VorTek M22 Multivariable Vortex Mass Flow Meter for Liquid Gas Steam Measurement
Product Spotlights
Product Overview
The VorTek Instruments Pro-V M22 Multivariable Vortex Flowmeter features a multivariable design that delivers accurate and reliable flow measurements. This multivariable design integrates a high-precision velocity sensor, a platinum resistance temperature sensor, and a solid-state pressure sensor. The M22 provides measurement data for volumetric flow, mass flow, temperature, pressure, density, and energy (BTU) with just a single unit. Compared to installing multiple instruments to obtain the same process measurement data, this significantly reduces complexity, equipment costs, and installation costs.
The M22 flowmeter offers an industry-leading range of communication and power supply options. In addition to traditional communication methods such as analog output signals, the flowmeter also supports advanced serial communication options such as BACnet/IP and Modbus TCP/IP. The M22 is the only vortex flowmeter on the market with Power over Ethernet (PoE) capability. The PoE feature transmits both power and data simultaneously over a single Ethernet cable, simplifying the installation process and reducing installation costs.

Product Applications
Steam Measurement
The M22 is an ideal choice for steam measurement, accurately measuring the mass flow of both saturated and superheated steam. It supports dual compensation for temperature and pressure to ensure measurement accuracy.
Gas Measurement
Suitable for measuring gases such as natural gas, compressed air, and nitrogen, with strong resistance to interference and high stability.
Liquid Measurement
Capable of measuring liquids such as water and oil, with a wide turndown ratio to accommodate various flow requirements.
Harsh Operating Conditions
The M22 maintains stable performance even in high-pressure, high-temperature, or contaminated environments, reducing maintenance costs.
