Which abbreviation is used for Flow Transmitter?

• A. FT
• B. TE
• C. TV
• D. FV

Answer: (A)

In instrumentation tagging, abbreviations combine the measured variable with the instrument type. For flow, when the device not only senses flow but also outputs a standardized signal to the control system, it’s called a Flow Transmitter. The common shorthand for that combination is FT, where F stands for Flow and T stands for Transmitter. This distinguishes it from a simple flow sensor or meter, and from other instrument types that use different letters (for example, temperature-related devices or valves).

So FT is the best fit because it clearly communicates both the measured quantity (Flow) and the function of the device (Transmitter). The other abbreviations are typically associated with different instrument types (like temperature-related devices or valves) and don’t denote a Flow Transmitter.
