VA 570 with integrated 1 1/4" measuring section - Thermal mass flow sensor for flow measurement
Take advantage of the VA 570 flow meter with integrated 1 1/4" measuring section and optimize your energy efficiency and sustainability strategies. This advanced thermal mass flow sensor allows you to monitor your consumption and analyze leaks efficiently. The VA 570 is ideal for use in distribution stations, upstream of individual departments and for consumer billing purposes.
Advantages of the compact VA 570 flow sensor:
- Precise measurement: The VA 570 measures the mass flow directly and enables the output of the standardized volume flow without the need for additional measurements of pressure and temperature.
- High-quality materials: All wetted parts are made of stainless steel, which meets the highest standards of purity and surface quality.
- Rugged construction: The aluminum housing is specially designed for harsh industrial conditions and is also suitable for outdoor installations.
- Low maintenance: Thanks to its design without moving parts, the VA 570 is particularly easy to maintain.
- Low pressure loss: The sensor reduces pressure loss to a minimum, increasing the efficiency of your systems.
- Safety certificates: The VA 570 can be supplied with ATEX or DVGW certification, which qualifies it for use with various gases such as natural gas, hydrogen and biogas.
- High accuracy: It guarantees precise measurement of both small and large flows with an accuracy of up to ±1% of the measured value.
- Multiple interfaces: The VA 570 has 04...20 mA, pulse and Modbus RTU (RS 485) interfaces as standard, with additional optional interfaces for extended communication options.
- Integrated display: The device provides you with important measured values directly via an integrated display and makes it easy to control and adjust the settings.
- Easy installation: The sensor can be easily installed in the measuring section and, if necessary, easily unscrewed without having to laboriously dismantle the measuring section.
- Comprehensive diagnostics: All relevant measured values and settings can be called up via Modbus RTU, and you can query extensive diagnostic functions both directly on the display and remotely.
- Flexibility: The VA 570 is designed for media temperatures of up to 180 °C (ATEX version up to 120 °C) and can handle pressures of up to 16 bar (special version up to 40 bar).
