1. Structure of Insertion Ultrasonic Flow Meter Probe
The structure of insertion ultrasonic flow meter probe is relatively complicated and detailed, mainly composed of the following parts. 1. Piezoelectric element: This is the core component of the probe, usually made of piezoelectric ceramic material. It can achieve the mutual conversion between electrical energy and ultrasonic mechanical energy. When emitting ultrasonic waves, convert electrical signals into ultrasonic vibrations; When receiving cluster search ultrasonic waves, the ultrasonic vibration is converted into electrical signals to complete the transmission and reception of ultrasonic waves. 2. Protective film: located at the front end of the probe, it plays a role in protecting the piezoelectric element. It can prevent the piezoelectric element from directly contacting the measured fluid, avoiding the erosion, corrosion, and wear of the fluid, thereby extending the service life of the probe, and ensuring that ultrasonic waves can smoothly pass through and enter the measured medium. 3. Acoustic wedge: generally installed in front of the piezoelectric element, its function is to change the propagation direction and characteristics of ultrasonic waves, so that ultrasonic waves can enter the measured fluid at an appropriate angle, improve the accuracy and stability of measurement, ensure effective propagation and accurate reflection of ultrasonic waves in the fluid. four Shell: As the overall support structure of the probe infiltration calendar, it not only protects the internal components, but also has good sealing performance, which can prevent external impurities such as moisture and dust from entering, ensuring the normal operation of the probe in
2. Ultrasonic flowmeter debugging steps
Ultrasonic flowmeter debugging operation process: operating environment training: 1 ultrasonic flowmeter, etc.
1、 Press the MENU key and then press the 55 key to display the current loop output mode selection interface.
2、 Press the arrow keys to select the 4-20mA output mode, and press the ENT key to confirm.
3、 When the shear head down button is pressed to set the flow rate to 4mA, the output value of the flow rate is 0.
4、 Press the arrow key again to set the output flow value to the upper limit of 20mA.
5、 After setting up, press the ENT key, then press the arrow key to view the current output value according to the manual. Press the MENU key and 00 to return to the main interface.
3. Installation methods of ultrasonic flowmeter
There are three main installation methods for ultrasonic flowmeter: external clamp type, insertion type, and pipe section type.
. The external clamp type ultrasonic flowmeter is a non-contact instrument suitable for flow measurement of high-pressure pipelines, strong corrosive, non-conductive, radioactive, and flammable and explosive fluid media. Potato chips are easy to install and do not require early rock cutting or pipeline breakage. Magnetic sensors are directly attached to the outer wall of the pipeline and fixed with professional fixtures to ensure non-destructive installation. The cost of external clamp ultrasonic flowmeter is relatively low, and the protection level of the sensor after wiring can reach IP68, which is suitable for harsh environments. The insertion type ultrasonic flowmeter requires drilling and welding sensor bases on the pipeline du
