VEGA VEGAPULS 64 Radar Level Sensor

Overview

The VEGA VEGAPULS 64 is a non-contact radar sensor for continuous level measurement of liquids, built around 80 GHz technology and an 80 mm antenna that produces a beam angle of just 3 degrees. With a dynamic range of 120 dB, it measures practically any liquid with great reliability, from aqueous media to hydrocarbons and liquid gases, regardless of dielectric constant.

With fast quotation turnaround and technical support, Seven Star LLC proudly supplies the VEGA VEGAPULS 64 to process plants and storage facilities across the Sultanate of Oman and the wider GCC, backed by genuine factory calibration, full documentation, and local technical support.

Measurement Principle

The VEGA VEGAPULS 64 operates with a continuous, frequency-modulated radar signal at 80 GHz. A focused microwave signal is emitted toward the liquid surface, reflects, and returns to the sensor; the frequency difference between the emitted and the received signal is proportional to the distance and is converted into the level reading. Special software algorithms filter out interference caused by buildup on the antenna system, and the sensor’s high dynamic range compensates for signal attenuation from product deposits.

Because the measurement is entirely non-contact and independent of process conditions, the VEGAPULS 64 delivers exact results even with condensate, buildup, or agitators present in the vessel. Its very good signal focusing, a direct result of the 80 GHz frequency and compact antenna, allows reliable use in vessels with numerous internal installations such as stirrers and heating spirals.

Engineering Design of the VEGA VEGAPULS 64

The sensor measures ranges up to 30 m with an accuracy of ±1 mm, and is available with a plastic horn antenna, thread with integrated horn antenna, flange with encapsulated antenna system, or hygienic fitting, in wetted materials including PFA, PTFE, 316L, Alloy C22, and PEEK. It is rated for process temperatures from –196°C to +200°C and pressures from –1 to +25 bar.

The very small process fittings make the VEGAPULS 64 particularly suited to small storage or process vessels where larger antenna systems will not fit. The housing is available in plastic, aluminum, or stainless steel, with protection ratings up to IP66/IP68, and communicates via 4–20 mA/HART for straightforward integration with plant control systems.

Key Features

The VEGA VEGAPULS 64 is engineered for reliable non-contact level measurement of liquids, and the VEGA VEGAPULS 64 is a proven solution across small storage vessels and complex process tanks alike:

• Delivers measurement accuracy of ±1 mm across measuring ranges up to 30 m.
• Uses 80 GHz radar with a 3 degree beam angle for precise signal focusing past internal obstructions.
• Achieves a 120 dB dynamic range, measuring practically any liquid regardless of dielectric constant.
• Remains reliable with condensate, buildup, or product deposits on the antenna.
• Handles process temperatures from –196°C to +200°C and pressures from –1 to +25 bar.
• Offers hygienic fitting options suitable for pharmaceutical and food production vessels.
• Features very small process fittings, ideal for compact storage or process vessels.
• Is wear-free and maintenance-free thanks to its non-contact measuring principle.

Industrial Applications

The VEGA VEGAPULS 64 is specified for continuous level measurement of liquids in the pharmaceutical and chemical industries, food production, energy generation, and water management, including complex mixing tanks with agitators and small process vessels where compact fittings are essential. Its wide dielectric-independent measurement range also suits hydrocarbon and liquid gas storage.

With engineering support in Muscat, Seven Star LLC supplies the VEGAPULS 64 to industrial and process facilities throughout Oman and the GCC, including projects in the Sohar and Salalah economic zones, chemical processing plants, and food and beverage production sites, with lead time confirmed at quotation and technical support with selection.

Technical Specifications

Key technical parameters for the VEGA VEGAPULS 64 are summarized below.

VEGAPULS 64 signal evaluation and antenna versions

According to the VEGA specification sheet, the VEGAPULS 64 emits a continuous radar signal through its antenna rather than discrete pulses. The echo reflected by the liquid is received by the same antenna, and the frequency difference between the emitted and the received signal is proportional to the distance. From this the electronics calculate the filling height and issue it as a 4 to 20 mA/HART two-wire signal.

VEGA lists four mechanical versions: a plastic horn antenna with 80 mm diameter, a thread with integrated horn antenna, a flange with encapsulated antenna system and a hygienic fitting with encapsulated antenna system. Threads start at G3/4 and 3/4 NPT, flanges at DN50 and 2 inch. Hygienic connections include clamp and slotted nut fittings from 2 inch / DN50, a 65 mm DRD connection and a NEUMO BioControl D50 PN16 fitting.

VEGAPULS 64 housings, approvals and successor status

Housings are offered in plastic, aluminium and stainless steel, the latter as precision casting or electropolished, in single or double chamber form. VEGA states protection ratings of IP66/IP67, IP66/IP68 (0.2 bar) and IP66/IP68 (1 bar). Process seals are available in EPDM, FKM and FFKM, the permitted ambient temperature is -40 to +80 °C, and the two-wire electronics run on 12 to 35 V DC.

Listed explosion protection types are intrinsic safety, flameproof enclosure and dust ignition protection, with ATEX, IEC, FM, CSA, UKEX, NEPSI, INMETRO and CCOE among the approval scopes. VEGA also lists 3A, FDA and EC 1935/2004 for food and pharma, WHG and VLAREM II overfill protection and several ship approvals. The VEGA product page marks the VEGAPULS 64 as having a newer successor, the VEGAPULS 6X.

Why Choose Seven Star LLC for VEGA Radar Level Sensors

The VEGAPULS 64’s compact antenna and wetted-material options (PFA, PTFE, 316L, Alloy C22, PEEK) exist precisely because small process vessels and aggressive liquids each demand a different fitting — picking the wrong material on a hydrocarbon or corrosive application undermines the sensor’s dielectric-independent advantage. Seven Star LLC works with your process team to confirm the correct VEGAPULS 64 antenna style and wetted material for your actual liquid and vessel size before order confirmation, backed by our trusted VEGA suppliership across Oman and the wider GCC. We also support chemical, food, and energy facilities in Sohar and Salalah with hygienic-fitting guidance for pharmaceutical-grade vessels and coordinated delivery for multi-point tank instrumentation projects. Where vessels include agitators or heating spirals, we also help confirm the sensor’s signal-focusing performance is adequate for the specific internal layout before installation, avoiding a costly repositioning after commissioning.
