Note: The process temperature must not exceed the operating temperature range of
the transducers.
Note: The ultrasonic transducers are not intended for use across boundary walls of different
hazardous area classifications. The transmitter electronics cannot be remote mounted
from a Division 1 classification to a Division 2 area to meet an area classification.
Communications specifications
Connectivity protocols One serial RS-232/RS-485 ports (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 BaseT
• Up to 10 Mbps
• Modbus TCP
Device compatibility FloBoss 103, FloBoss S600 flow computer, ROC 107,
Digital, analog, and frequency inputs
Digital Input(s)
(Selectable)
(1) Single polarity (for flow calibration gating - contact closure)
– Single input for starting and stopping
– 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 supply is available to provide power to the sensors.
