing the Right Level Meter

1. Temperature Resistance

Since bitumen and asphalt are stored at high temperatures (often above 150°C), ensure that the level meter can withstand extreme heat.

2. Non-Contact Measurement

Non-contact meters (radar, ultrasonic) are preferred for minimal maintenance.

3. Environmental Factors

Consider factors such as vapor, dust, and pressure variations that could affect sensor accuracy.

4. Installation and Maintenance

Choose a meter that fits within your maintenance capabilities and plant infrastructure.
