Measuring Water and Liquid Level in Narrow, Obstructed Tanks with 80 GHz Non-Contact Radar Technology

80GHz Level Sensor

The Foxboro Schneider Electric 80 GHz Radar (FMCW) Level Transmitter is ideal for measuring level of water and other liquids liquids in narrow tanks with internal obstructions.

The Schneider Electric (Foxboro) LR75 is a non-contact radar level transmitter that uses FMCW technology. It measures distance, level and volume of liquids and pastes. It has an empty spectrum function that filters false reflections caused by equipment inside the tank.

  • LR75 Free Space Radar
  • 80 GHz FMCW technology
  • cQPSus XP
  • 4 -20mA /HART® 7
  • 1/2" NPT Cable Entry
  • Backlit Display
  • (-14.5..580 psig) I (-40 deg F to +302 F) / FKM/FPM Process Seal
  • 1-1/2“ DN40 Lens Antenna
  • 1-1/2“ NPT ASME Process Connection
  • Very low cost of ownership

Wastewater Treatment Facilities Being Solicited to Test for Coronavirus


New studies show that SARS-CoV-2, the virus causing COVID-19, is shed in stool meaning it’s collecting in city sewers. 


Biobot, Somerville, Massachusetts company specializing in wastewater epidemiology, is establishing protocols to test sewage for SARS-CoV-2. If successful, this data will give communities a dynamic map of the virus as it spreads to new places.

Data from sewage will enable communities to:
  1. Measure the scope of the outbreak independent from patient testing or hospital reporting, and include data on asymptomatic individuals,
  2. Provide decision support for officials determining the timing and severity of public health interventions to mitigate the overall spread of the disease,
  3. Better anticipate likely impact on hospital capacity in order to inform hospital readiness and the necessity of public health interventions,
  4. Track the effectiveness of interventions and measure the wind-down period of the outbreak, and
  5. Provide an early warning for reemergence of the coronavirus (if it does indeed have a seasonal cycle).
How it works:
  • Biobot will ship participating facilities a sampling kit and sample collection protocols. Each sampling kit includes supplies for transporting one sewage sample, an ice pack, a return shipping box and label, and instructions.
  • Wastewater facilities will collect 24-hour composite samples, and ship the samples back to Biobot laboratories.
  • Biobot will process the sewage samples to concentrate and inactivate viruses.
  • MIT Alm Lab will apply a RT-PCR protocol, adapted from published testing protocols, to detect the SARS-CoV-2 virus.
  • Biobot will communicate the test results back to participating communities.
How to receive sampling kits:

Radar Level: The Relationship Between Frequency and Beam Angle and Using Beam Angle Calculators


Radar is the preferred technology for level measurement in many of today’s industrial applications. Selecting the best microwave frequency transmitted by the device for your application is crucial, and understanding the relationship between frequency and beam angle is very important.

In this video, Jeff Blair, Offer Manager for level products at Schneider Electric, presents the difference in beam angle at various frequencies and how to use Beam Angle Calculators to determine beam width at various levels in a tank.
