The pressure difference is a common physical instrument. It is mostly used to measure the pressure difference between the deep wells and the two points in the pipeline, so it is called the pressure difference meter.It is also a national practical patent. The entire product is made of aluminum. It does not need to inject any liquid in the table. At the same time, the pressure difference also has the function of stress resistance and anti -vibration.Difference.At the same time, the price of the difference between the difference is also very reasonable.
Voltage price

German Dertu micro pressure differential table TESTO510 micro pressure difference meter, differential pressure meter, differential pressure meter, differential pressure meter, differential pressure meterHigh -precision, the price of the pressure difference is 850 yuan, and the 3.TE2000 micro pressure meter micro pressure surface pressure differential voltage differential circular pointer price is 130 yuan.
Bargard meter principle
The reason why the pressure difference can work is because it follows certain physical principles.There are also many ways of physical principles. Here are two of them. One is the law of conservation of quality, and the other is the law of energy conservation.The liquid in the pipeline is full of liquids. When the liquid flows along the pipeline into the curve, the flow rate of the liquid will form a local contraction state due to pressure. At this time, the flow rate will be accelerated and the pressure will be reduced.The pressure difference.From this we can infer that the larger the liquid flow, the greater the pressure difference.Differential pressure meter is an instrument used to measure pressure, so it can also be called pressure meter.In addition to measuring the pressure difference, the pressure difference can also be used to cooperate with the throttling equipment, so that the flow of liquid flow can also be measured.In addition, the pressure difference can also measure the resistance and pressure of liquid levels, pipelines, underground pipelines and facilities.Its use can be described as quite extensive.Of course, there are many types of pressure difference meters. In addition to the simplest liquid column pressure difference (U -shaped tube), the more commonly used pressure differences include circular scales, float pressure differences, and double -wave pattern pressure differences.Measures, unit combination instrumental pressure differences, and so on.The pressure difference is widely used in industrial enterprises, and has a prominent contribution to testing pressure. At the same time, it also plays an important role in measuring fans or wind turbine.Control of valve.
