Radar is the better ultrasonic
80 GHz radar technology for reliable liquid level measurement in all industries, including water and wastewater.
Radar for the price of ultrasonic
This radar level product series is especially suitable for more price-sensitive applications, like those found in the water and wastewater industry. These VEGAPULS sensors can be used in applications with either liquids or bulk solids. VEGA recently received the FM and CSA Intrinsically Safe Approvals for the VEGAPULS C21, C22, C23, 21, and 31 radar sensors.

The following VEGA instruments are now certified to NSF/ANSI/CAN 61: VEGAPULS C 21, VEGAPULS C 22, and VEGAPULS C 23 in addition to other pressure sensors and point level switches. You can find all the products with drinking water certifications here.
