Ultrasonic liquid level sensors, which use pulses of ultrasonic sound to calculate liquid levels, … Major advantages offered by ultrasonic level measurement technique are mentioned below: Ultrasonic level sensors are usually non contact type i.e. Ultrasonic level sensors work by emitting and receiving ultrasonic waves. The audible range for humans is said to be between about 20 Hz and 20 kHz. This page provides easy-to-understand description of advantages and disadvantages of optical sensors and ultrasonic / level sensors. A level sensor is used to measure the level in a flume or weir and converts the level to a flow rate using a Q-H curve (flow versus head). It can handle a range of challenging situations thrown in its direction, ensuring it can offer precise readings in a wide variety of temperatures, as well as high humidity levels. Our ultrasonic sensors , made with piezoelectric crystals, use high frequency sound waves to resonate a desired frequency and convert electric energy into … Advantages and disadvantages of digital multimeter.
