Water medium ultrasonic flowmeter measurement scale equipment on-line calibration

Abstract: the water medium ultrasonic flowmeter measurement scale equipment calibration to explore online information produced by excellent flow meter, flow meter manufacturer to offer you the quotation. Unified by the metrological management department of the company management. Make sure that the measurement points. More flow meter manufacturers choose model price quote you are welcome to inquire, here is water ultrasonic flowmeter measurement scale equipment calibration to explore article details online. Unified by the metrological management department of the company management. To ensure the measuring point accurately according to the national mandatory standard operation GB17167 & ndash; 2006 the energy-using units energy measuring instruments equipped with the general rules and management requirements and the relevant measurement laws and regulations. As the settlement of the flowmeter, require periodic verification. But does not guarantee that the laws and regulations of the verification period with the accuracy of the meter and the complexity of the medium due to the use situations, many flow meter is not to the verification cycle has been poor. The measurement accuracy is greatly increased. The installation of the portable ultrasonic flowmeter should consider from the following aspects: ( 1) Details about the situation; （ 2) Installation method: ( 3) Choose to install pipe; （ 4) Install distance calculation, determine the probe location; （ 5) Pipe surface treatment; （ 6) Probe installation and wiring. Portable ultrasonic emitter location choice of portable ultrasonic flowmeter required liquid in the pipe must be full package requirement for straight pipe before and after when installation for at least 10 d, 5 d (before meet D for pipe diameter) 。 Upstream or downstream if installed with elbow, tee, throttle valve and damping holes, divergent tube, the choke pieces such as reducing pipe, the length of straight pipe upstream will ask for 30 d, downstream straight pipe generally only need 5 d on the horizontal section, transmitters commonly installed in is on the side (on the side of the tube To avoid the upper sediment at the bottom of the pipe or pipe, gas bubbles signal loss caused by hole) 。 The installation of the transmitter is the key factors that affect the measurement accuracy. Installation generally have Z type, W type, V type 3 kinds. If the installation space ( 25, 406) 1131/1 (between 1 inch ~ 16 inches) Method, appropriate USES V installation; If the installation spacing is less than 5 LMM ( 2 inches) When W method is used to install. If applicable to the methods of V and W installation spacing greater than 406 mm ( 16 inches) Reduce the influence on measurement accuracy. Attenuation of ultrasonic signal is different. Will measure the flow. Liquid level transmitter: the above is all there is in this article, you are welcome to inquire me manufacturer flowmeter selection, quotation, etc.
