CS Instruments VA 520 | Thermal Mass Flow Meter with Integrated Section | DN 8 to DN 80, 40 bar, -30...80 °C
The VA 520 is an inline thermal mass flow meter with an integrated measuring section, covering DN 8 to DN 80 for compressed air and non-corrosive gases. It is installed permanently at distribution stations, in front of departments or for billing individual users. For cleaning or recalibration the sensor comes out while the section remains in the line, sealed with a cap.
