Pulse Radar Level Meter

Reliable non-contact level measurement designed for tough industrial environments.
The 26 GHz Pulse Radar Level Meter is designed for reliable, non-contact level measurement in liquids, corrosive chemicals, powders, granules, and dust-heavy solid applications. Its high-frequency, narrow-beam radar signal delivers stable performance even in conditions where traditional instruments struggle—such as steam, condensation, foam, buildup, or heavy dust. With multiple antenna options and robust housing materials, it adapts to liquids or bulk solids across chemical, water treatment, energy, mining, and food industries.
Unlike low-frequency radar or mechanical measurement methods, the 26 GHz pulse radar focuses energy more effectively, providing strong anti-interference capability, shorter blind zones, and better performance in narrow vessels and long silos. Its pulse-based signal and extremely low emission power make it suitable for metal and non-metal tanks, while ensuring safe, long-term operation.
While the device uses time-of-flight radar technology, the real value lies in how it performs on site: consistent measurement without being affected by temperature, pressure, density, viscosity, or changes in the medium —without frequent recalibration or process interruption.

To ensure optimal performance, the flowmeter must be installed correctly. Key considerations include:

  • Location: Install away from strong electromagnetic fields, severe vibrations, and extreme temperature fluctuations. Ensure the pipeline remains full of the measured liquid.

  • Straight Pipe Requirements: For accurate readings, a straight pipe length of at least 10 times the pipe diameter (10D) is required upstream of the flowmeter, and at least 5 times the pipe diameter (5D) downstream.

  • Mounting Base: The mounting base must be welded perpendicular to the measured pipeline. Ensure the hole size in the pipeline matches the outer diameter of the through-hole on the mounting base.

  • Insertion Depth:

    • For pipes with a diameter (D) ≤ 400mm, the insertion depth (E) is calculated as: E = H – 0.5D (where H is the distance from the transducer electrode to the directional indicating arm).

    • For pipes with a diameter (D) > 400mm, the insertion depth is calculated as: E = H – 0.121D.

  • Grounding: Proper grounding is critical to prevent electrical interference. The ground terminal must be connected to the measured medium. The resistance should be less than 10Ω.

Maintenance and Troubleshooting:

  • Routine Maintenance: The transducer generally does not require scheduled maintenance. However, for media prone to causing scaling or buildup, periodic cleaning of the electrode and measuring head is necessary to maintain accuracy.

  • Troubleshooting: A troubleshooting guide is provided in the instruction manual to diagnose common issues such as negative flow readings, overrange output, or signal fluctuations. For complex issues, please contact our technical support. Do not attempt to repair the unit yourself. Always switch off the ball valve before dismounting the transducer.

The plug-in electromagnetic flowmeter is ideally suited for large-diameter, low-to-medium pressure pipelines requiring reliable conductive liquid flow monitoring.

  • Water supply and distribution networks — main pipeline flow measurement.

  • Wastewater treatment systems — inflow/outflow monitoring, pump station control.

  • Power plant utilities — circulating cooling water, condensate flow measurement.

  • Industrial process water — chemical, metallurgy, paper-making, and irrigation systems.

  • Retrofit and energy management projects — when replacing or upgrading existing flow measurement points.
