Flow VA 570 - Inline flow meter Version with pipe thread R thread or NPT thread Flange version VA 570 is supplied with an integrated measuring section. The measuring sections are available in flanged version or with R resp. NPT thread. A special feature is the removable measuring head. So the measuring unit can be removed easily and quickly for calibration or cleaning purposes without having to dismount the measuring section intricately. During this period the measuring section is sealed by a closing cap (accessory). The screwing with a centring device is designed such that the sensor is positioned accurately in the centre when screwing it into the measuring section; furthermore, it enables an exact positioning in the flow direction. This eliminates unnecessary measuring faults. Approvals: II 2 G Ex db IIC T4 Gb II 2 D Ex tb IIIC T90 °C Db Special measurement technology features: • 4 values on the display: Flow, total consumption, velocity, temperature. Units freely adjustable • All measured values, settings such as gas type, inner diameter, serial number and so on can be accessed via Modbus-RTU The sensor can be removed and cleaned • Comprehensive diagnostic functions readable on the display or remote access via Modbus such as calibration cycle, error codes, serial number • Notification in case of exceeding the calibration cycle • Standard version accuracy 1.5% of m.v. ± 0.3% of f.s. • Precision version accuracy 1.0% of m.v. ± 0.3% of f.s • Measuring span of 1 : 1000 (0.1 up to 224 m/s) • Configuration and diagnosis via display, hand-held device PI 500, PC service software on-site • Gas type (air, nitrogen, oxygen, argon and so on) freely adjustable via PC service software or external device DS 400, DS 500, PI 500 Special mechanical features: • Robust impact-proof aluminium die cast housing for the outdoor area IP 67 • All wetted parts made from stainless steel 1.4571 • On request with DVGW approval for natural gas (up to 16 bar) • Pressure range up to 16 bar, special version up to 40 bar • Temperature range up to 180 °C • Reference conditions °C and mbar/hPa freely adjustable • No moveable parts, no wear • Zero-point adjustment, leak flow volume suppression • Sensor tip very robust, easy to clean • Pressure loss negligible • Housing rotatable, display rot
