How to choose a large diameter ultrasonic flowmeter

Ultrasonic flowmeter (ultrasonic water meter) uses the electronic principle to measure the flow meter. Although it has its own verification procedure, it has a common use management mode because it is metered with the tap water industry, so its performance requirements, measurement accuracy, verification cycle, etc. It has become more standardized in the list of cold water meters. Since then, the use of large-caliber ultrasonic flow meters has normative documents in the water industry.

Ultrasonic flowmeter (ultrasonic water meter) Because the measurement principle is different from electromagnetic water meter, its accuracy is different, how to choose an ultrasonic flowmeter with superior performance and precision:

1. The user flow range is used to determine the type, diameter, temperature, medium, etc. of the ultrasonic flowmeter, especially considering the common flow rate and the starting flow rate. The purpose is to ensure the water supply quantity, accurately measure and reduce the leakage rate. When using the water meter, the user's water meter Commonly used traffic generally cannot exceed the common flow value specified by the product.
2. Different flow rates determine the flowmeter of that diameter to meet the measurement range.
3, the user environment is different, come first.
4. Also consider the working pressure, the structure of the flow certificate, the form of the converter (whether bidirectional flow, current, pulse, communication interface, data storage) and the length of the connecting cable.
5. The performance and accuracy of the ultrasonic flowmeter are selected.
6, users can learn more about the peers who are already using the ultrasonic flowmeter, to see the effect of their use, the accuracy of the measurement.

At present, industrial flow measurement generally has problems of large diameter, large flow, small diameter, small flow, high temperature liquid, and gas measurement. This is because the general flowmeter will bring manufacturing and transportation with the increase of the measuring pipe diameter. The difficulty of the above, the advantages of increased cost, increased energy loss, and inconvenient installation, ultrasonic flowmeters can be avoided. The German FLEXIM ultrasonic flowmeter measures diameters from 6mm to 6500 mm, from a few meters wide open channels, culverts to 500m wide rivers.

Large-caliber flow meter management is the key to the water supply industry. Through advanced monitoring equipment and means, the metering accuracy of flow meters is improved, and the apparent leakage is minimized. The management of large-caliber metering is a long-term work. Relevant personnel are required to regularly collect, track, and analyze the flow data, and handle the applicability and accuracy of the flow meter.

Double Packed Yellow Waxy Corn Cob

The most common waxy and sweet corn market, waxy corn nutrient content is higher than ordinary corn, contains 70-75% starch (and almost all amylose), more than 10% protein, 4-5% fat and 2% multivitamin, has more grain, VA, VB1, VB2 than rice protein, fat and VB2 highest content. Yellow corn also contains carotenoids like rice and wheat. The molecular weight of glutinous corn starch is more than 10 times smaller than that of ordinary corn. The starch makes glutinous rice sticky and soft, which is softer than that of ordinary hard corn. It has more than 20 percent more digestibility than regular corn and is suitable for people with irregular teeth. At the same time, the amylose (a polysaccharide) content is very high, not suitable for diabetics.

Waxy corn is also called sticky corn. The grain has a coarse, waxy endosperm that resembles a glossy, transparent grain, such as a hard, dented corn. Its chemical and physical properties are controlled by a recessive gene located on chromosome 9. 100% of the starch in the endosperm is amylose.
