Abstract: This article proposes a nondestructive multichannel sensor for liquid-level detection based on spoof surface plasmon polaritons (SSPPs). A mathematical model for liquid-level sensing is ...

I’ve just come across a no-name non-contact, high-precision 80 GHz mmWave radar sensor for liquid level detection with a 40m range, ±5mm accuracy, and Modbus communication over UART. The 0.15m to 40m ...

SOR’s 2700 Series is a newly launched single- or dual-point level switch using ultrasonic technology to detect the presence or absence of liquid in tanks or vessels. Designed for ease of use and ...

RPS-429AA-40P-IS2 intrinsically safe (IS), ultrasonic sensor achieves precise accuracy in distance measurement and object detection applications. With ATEX, IECEx and C-UL-US certifications, this ...

Abstract: This paper deals with parking space detection by using ultrasonic sensor. Using the multiple echo function, the accuracy of edge detection was increased. After inspecting effect on the ...

Recently I came across some non-contact liquid level sensors and gathered them out of curiosity. They have been available in the market for the past few years, but this time I was lucky enough to get ...

The HC-SR04 ultrasonic sensor uses SONAR to determine the distance of an object just like the bats do. It offers excellent non-contact range detection with high accuracy and stable readings in an easy ...
