Issues regarding the metering of compressed air and compressed nitrogen
Thread Content
Hello everyone, I have a question I’d like to ask you. General chemical plants or workshops require compressed air and compressed nitrogen, and the metering departments are responsible for taking readings in order to calculate costs. So, do people generally use domestic or foreign-brand watches? What do organizations usually choose – standard models or custom ones? Should the watch come equipped with temperature and pressure sensors built-in, or should those functions be handled by a DCS system? Generally, a workshop has around 120 valves. How much gas does a well-sealed gas supply pipeline consume per hour? I’d appreciate it if everyone could provide an answer. Thank you

It involves no trade measurement or accounting; domestically produced products are generally sufficient. If pressure and temperature have little impact, a cubic meter unit can be used; if there is an impact, it is recommended to use standard cubic meters. As for temperature and pressure compensation, you need to decide for yourself. It’s convenient to use units that include built-in temperature and pressure compensation, but they are more expensive. Check the relevant standards to determine the appropriate gas consumption
The accuracy of foreign products is higher; domestic ones probably need to be calibrated every 2 or 3 years
