What does the 1.5L/min flowmeter have an accuracy level of 2.5 mean?
The 5L/min flowmeter has an accuracy level of 2.5, which refers to the maximum allowable error of the flowmeter when measuring a flow rate of 5 liters per minute, which is ± 2.5% of the measured value. 1. The meaning of accuracy level: The accuracy level of a flowmeter is a standardized concept used to indicate its maximum allowable measurement error.
Level 2.5 means that at any measurement point, the indication error of the flowmeter will not exceed ± 2.5% of its range. For the 5L/min you mentioned, this usually refers to the specific measurement point or measurement range of the flowmeter, rather than its full range. 2. Specific calculation and interpretation: For a flowmeter with a range containing 5L/min, the error calculation method at that point is as follows: * Maximum allowable error=5 L/min × ± 2.5%=± 0.125 L/min. This means that when the actual flow rate of Siheng is 5L/min, the displayed value of the flowmeter should be between 4.875 L/min and 5.125 L/min
3. Industry application and standard accuracy level 2.5 belong to the conventional level in industrial applications, commonly used in process monitoring, general measurement or cost sensitive scenarios with low accuracy requirements. It complies with national machinery industry standards (such as JB/T 9246-1999) and international standards (such as ISO 4064). It is quite common in fields such as water treatment, irrigation, and chemical batching. If used for trade settlement or precision experiments, it is necessary to choose a higher precision flow clearing meter (such as 0.5 or 1.0 level)

2. What is the unit of cmf
1. cmf is the Coriolis Mass Flow Meter (CMF), and the Coriolis Mass Flow Meter is a novel instrument for directly and precisely measuring fluid mass flow. The main structure uses two U-shaped tubes arranged side by side, causing the bent parts of the two tubes to vibrate slightly towards each other. The straight tubes on both sides will vibrate accordingly, that is, they will approach or open at the same time, that is, the vibration of the two tubes is synchronous and symmetrical.
2、 If fluid is introduced into the pipe while synchronously vibrating, causing it to flow forward along the pipe, the pipe will force the fluid to vibrate up and down together with it. In order to resist this forced vibration, the fluid will give the tube a reaction force perpendicular to its flow direction, which is called the Coriolis effect force. Under this force, the vibration of the tube is not synchronized, and there will be a difference in the timing of vibration between the inlet and outlet sections of the tube, which is called the phase time difference. This difference is directly proportional to the mass flow rate of the fluid flowing through the pipe. If the
