Ultrasonic flow meter scale measures to eliminate or reduce the noise influence

Abstract: ultrasonic flowmeter scale measures to eliminate or reduce the noise influence information produced by excellent flow meter, flow meter manufacturer to offer you the quotation. Under the premise of ultrasonic flowmeter in fixed installation conditions, improve the ability of signal processing and diagnosis flow meter itself, can effectively reduce the noise. Under normal circumstances, the measuring accuracy of flow meter is very important. In the case of precision can't guarantee, should be. More flow meter manufacturers choose model price quote you are welcome to inquire, here is a ultrasonic flowmeter scale measures to eliminate or reduce the noise influence article details. Under the premise of ultrasonic flowmeter in fixed installation conditions, improve the ability of signal processing and diagnosis flow meter itself, can effectively reduce the noise. Under normal circumstances, the measuring accuracy of flow meter is very important. In does not guarantee the accuracy, a noise control valve flow meter measurement, will inevitably produce incorrect results. So, to improve the flow meter for the acoustic pulse recognition and detection, improve the filtering ability of signal at the same time, can improve the accuracy of measurement. To reduce the noise interference, appropriate upstream of the flow meter installed in the regulator, the benefits are high pressure, strong signal, noise amplification. Extended meter straight pipe upstream and downstream, as well as between the meter and noise isolation equipment installed will abate noise. But the length of straight pipe may require many times the pipe diameter to reduce noise, so the installation of isolation equipment more convenient and effective. Experimental results show that the filter, heat exchanger, and turbine equipment are good equipment and reduce the noise. Ultrasonic flowmeter bend, blind tee can reduce noise, zui good method is to install blind tee, noise is reflected back after fluid through the blind tee. With two valves to share the pressure drop method can also reduce the generation of noise, but this method often cost is higher. Ultrasonic de-noising, the noise reduction effect is remarkable. Is to use a single de-noising and the flow meter of the same wavelength complex small reflective equipment, foam or a viscous and elastic, absorbing some equipment achieves the goal of eliminating noise. Tests show that this approach can reduce 30% of the noise. De-noising can be directly installed on the downstream side of the flowmeter, flange connection, will not affect the accuracy of flowmeter. Ultrasonic de-noising is usually the clogging and certain pressure drop, so will lose some advantages. But in some cases, such as regulating valve larger pressure drop compared to cause noise, de-noising, the pressure drop is negligible. Ultrasonic flowmeter in the case of a limited space such as offshore platform can be applied to denoising, reduce noise. Above is all there is in this article, you are welcome to inquire me manufacturer flowmeter selection, quotation, etc.
