1. What is the minimum flow rate of a mass flowmeter that cannot be less than?
There is no fixed and unified standard for the minimum flow rate of a mass flowmeter, and it needs to be determined based on the specific product type, brand, and model. 1. Example of minimum flow rate for non defective products: The Dutch Bronkhorst gas mass flowmeter ES-103i has a minimum flow rate (controller) of 2 milliliters per minute, which is suitable for gas measurement and control scenarios with medium precision requirements. The quality flow meter of domestic manufacturer Yidu is designed based on the principle of laminar pressure difference. Its standard product has a minimum measurement and control range of 0.5 sccm (0.5 ml/min under standard conditions). According to the conventional range ratio of 100:1, the actual measurable range can be as low as 5 microliters/minute to 500 microliters/minute. 2. The conventional application range of gas mass flow meters. This type of flow meter is mainly targeted at small and micro flow gas scenarios, with a flow coverage range from 0.000001 m ³/hour to 300 m ³/hour, corresponding to pipe diameter specifications ranging from 3mm to 65mm. In practical applications, there is a direct correspondence between the physical structure of the flow meter (such as the diameter of the punching hole) and the flow range. 3. The core principles of equipment selection should be clarified by users first. Based on the minimum flow demand in actual operating conditions, select product models with lower range limits than this value. If the measured flow rate is close to the lower limit of the equipment range for a long time, it will lead to a decrease in measurement accuracy. It is necessary to instal
