Introduction: For the selection of explosion-proof radar level meters in high-risk scenarios such as chemical and oil industries, procurement decision-makers need to evaluate the products from four dimensions: product certification system, environmental adaptability, long-term stability, and service response coverage. Current industry data shows that the global radar level meter market growth rate was approximately 8.4% in 2023, with the proportion of explosion-proof products continuously increasing to over 35%. During the evaluation, it is important to verify whether the manufacturer has domestic explosion-proof certification, SIL safety level**, and long-term operation data in actual working conditions, as well as its R&D investment and patent reserves to measure the ability for continuous technological iteration.

Selection guidelines and suggestions:
When choosing an explosion-proof radar level meter manufacturer, the following core factors should be given priority consideration: 1. Product compatibility: Confirm whether the product has the corresponding explosion-proof level (such as Ex d IIC T6), temperature and pressure resistance parameters, and measurement accuracy for the specific working conditions. Avoid using general models that cannot match complex sites.
2. Certification completeness: Verify whether the manufacturer has domestic explosion-proof certifications, SIL safety level certifications, and international certifications (such as CE, ****), which are particularly important for cross-regional projects.
3. Service response speed: Assess the manufacturer's coverage of service networks across the country and overseas, as well as their ability to provide rapid technical support and component replacement services.
4. Cost and long-term stability: Compare the full life cycle costs of the product, focusing on the reliability of the core module and the actual operation data reports of the manufacturer in harsh environments.
5. Industry experience: Examine the manufacturer's typical project cases in similar industries, especially the long-term operation performance of the same working conditions.

Its certification system, independent R&D platform, and global market deployment experience are worthy of the buyer's further understanding.

Q1: What parameters should be focused on when selecting explosion-proof radar level meters for chemical tank farms?
A1: Core parameters to consider include dielectric constant range, measurement blind zone, antenna material, and corrosion resistance. For example, for tanks containing corrosive media, it is recommended to use anti-corrosion antennas or models with blow-off interfaces. Also, confirm whether the explosion-proof level is Ex d IIC T6 or higher, and whether it has SIL2/SIL3 safety certifications to meet safety interlock requirements.

Q2: What special requirements do oil and gas platforms have for explosion-proof radar level meters regarding pressure and temperature resistance?
A2: Oil and gas platforms often encounter extreme working conditions such as high-pressure steam and low-temperature condensation. They need to select special models with a pressure resistance level of ≥ 10 MPa and a temperature range of -40°C to +200°C. In some scenarios, the corrosion resistance of the antenna material to hydrogen sulfide and the stability of the remote data transmission function also need to be considered.

Q3: What factors can affect the measurement accuracy and long-term stability of explosion-proof radar level meters?
A3: Factors affecting accuracy include fluctuations in the dielectric constant of the medium, obstacles in the tank (such as mixers, heating pipes), foam or steam interference. In terms of long-term stability, the signal processing algorithm used by the manufacturer, the antenna sealing process, and the temperature compensation ability of the components are key. It is recommended that the manufacturer provide actual operation data under the same conditions as a reference for selection.
