Aircones can be used to measure supply or return airflows depending on how the RVA801 or RVA501 is attached to them. Arrow indicators on the vane head provide an indication of which way the airflow should be passing through the vane anemometer when attached to an Aircone...
3. High measurement accuracy and good repeatability. The disadvantage of the anemometer is that the probe has a certain interference with the flow field and is easy to break. 4. In addition to measuring the average speed, it can also measure the pulsation value and turbulent amount; in additi...
Press "Set" on the main interface to enter the menu, select "Running parameters" through the arrow keys, and then press "Set" to enter the editing interface. After each parameter is modified, it will automatically switch to the next parameter. If the working group is set to this group, ...

Measure the outdoor air temperature entering the condenser from top to bottom of the coil outside of line of site of the sun and obtain an average condenser entering air temperature. Measure the liquid line temperature with an accurate clamp probe thermometer. Determine the temperature difference ...
It is my hope that understanding how ultrasonics measure wind speed will elucidate other approaches to measuring physical quantities.Presently, ultrasonic anemometers find widespread application in diverse fields, including meteorological monitoring, environmental protection, and modern agriculture—all of which...

When considering and comparing flow meter accuracy, it is important to be aware of both ‘linearity’’; i.e., the flow meter’s ability to accurately measure over the complete turndown ratio, and ‘repeatability’, the ability to remain accurate over a number of cycles. This is another ...
But if we measure installed capacity per capita, we get this very different chart. Now European countries such as Denmark, Sweden, Ireland, and Germany lead the pack, the United States is 13th, the UK isn't much better, China manages only 16th place, and India (not even on the chart)...
The advantages of ultra-clean worktable are easy to operate, comfortable, efficient, short preparation time, and basically ready to use. This is a general type of local purification equipment. The air flow is in the form of vertical laminar flow and horizontal laminar flow. It can create a ...
