Flow VA 500 - Flow meter for compressed air and gases Special features: Inner diameter adjustable via keypad • Including temperature measurement • RS 485 interface, Modbus-RTU as standard Option: Bi-directional measurement. Blue or green arrows in the display indicate the direction of flow. A meter reading is available for each flow direction. • Integrated display for m³/h and m³ • Applicable from 1/2” to DN 1000 Movable mounting thread G 1/2" • Easy installation under pressure • 4...20 mA analogue output for m³/h or m³/min • Pulse output for m³ or M-Bus (optional) • Inner diameter adjustable by means of keys • Flow meter can be reset • Adjustable by means of keypad on the display: Reference conditions, °C and mbar, 4...20 mA scaling, pulse weight VA 500 flow sensor in basic version: Standard (92.7 m/s), probe length 220 mm, without display Bi-directional measurement - includes 2 x 4…20 mA analogueue outputs and 2x pulse outputs. These do not apply to Ethernet (PoE) and M-Bus DVGW approval for natural gas (maximum pressure 16 bar) High-pressure protection recommended for installation from 10 to 50 bar (for VA 400/500) ISO calibration certificate (5 calibration points) for VA sensors Gas mixture:___ (specify gas mixture when placing order) Special cleaning oil and grease free (e.g. for oxygen applications) LABS and silicone-free version including cleaning oil and grease-free Thermal mass flow sensor Measured medium: Gas types are adjustable over CS service software or CS data logger: Air, nitrogen, argon, helium, CO2, oxygen, vacuum Measuring range: Accuracy: (m.v.: of meas. value) (f.s.: of full scale) Operating temperature: -30...110 °C sensor tube -20...+70 °C housing Operating pressure: -1…50 bar (for pressure > 10 bar - order additional high-pressure protection) Digital output: RS 485 interface, (Modbus-RTU), optional: Ethernet interface PoE, M-Bus Analogue output: Pulse output: 1 pulse per m³ or per litre electrically isolated. Pulse weight can be set on the display. Alternatively, the pulse output can be used as an alarm Polycarbonate (IP 65) Stainless steel, 1.4301 Installation length 220 mm, Ø 10 mm Mounting thread: Mounting position: Additional calibration curve stored in the sensor (can be selected via display) Diameter for volume flow calculation, counter resettable Gas type:___ (specify gas type when placing order) m³/h, m³/min, l/min, l/s, ft/min, cfm, m/s, kg/h, kg/min, g/s, lb/min, lb/h Sensor tube: m³/h, l/min (1000 mbar, 20 °C) in case of compressed air or Nm³/h, Nl/min (1013 mbar, 0 °C) in case of gases Units adjustable via keys at display:

Flow Simple installation and removal under pressure 1) Even under pressure, the flow probe VA 500 is mounted by means of a standard 1/2" ball valve. During mounting and dismounting the safety ring avoids an uncontrolled ejection of the probe which may be caused by the operating pressure. For the mounting into different pipe diameters, VA 500 is available in the following probe lengths: 120, 160, 220, 300, 400 mm. The flow probes are therefore suitable for being mounted into existing pipes with diameters of 1/2" to DN 300 upwards. The exact positioning of the sensor in the middle of the pipe...
