1. Void fraction measurement (A v/A) a) Capacitance measurement b) Optical characterization 2. Quality measurement (m v/m) These techniques are for the most part all used in classical fluid flows. The unique “cryogenic” features have to do with instrumentation used to . The ultrasonic testing instrument shall utilize an amplitude control accurate over its useful range to ± 20% of the nominal amplitude ratio, to allow measurement of indications beyond the linear range of the vertical display on the screen, the procedure for evaluating amplitude control linearity is given in appendix 2 of article 5, ASME code. Title: Ultrasonic Testing 1 Ultrasonic Testing 2 Introduction. This module presents an introduction to the NDT method of ultrasonic testing. Ultrasonic testing uses high frequency sound energy to conduct examinations and make measurements. Ultrasonic examinations can be conducted on a wide variety of material forms including. Intense ultrasonic radiation has disraptive effect on liquids by causing bubbles to be formed. Applications of Ultrasonic Waves. Ultrasonic waves are used for the following purposes. Ultrasonic flaw detection. Cutting and matching of hard materials. Ultrasonic soldering and welding. Measurement of flow devices. Applications in medicine. Thermal.

Ultrasonic; Ultrasonic. Ultrasonic flow transmitters are sensors with electrical transmission output for remote indication of liquid flow rate. Models are cost effective, compact, and lightweight. Applications include treated water, river water, diesel oil, datalogging, flow measurement . Ultrasonic Testing (UT) uses high frequency sound energy to conduct examinations and make measurements. Ultrasonic inspection can be used for flaw detection/evaluation, dimensional measurements, material characterization, and more. To illustrate the general inspection principle, a typical pulse/echo inspection configuration as illustrated below. Ultrasonic; Ultrasonic. Ultrasonic level transmitters are sensors with an electrical transmission output. Explosion-proof, remote sensor, and cellular models available. Applications include process tanks, chemical processing, and water & wastewater. Ultrasonic technology with temperature compensation provide accurate and reliable measurements. Ideal when conditions are in need of non-contact liquid level measurement, but ultrasonic level measurement is not acceptable. Can be designed for your specific level measurement needs.

  Process analysis by use of ultrasonic measurements can be accomplished by the "pulse echo" technique or the "pulse transmission" technique (Figure 5). The pulse echo technique uses only a single ultrasonic transducer, which serves as a transmitter and a receiver simultaneously. Ultrasonic methods of NDT use beams of mechanical waves (vibrations) of short wavelength and high-frequency, transmitted from a small probe and detected by the same or other probes. Such mechanical waves can travel large distances in fine-grain metal, in the form of . Ultrasound can also provide additional information such as the depth of flaws in a welded joint. Ultrasonic inspection has progressed from manual methods to computerized systems that automate much of the process. An ultrasonic test of a joint can identify the existence of flaws, measure their size, and identify their location. Prosonic Flow B is the specialist for accurate and reliable measurement of wet biogas and digester gas,even under fluctuating process conditions. With its unique integrated real-time methane fraction analysis, Prosonic Flow B enables continuous measurement and monitoring of .
