Current Output
• Active/Passive selectable
– Active 0/4 to 20 mA, R
– Passive 4 to 20 mA, 30VDC, R
• Full Scale adjustable
• Temperature Coefficient type 0.005 % o.r./°C (o.r. = of reading)
• Time Constant Selectable (0.05 to 100 s)
Data logger function
The device has a data logger function. The measured values can be stored in CSV format on an external
USB storage device (FAT 16/FAT 32). A recording cycle of between 1 and 99999 seconds can be selected.
storage devices with a maximum capacity greater than 2 GB should not be used.
Approx. 130 bytes are needed per recording. The standard supplied USB storage device has a maximum capacity of 1 GB.
The following values are stored:
• Time (dd.mm.yyyy hh:mm:ss)
• Flow
• Sound velocity
• Flow velocity
• Signal strength
• Noise ratio
• Counter 1 to 3
• System status
• 0/4 to 20 mA current input (flow rate and active current value)
Each recording is marked with the tag name and device-specific information, such as the serial
number for example.
Site Manager function
Allows for storage of programmed sites (pipe data, sensor data, fluid data, etc.) on an eternal USB storage
device. Up to 20 sites can be stored.
Switch points for low flow cutoff are selectable.
All circuits for inputs, outputs, and power supply are galvanically isolated from each other.
