Product catalog summary

Overview: The VX 570 Vortex Flow Sensor is designed for measuring the flow of steam, gases, and liquids. It offers high precision with integrated pressure and temperature compensation, making it suitable for various industrial applications.

Key Benefits:

Measures standard volume flow, operating volume flow, and mass flow.
Operates at high temperatures up to 350°C and pressures up to 63 bar(g).
Compatible with unknown or changing gas compositions and mixed gases.
Constructed with stainless steel for resistance to aggressive media.
Insensitive to vibrations due to reference vibration measurement.
No moving parts, reducing maintenance needs.

Technical Specifications:

Measuring Range: Varies by medium and nominal width, detailed in tables.
Accuracy: Gas/Steam: ±1% to ±2.5% of measured value; Liquids: ±0.75% to ±2% of measured value.
Process Temperature: -40 to +350°C.
Process Pressure: Up to 63 bar(g).
Material: Stainless steel 304 for measuring section; Aluminium for display unit.
Signal Outputs: RS 485 (Modbus-RTU), 3x 4...20 mA, optional Ethernet interface.
Power Supply: 18–36 VDC.
Protection Class: IP67.

Applications:

Measurement of saturated and superheated steam.
Measurement of liquids and mixed gases.
Suitable for corrosive media.

Model Variants:

Basic Models: A1 with integrated sensors, A2 without.
Measured Medium Options: B1 Steam, B2 Liquids, B3 Gas.
Display Options: C1 With display.
Process Connection Types: Wafer type, Flange DIN, Flange ANSI.

Measuring Ranges: Detailed tables provide specific flow ranges for gases, liquids, and steam under various conditions, including temperature and pressure variations.

Ordering Information: The product can be customized using an order code that specifies model type, medium, display, connection type, and other options.
