CS INSTRUMENTS VA 525 Compact inline flow sensor G 3/4"
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
Compact inline flow sensor - G 3/4"
The CS Instruments VA 525 is a compact thermal inline flow sensor with G 3/4" connection. Specially developed for smaller pipes up to DN 50, it offers the same measuring principle and the same accuracy as the larger VA models - only in a significantly smaller housing. Display, totalizer, 4-20 mA, pulse and RS 485 (Modbus-RTU) are standard. For compressed air and non-corrosive gases.
Application areas
The VA 525 is ideal for measuring consumption on individual machines, in bypass lines or compact compressed air distributions. In combination with a Screen recorder creates a seamless compressed air monitoring system. Accessories such as connection cables can also be found at FILCOM.
