In the winter, as the temperature drops, it frequently appears that the ambient temperature is too low for phenomena like freezing, solidifying, crystallization, and other phenomena when the measured medium is transferred to the transmitter through the measurement line. This is because the ambient temperature is too low and outside the instrument's normal working temperature range, which has an impact on the instrument's measurement display accuracy. Additionally, since the measurement medium is primarily liquid and is affected by low temperatures, measurement errors are more prone to occur. Serious cases may result in poisoning, fire, explosion, and other safety mishaps.

The general rule of choosing a flowmeter is, first and foremost, to thoroughly understand the structural principles of various flowmeters, fluid properties, and other aspects of knowledge, but also according to the specific circumstances of the site and look at the surrounding environmental conditions. This is done in order to ensure the accuracy of the flowmeter, stability at the same time, its widest range, and the minimum lower limit. Moreover, there are other issues. Let's keep up with ATO.com to find out more!

1. First, speak with the on-duty process operator.
2. Enter the building site after gathering your tools and wearing the appropriate safety gear.
3. Before the flow meter is put to use, confirm with the process operator that the flow meter flange is tight, the pressure gauge installation is complete, and the filter and pipeline venting are both closed. This will ensure that all venting points are closed.
4. To avoid fluid impact measurement parts being damaged by the incoming shaft sealing mechanism connection shaft damage, instruct the process operator to first open the flow meter export side valve and then then slowly open the inlet valve gate.
5. After putting the flow meter into normal operation, check to see if the instantaneous flow rate, pipeline pressure, and temperature all match the values on the flow meter nameplate. Before leaving the site, make sure the work is finished and that there are no leaks at the sealing locations.

Exports are rising, and China has established itself as a major industrial hub for electrical and technological goods. Along with consumer product safety, manufacturers are always enhancing product safety requirements in accordance with pertinent international laws and regulations. Additionally, before a product leaves the plant, it is thoroughly inspected for safety by the maker. The product's electrical function's safety, or perhaps its resistance to electric shock, is also a crucial component of the inspection.

The product's planning, construction, and insulation materials all have matching requirements or specifications that may be understood in order to comprehend how well the product insulates. Manufacturers typically employ a variety of inspection and testing techniques. However, a test is required for electrical products, and the electrical strength test can reveal whether the product performs well overall in terms of insulation.

Many different withstand voltage testers are available on the market right now. Manufacturers must increasingly prioritize cost-cutting in order to purchase practical withstand voltage testers for investments and internal purposes.

The wind turbine, borrowed from jet engine technology, overcomes a fundamental drawback of conventional wind turbines. A wind turbine's blades are surrounded by a shield that directs air through them and speeds them up, increasing the amount of electricity produced. A wind turbine is a turbine powered by wind energy. To make a wind turbine last, we need to learn how to maintain it. In this article, we describe the maintenance of wind turbines in chronological order.

A magnetic stirrer is a device that forces liquid and gas media to convect and mix uniformly. The type, size, speed, power and other parameters of the agitator have an important impact on the effect of media stirring and mixing. Different stirring processes need to be realized by the operation of different stirring devices. When selecting the type, first of all, the purpose and requirements of the stirring operation should be based on the process. The following is an introduction that how to troubleshoot magnetic stirrers.

Magnetic stirrers have become a wide variety of low-cost laboratory routine equipment, which enables us to have the ability to choose the magnetic stirrer that we need. Faced with many types of magnetic stirrers with different prices on the market, how should we choose? For applications that only require stirring at room temperature, choose a simple magnetic stirrer with only stirring function. For applications that require stirring and heating at the same time, and the temperature requirements are not very strict, a standard heating magnetic stirrer should be selected.

The magnetic float level sensor is suitable for liquid level or interface measurement in open or closed pressure vessels. It is a float switch that uses a magnetic float as a sensing element, and reflects the measured liquid level or interface through the coupling between the magnetic float and the magnetic body in the display color bar. However, how to maintain a magnetic float level switch in winter?

Every time we use the gloss meter, we must first calibrate the gloss meter. The purpose of calibration is to eliminate the influence of changes in the intensity of the light source and environmental changes each time the machine is turned on. This step of calibration is very important. If the calibration is not done well, the measurement will be greatly affected. Therefore, during the calibration process, it is necessary to ensure that the bottom surface of the gloss meter and the calibration plate are in very close contact. So how to calibrate gloss meter?

Gloss meter, as known as gloss tester, is used in gloss measurement for paint, marble, ceramic, plastic, metal, etc. Gloss meter is widely used in chemical raw materials, paint manufacturing, aerospace industry, automobile industry, car maintenance, floor polishing, electronics, electrical appliances, IT communications and other industries. But how to choose a gloss meter?

Lime glaze is a commonly used glaze in the production process of traditional lime glaze ceramic. Due to the difference in raw materials and calcination process, the appearance and color of lime glaze will be different. In order to verify the surface gloss of lime glaze, a gloss meter can be used to measure. The lime glaze uses calcium oxide as the flux, and the glaze whose molecular number of calcium oxide should account for more than half is the lime glaze.
