Description

Flow meter insertion type- VA 520 – Inline flow meter with integrated measuring section, (R 1/4″ DN 8)
 
Flow meter insertion type- VA 520 application-technological features:
• Digital interfaces such as Modbus-RTU, Ethernet (PoE) and M-Bus enable connection to higher-level systems such as energy man-agement systems, building management systems, PLC,…
• Easy and affordable installation
• Units freely selectable via keys on the display m³/h, m³/min, l/min, l/s, kg/h, kg/min, kg/s, cfm
• Compressed air counter up to 1,999,999,999 m³ can be reset to “zero” via keypad
• Analog output 4…20 mA, pulse output (electrically isolated)
• High measuring accuracy even in the lower measuring range (ideal for leakage measurement)
• Negligibly small loss of pressure
• Calorimetric measuring principle, no additional pressure and temperature measurement necessary, no mechanically moved parts
• Comprehensive diagnostic functions can be read out on the display or remote access via Modbus-RTU such as exceeding max./min values °C, calibration cycle, error codes, serial number. All parameters can be read out and changed via Modbus
 
Flow meter insertion type- VA 520 display shows 2 values at the same time:
• Present flow in m³/h, l/min,…
• Total consumption (counter reading) in m³, l
• Temperature measurement Readout values in the display can be rotated by 180°, e.g. for overhead installation

Flow meter insertion type- VA 520 with a key stroke:
• Reset counter reading
• Select units
• Zero-point adjustment, leak flow volume suppression

Flow meter insertion type- VA 520 options:
Bi-directional measurement.
Blue or green arrows in the display indicate the direction of flow.
A meter reading is available for each flow direction.
