Description

The MQ8010 is an entry-level, highly compact 80GHz FMCW radar level transmitter designed specifically for straightforward liquid level monitoring in non-hazardous, standard-temperature environments. Engineered as a maintenance-free alternative to traditional ultrasonic sensors, it provides reliable non-contact measurement that is completely unaffected by steam, condensation, or temperature fluctuations.

With a focused 10-meter measuring range and a compact physical footprint, the MQ8010 is optimized for tight, shallow, or enclosed spaces where longer-range industrial radars are unnecessary and cost-prohibitive.

Where the MQ8010 Excels:

  • Water & Wastewater Utility: Ideal for pump stations, wet wells, lift stations, and municipal sewage channels.

  • Small Storage Tanks: Perfect for chemical dosing tanks, water storage, and mixing vessels under standard temperatures.

  • Open Channel Flow: Excellent for monitoring water levels in flumes, weirs, and small irrigation ditches.

 

Features

  • Simplified Installation: The built-in bubble level on top of the housing allows operators to visually align the radar perpendicular to the liquid surface instantly, preventing echo loss during setup.

  • No Maintenance Required: Unlike ultrasonic sensors, 80GHz radar does not suffer from condensation buildup or signal degradation from steam and temperature changes.

  • Blind Zone Minimalist: With a minimal blind zone of just 20 cm ($0.2text{ m}$), you can maximize the usable storage volume of your shallow tanks and sumps.

  • Chemical-Resistant Housing: The polycarbonate and fiberglass enclosure is lightweight, corrosion-proof, and designed to withstand damp, humid, and aggressive wastewater environments.
