1. How to inquire about the standard specifications and models of flow meters
To inquire about the standard specifications and models of flow meters, accurate information can be quickly obtained through three core paths: disassembling the meaning of the model, viewing the equipment nameplate, and searching for industry standards. 1. Disassemble the literal meaning of the model and quickly identify the basic parameters. The flowmeter model is generally composed of a combination of letters and numbers, and the naming rules of different manufacturers may vary slightly. The general reference logic is as follows: - prefix letter: represents the flowmeter type and medium, for example, LW is a turbine flowmeter LU is a vortex flowmeter, and LD is an electromagnetic flowmeter. G represents gas and Y represents liquid. The middle number is usually the nominal diameter DN value, measured in millimeters. For example, 100 represents DN100, corresponding to a pipeline inner diameter of 100mm. The suffix parameters will indicate information such as working pressure, material, and accuracy level. For example, 2.5MPa represents the rated working pressure of 2.5 megapascals, and B represents brass material. 2. Check the equipment nameplate to obtain complete specifications. The nameplate of a regular flowmeter will indicate all core specifications and hole grid information, with a focus on the following 10 items.
1. Flow meter type: such as turbine, electromagnetic, ultrasonic, etc. Working principle 2 Measurement medium: Suitable for specific fluid types such as water, oil, natural gas, etc Nominal diameter: The standard annotation is DN+number, corresponding to the pipeline installation size of 4 Accuracy level: The sm
1. Domestic standards: Log in to the National Standards Full text Open System and the official website of the China National Institute of Standardization, search for the keyword "flow meter" to query the corresponding national and industry standards. 2 Enterprise standard: Contact the flowmeter manufacturer or supplier directly and request the corresponding products execution standard document 3 International standards: Search for the corresponding international common flow meter standards through the ISO online standard platform and the American ANSI standard website.
2. Selection of commonly used flow meters for sewage flow monitoring
The commonly used flow meters for sewage flow monitoring mainly include electromagnetic flow meters and acoustic Doppler flow meters. The following is a detailed introduction to these two types of flow meters: The b
