CS INSTRUMENTS VA520 Consumption meter with integrated 1/4", DN 8 measuring section 1.4301
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
Inline flow meter - measuring section DN 8, 1.4301
The CS Instruments VA 520 is a thermal inline flow meter with integrated measuring section made of stainless steel 1.4301. This version with measuring section DN 8 is installed directly in the pipe - no insertion sensor, no additional measuring chamber. The VA 520 is DVGW-tested and therefore also approved for billing purposes. Display, totalizer, 4-20 mA, pulse and RS 485 (Modbus-RTU) are on board as standard. All gas types: compressed air, N₂, O₂, CO₂, argon and many more.
Application areas
The VA 520 is particularly suitable for standard-compliant consumption recording at compressor stations, in energy balancing and in compressed air monitoring in accordance with ISO 50001 Screen recorder the measurement data is recorded and evaluated centrally. Accessories such as connection cables can also be found at FILCOM.
