Ultrasonic testing (UT) is a family of non-destructive testing techniques based on the propagation of ultrasonic waves in the object or material tested. In most common UT applications, very short ultrasonic pulse-waves with center frequencies ranging from 0.1-15 MHz, and occasionally up to 50 MHz, are transmitted into materials to detect internal flaws or to characterize materials. A common example is ultrasonic thickness measurement, which tests the thickness of the test object, for example, to monitor pipework corrosion. Ultrasonic testing is often performed on steel and other metals and alloys, though it can also be used on concrete, wood and composites, albeit with less resolution.
Sonic testing pipe is specially designed to be encased in foundations such as bored piles, diaphragm walls and barrettes to allow for future testing of the concrete integrity by ultrasonic waves.

Rebar coupler is used to connect the two rebar ends in the construction work. 1. Easy Operation, saving time and rebar material. The rebar coupler producing and rebar end threading will not be affected by the weather; it can be processed before processing. 2. It can connect the rebar with the diameter 14mm to 40mm. 3. Use No.45 steel, with the thickness and length of the rebar coupler, the connecting part has higher tensile strength than the rebar part. size16-40mm.

How to choose the suitable Pulmonary Function Testing device Ultrasonic type is the best choice. In recent years, with the rapid development of modern electronic technology and bioengineering, Pulmonary Function Testing devices are updating continually, and they are more sophisticated and perfected gradually. Traditionally water seal Pulmonary Function Testing device, wedge Pulmonary Function Testing device,� dry rolling-seal Pulmonary Function Testing device are phrased out of market because they could not connect with electronic computers. After 2000, ultrasonic Pulmonary Function Testing devices have been used internationally to replace traditional differential pressure Pulmonary Function Testing device, turbine Pulmonary Function Testing device and thermal Pulmonary Function Testing device. The main reason is that these three principles have some limitations as below: 1. Hygiene problem: it is difficult to clean thoroughly, and there is a very high risk of cross-infection in long-term use; 2. Unable to measure lower flow; 3. Heavy reliance on gas composition and temperature; 4. Calibration and adjustment required
Principles of ultrasonic Pulmonary Function Testing device The ultrasonic time difference method uses a pair of ultrasonic transducers to alternately (or simultaneously) transmit and receive ultrasonic waves. By observing the difference in the propagation time between the upstream and the backward flow of the ultrasonic in the medium (gas or liquid), the fluid velocity is measured indirectly, and then calculate the flow data based on fluid velocity. The flow measurement based on the ultrasonic principle is only influenced by the flow and geometry, and accuracy will not be affected by temperature, gas composition, humidity or pressure. So it is a perfect alternative to differential pressure and turbine principles, and is the best choice for Pulmonary Function Testing device.
Advantages for ultrasonic Pulmonary Function Testing device: 1.No drift, no preheating, no calibration, no maintenance (flow measurement only depends on time measurement and sensor geometry, so no calibration) 2.Non-contact flow detection technology, the ultrasound probe does not touch the patient, preventing cross infection 3.High measurement accuracy, especially for very weak airflow 4.Direct flow measurement, wide linear range, no nonlinear distortion 5.There are no obstacles in the middle of the breathing tube, no breathing resistance 6.Not afraid of water vapor, real-time BTPS correction 7.The sensor is not affected by humidity, air pressure and pollution 8.Can obtain gas concentration information at the same time 9.Greatly expanded the scope of application: adults-children-newborns
