VA 420

Compressed air and gas consumption counter

Intelligent solution for accurately measuring compressed air and gas consumption

New consumption counterVA420The working principle is the recognized thermal mass measurement principle. During the measurement process, the heating sensor is cooled by the surrounding gas,The degree of cooling directly depends on the quality of the air flowing through it.Therefore, an additional pressure and temperature compensation is unnecessary.

Due to its compact design, it can monitor the compressed air system of all compressors and is suitable for the smallest compressed air pipelines(1/4”...2”).VA400Consuming sensors can be used for larger diameter pipelines (from)DN 50arriveDN300）. In addition to compressed air, other gases such as nitrogen, oxygen, and carbon dioxide can also be measured.

Install compressed air counterVA 420It can be easily and quickly completed. A special advantage is the movable measuring equipment, which can be quickly disassembled and easily used for calibration or cleaning, without the need to dismantle the entire measuring part.

Delete the measurement part of the measuring device without * decomposition

In most cases, compressed air will carry oil, condensate, dirt, and particles, which can cause corrosion of compressed air measuring instruments during this period, leading to measurement errors and even system crashes.

Currently, compressed air counters on the market usually cannot be cleaned,If they get dirty, replace them directly. The integrated counter "measuring device" cannot be removed under air compression Therefore, an expensive bypass pipeline is necessary.

New features:VA 420The design of the "measuring device" makes it easy to remove and can be cleaned with soapy water without having to remove the entire measuring part. During the cleaning period, the pipeline can continue to be used by closing the valve. There is no need for bypass pipelines, positioning pins can enable precise installation of measuring equipment.

stationary use

The online system has the following outputs that can be used for data transmission in building management systems or PLCs:

4...20 mAActual traffic consumption; Total consumption of pulse output (current separation)

Mobile phone usage

The counter, which is rapidly coupled through air compression, can be quickly integrated into the hose of the feed machine. The leakage rate can be determined when the machine is turned off, and the actual consumption can be obtained when the machine is running. The power supply is controlled by the main unit of the power socket. We recommend using a portable DS 300 compressed air analyzer to record data for a longer period of time

Solution for large pipelines

VA 400The consumption sensor is suitable for pipelines with a diameter of2”Go toDN 300The precise design enablesVA400Installed under pressure into pipes of different diameters, the maximum diameter of the pipe can reachDN300.
