Connectivity protocols

One serial RS-232/RS-485 port (115 kbps baud rate) (Modbus RTU/ASCII)

•

(1) Serial Port A 
(RS-232/RS-485 Full Duplex/RS-485 Half Duplex)

One Ethernet Port (TCP/IP) 100 Base 

•

Up to 10 Mbps (internal connection) 100Mbps (external connection)

•

Modbus TCP, TCP/IP

Device compatibility

Daniel Ultrasonic flow meters are compatible with nearly every commercially available flow 
computer.  Examples: FloBoss 103, FloBoss S600 flow computer,  ROC 107, 

Digital Input(s)
(Selectable)

(1) Single polarity 

—

Four pulse configurations available

Analog Input(s)

(2) 4-20 mA

•

AI-1 Temperature

•

AI-2 Pressure

Note:  The analog-to-digital conversion accuracy is within ±0.05% of full scale over the operating 

temperature range.

Note:   AI-1 and AI-2 are electronically isolated and operate in sink mode. The input contains a series 

resistance so HART® Communicators can be connected to configure sensors.

A 24 Volt DC power output is available to provide power to the sensors.
