Ultrasonic Flowmeter Application and Maintenance

1 Introduction

In recent years, with the development of sensor technology and instrumentation technology, the use of ultrasonic pulses to measure fluid flow has developed rapidly. Based on different principles, various types of ultrasonic flowmeters suitable for different appl

Solar cells printed on paper

MIT researchers in the United States demonstrated a new type of printing technology that can print solar cells onto thin, soft materials such as regular toilet paper. Although the use of toilet paper as a substrate is not as efficient as actual solar equipment
