VFM60 Series Vortex Flowmeter – Compressed Air

Description

Main features:

With extremely high sensitivity, the lower limit of gas flow rate can reach 2 m/s.
Built-in temperature and pressure sensors are available, capable of measuring the temperature and pressure of the medium.
The range ratio far exceeds that of traditional vortex flowmeters, with a wide measurement flow rate range.
The fully isolated electrical structure completely filters out external interference.
Patented dual vortex flow sensor design, with excellent vibration resistance performance.
Wide power supply voltage input range to adapt to various complex power supply environments.
Large-screen liquid crystal dual-line display, with clear and easy-to-read readings. No moving parts, no pressure loss

Application fields:

Measurement of compressed air cubic meter consumption
Monitoring of coal mine gas extraction flow rate
Measurement of natural gas cubic meter flow and consumption
Measurement of fluid temperature and pressure


The built-in pressure and temperature sensors reduce the installation workload while minimizing potential pipeline leakage points, making the use and maintenance safer and more convenient. The embedded gas compression compensation factor calculation program is used for gas trade metering.
