VFM55 Vortex Flow Transmitter for Small Pipse Gas Consumption Measurement

VFM55 vortex flow transmitter based on “Karman vortex’ theory, and designed for air, gas and liquid measurement in small pipeline.
Specializes in accurate flow measurement within small pipelines for liquids, gases, and steam. Equipped with dual-sensor anti-vibration technology, temperature and pressure compensation, and a high turndown ratio, it ensures reliable performance even in compact installations across energy, manufacturing, and process control sectors.

Features of VFM55 vortex flow transmitter

Wet/ dry air measurement
DN8 ~ DN25(1/4”~1”) small pipeline measurement
Combines temperature, pressure, flow and standard flow measurement
Bluetooth function option, can read and set on Comate app
Battery power supply and also have 24VDC port
User-friendly operating interface

Bluetooth operating

Parameter & Function setting via Comate bluetooth app
Setting auto crosschecking on PHM system
Flow signal & data analysis
Remote diagnosis

24VDC & Battery power supply for option

VFM55 vortex flow transmitter has lower power consumption, with build-in ER26500 lithum battery, it can ensure long-term battery life. Avoding flow data missed due to power ourages. It also has a 24VDC power supply port.

Anti-vibratin performance

VFM55 vortex flow transmitter have a patent dual-sensor design and is using our latest VPA60 transmitter, which enable it to detect and eliminate vibration signal, and provide with best anti-vibration performance.
