We recently acquired a large inventory of overstock items. These items are missing the manufacturer’s original packaging. They may also have minor cosmetic blemishes from storage (See Photos)

The character blocks decode to these exact specifications:

DTFXB Standard: Flow Meter Transmitter Prefix: This is a dedicated liquid flow meter model. It features a built-in 4-20mA output, two open-collector transistor outputs (for rate/signal alarms or totalizing pulses), a 0-1,000Hz rate frequency output, and integrated Modbus RTU RS485 communication protocols.

ZN Enclosure Type: Indicates a NEMA 4 (IP65) rated aluminum enclosure. This design is optimized for rugged wall or pipe mounting in harsh, heavy-duty industrial environments.

DK Power Supply: Configured for low-voltage power. It requires either 10–28V DC input to power the transmitter.

NN Output / Network Options: Explains that the unit relies on its Standard Integrated Inputs/Outputs. It does not include add-on, specialized expansion communication cards (such as BACnet or Modbus RS485 module upgrades).

NA Agency Approvals: Approved for North American regulatory standards. The unit complies with regional UL and CSA safety certificates for specialized or standard plant installations.
