CS INSTRUMENTS VA 570 Flow/consumption sensor, with integrated DN 25 measuring section
As a leading manufacturer of compressed air measurement technology, CS INSTRUMENTS stands for highest quality and innovation. "Made in Germany" is our practice - development, production, and calibration take place exclusively in Germany
Flow and consumption sensor - DN 25 measuring section
The CS Instruments VA 570 is a thermal flow sensor with integrated DN 25 measuring section. It records volume flow, consumption and temperature in compressed air and gases. Display, totalizer, 4-20 mA, pulse and RS 485 (Modbus-RTU) are integrated as standard. Measuring dynamics up to 1:1000, bidirectional measurement possible.
Application areas
The VA 570 is suitable for recording consumption on compressors, distributors and individual production lines. In conjunction with a Screen recorder creates a seamless compressed air monitoring system. Accessories can also be found at FILCOM.
