The FA80M series vortex flowmeter is a widely used flow instrument that can be used for the measurement, measurement, and control of most gases, liquids, and steam. It has a simple structure, no moving parts, and high stability and reliability. The FA80M/FA80T series uses an optimized design scheme, has high universality and interchangeability, and significantly improves the reliability index of the whole machine.
This manual describes the FA80M/FA80T series vortex flow meters, their operating principle based on vortex shedding, and the relationship between vortex frequency and flow velocity. It explains how the sensor output (0‑10 Vpp for FA80M, 4‑20 mA for FA80T) is proportional to the measured flow.
The document also covers installation options (integrated or split type, explosion‑proof classifications), compatible pipe sizes (DN10‑DN600), supply voltages (DC12 V or DC24 V), material choices (1Cr18Ni9Ti stainless steel and alternatives), pressure ratings (PN16‑PN40), and temperature limits (-40 °C to 300 °C). Technical tables provide detailed fluid property data and calibration information. This manual is written in Chinese.

The FA80M provides a 0‑10 Vpp signal that is proportional to the measured flow.
Both meters can be powered from either DC12 V or DC24 V sources.
The meters are available for nominal diameters from DN10 up to DN600.
The standard sensor body is made of 1Cr18Ni9Ti stainless steel.
