Radar Level Sensor For Storage Tanks | 80GHz FMCW Non-Contact Level Transmitter

The Radar Level Sensor for Storage Tanks is a universal 76–81GHz FMCW non-contact radar level transmitter specially optimized for conventional industrial storage tank measurement scenarios. Designed for large and medium-sized vertical and horizontal storage tanks, this sensor adopts a standard optimized beam design, fully enclosed PTFE lens antenna and PTFE-lined stainless steel flange structure. It stably measures various conventional liquid media including corrosive liquids and steam-containing process fluids, solving common tank measurement problems such as surface foam, slight vapor interference and internal structural echo disturbance. With a maximum measuring range of 60m, stable ±5mm industrial-grade precision and dual explosion-proof certification, it is the standard universal level monitoring solution for chemical, petrochemical, environmental protection and municipal storage tank systems. Multiple customized configurations are available to match special storage tank working conditions.

Industrial storage tanks face universal measurement pain points that ordinary level instruments cannot fully solve. Traditional floating ball level gauges and ultrasonic sensors are susceptible to liquid foam, steam volatilization, temperature fluctuation and tank internal structural obstacles, resulting in unstable data, large errors and frequent maintenance. Conventional narrow-beam radar sensors over-designed for small narrow tanks cause functional redundancy and cost waste when applied to large-diameter storage tanks.

This dedicated storage tank radar level sensor adopts industry-standard 80GHz high-frequency FMCW radar technology tailored for general storage tank operating environments. The optimized beam angle perfectly adapts to large-diameter tank structures, effectively filtering false echoes generated by tank walls, baffles and heating coils. The non-contact measuring method avoids direct contact with process media, eliminating probe corrosion, medium adhesion and wear failure risks that exist in contact measuring equipment.

Different from narrow-tank dedicated radar with ultra-narrow beam and ultra-high precision, powder silo radar for heavy dust environments and interface guided wave radar for medium layering monitoring, this product focuses on universal adaptability, stable long-term operation and cost-effectiveness for conventional storage tanks. It balances anti-corrosion performance, vapor interference resistance and environmental adaptability, covering most normal-pressure and medium-pressure liquid storage tank working conditions. For ultra-high pressure, ultra-low dielectric medium and special large-span storage tanks, our engineers can recommend matched upgraded models.

Q1: What is the difference between storage tank radar and narrow small vessel radar?

This storage tank dedicated radar adopts standard beam configuration and industrial-grade ±5mm precision, optimized for large-diameter conventional storage tanks with internal baffles and heating coils. The small vessel radar uses 3° ultra-narrow beam and ultra-high precision, specially designed for narrow-diameter confined tanks. This model is more cost-effective and universal for conventional storage tank projects.

Q2: Can it measure liquid level with foam and steam on the surface?

Yes. The 76–81GHz high-frequency radar has strong penetration capability. It can penetrate most thin foam layers and steam vapor, lock the real liquid level surface, and effectively avoid measurement failure caused by surface interference of storage tanks.

Q3: Is the PTFE antenna suitable for long-term storage tank operation?

Absolutely. The fully enclosed PTFE lens antenna and PTFE-lined flange have excellent resistance to corrosion, high temperature and medium adhesion. It will not be corroded by chemical liquids or contaminated by steam condensate, adapting to long-term unattended operation of industrial storage tanks.

Q4: Does the product support remote centralized management?

Yes. In addition to local on-site debugging, it supports 4-20mA/HART and RS485 signal output, matching industrial control system access. The dedicated PC software realizes remote parameter configuration, data viewing and fault diagnosis, which is convenient for centralized management of multiple storage tank equipment.
