What does the number after the flowmeter ft represent? In the field of flow meters, FT usually stands for "Flow Transmitter". Model or series identification: Many manufacturers assign specific numbers or alphanumeric combinations as identification for different flowmeter product series. These numbers may be used to distinguish different technical specifications, measurement ranges, materials, or functional characteristics. Measurement range or range: In some cases, the number after FT may directly represent the measurement range or range of the flowmeter. For example, FT-100 may indicate that the maximum flow rate that the flowmeter can measure is 100 units. Serial number or production batch: In some cases, the number after FT may also be used as part of the serial number or production batch number for manufacturers to track the production, testing, and delivery process of the product. Special functions or configurations: In certain specific applications, the number after FT may also represent special functions or configuration options of the flow meter. These features may include remote communication interfaces, specific signal processing algorithms, explosion-proof design, or other performance enhancing features. 2. In the process flow diagram with control points, the symbol representing the electromagnetic flowmeter
In the process flow diagram with control points (P&ID), the standard symbol for the electromagnetic flowmeter consists of "graphic+letter code" and must comply with specifications such as GB/T 2625-2008.
. 1. The graphic symbols that make up an electromagnetic flowmeter usually include three core parts: • Measuring element: The main body is a circular symbol with a horizontal line in
2. Letter code specifications for instrument tag numbers use a combination of "letters+numbers": • Basic code FE: The letter "F" represents flow rate, and "E" represents measuring element, such as FE-101; • Cumulative function FT: If it also has flow accumulation function, use "T" (transmitter transmitter) instead, such as FT-102; • Additional identification: letter combinations can be expanded according to requirements, such as FIQ indicating flow indicator with cumulative function
3. Practical application example: In a chemical P&ID drawing, the circular symbol next to the pipeline has a horizontal line inside, marked FE-301, representing the electromagnetic flowmeter installed at that location with the number 301. The symbol is connected to the pipeline by a solid line, with both ends of the horizontal line pointing in the direction of fluid flow. If FT-402 is labeled next to the same symbol, it indicates that this is a flowmeter transmission device that supports remote data transmission. 4. Differences in labeling indicate that some design institutes may adjust the angle of the horizontal line (such as diagonal lines) or overlay boxes, but the FE/FT letter code is always used as the core identifier.
