Therefore, it is the most popular type of ultrasonic meter. Ultrasonic meters can also use multiple paths to achieve results in a number of custody transfer applications. An ultrasonic flow meter uses transmitters and receivers of acoustic energy and for this purpose piezoelectric crystals are used. So care must be taken to ensure that this pulse rate is … The maximum output frequency is 1000 Hz. Find helpful customer reviews and review ratings for SonicSniffer: Ultrasonic Frequency Meter (1.00 – 50.00 kHz) at Amazon.com. More specifically, the meters measure the velocity of acoustically conductive water as it flows through the meters. A flow meter ultrasonically measures fluid velocity in a pipe and ultrasonically transmits fluid flow data along the pipe. While ultrasonic frequency selection at 25kHz are used to clean heavy and large parts or those with highly-bonded contaminants, some of their negative properties can be reduced by adding a higher frequency to the system such as in our CROSSFIRE Multiple Frequency Ultrasonic System. The SonicSniffer determines the working frequency of the acoustic set by analyzing the sound emitted by the equipment … Ultrasonic meters provide a wide array of diagnostics that can be viewed with software These diagnostics are sometimes not ... • I/O Wizard for checking and validating all frequency and digital outputs (DO) are working properly with the … There are minimum meter Ultrasonic meters use the frequency of 1 MHz, which is not even close to the frequency for acoustic noise. These flow meters are used for flow measurement applicatons of 0.1 to 30 FPS. Electrical energy is applied to the crystal and it is applied in the form of a short burst of high frequency and this would cause the crystal to vibrate. The signal chain below is best suited for applications requiring higher performance, especially those with multiple pairs of trans-ducers. How Ultrasonic Technology Works. Ultrasonic distance meter works on a principle similar to radar or sonar which evaluates attribution of a target by interpreting the echoes from radio or sound waves respectively. No pipe cuts Easy to configure. Ultrasonic flow meters are inferential meters that use ultrasonic technology to measure the velocity of an acoustically conductive liquid moving through it.
