The IC card prepaid industrial gas meter is a commercial and industrial Diaphragm gas meter that incorporates the best of domestic and international products. It has been developed with the innovative spirit and experience of Kinhil meters for over 20 years. These gas meters are suitable for the metering of non-corrosive gases in restaurants, canteens, and factories. These gases include manufactured gas, natural gas, methane, LPG, and other non-corrosive gases that are not sensitive to impurities. IC card prepaid industrial gas meters comply with the GB/T6968-1997 national standard (Class B) and the OIML-R3 standard of the International Organization of Legal Metrology. Next, let's analyze the reasons why Diaphragm gas meters become faster and slower.
Here is the content list:
The calorific value of the gas used by the user before and after the changeover is different.
Analysis of the metering characteristics of the Diaphragm gas meter itself.
First of all, the Diaphragm gas meter is a gas flow measurement instrument that can be used to measure different calorific values of gas. However, if the calorific value of the gas is different before and after the gas is measured, this can give the impression that the gas is going faster or slower. For example, before the replacement of natural gas in a district, residents used a regional piped gas source of liquefied petroleum gas. After the switch to natural gas, some attentive residents noticed that the diaphragm civil gas meter was running much faster than before. This is because the heat load of natural gas, oil gas, and LPG appliances is the same, and the same amount of heat is required to boil a pot of water. However, the calorific value of these three types of gas is 9,600 calories per cubic meter, 6,500 calories per cubic meter, and 26,000 calories per cubic meter. Therefore, the amount of gas used to boil the same kettle of water with each of them is different. The amount used when burning natural gas is about 1/3 less than when burning oil-based gas, and more than double the amount used when burning LPG. This is reflected in the speed of the Diaphragm gas meter of a customer who has switched to natural gas for crude oil or LPG, and a careful customer will notice that the meter is turning slower or faster. This is mainly due to the different calorific values of the gas used before and after the changeover, which is normal.
Most Diaphragm gas meters with good manufacturing processes are normal, while most Diaphragm gas meters with poor manufacturing processes are slower. The slowdown may be in the order of tens of percentage points or it may not go at all. This is because a good manufacturing process nature gas meter transmission components resistant to wear and tear, the internal structure is stable, the operation of small wobble, the internal gas valve uniform wear, over time the gas tightness will become better and better, Diaphragm gas meter measurement accuracy is stable and accurate. Secondly, if the gas is not very clean, which leads to scaling in the metering chamber, it may make the Diaphragm gas meter faster. A poorly crafted Diaphragm gas meter valve will be biased towards wear and tear, resulting in poorer and poorer gas tightness, the internal skin may break and the gears may slip. Or, if the valve is not self-lubricating enough, the resistance becomes greater over time, causing the meter to 'slow down.
