Application-technological features of the flow meters VA 520

Diggital interfaces such as Modbus-RTU, Ethernet (PoE) and M-Bus enable agement systems, building managment 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, pluse 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
