Input
Measured variable Direct measured variables
• Volume flow
• Flow velocity
• Sound velocity
Calculated measured variables
Mass flow
Measuring range
v = 0 to 15 m/s (0 to 50 ft/s)
Measuring range depending on the sensor version.
To calculate the measuring range, use the Applicator sizing tool →  75
Operable flow range Over 150 : 1
Input signal Output and input variants
→  16
External measured values
The measuring device provides optional interfaces that enable the transmission of externally
measured variables (temperature, density) to the measuring device:
• Analog inputs 4-20 mA
• Digital inputs (via HART input or Modbus)
Various temperature measuring devices can be ordered from Hauser: see "Accessories"
section →  76
HART protocol
The measured values are written from the automation system to the measuring device via the HART
protocol. The pressure transmitter must support the following protocol-specific functions:
• HART protocol
• Burst mode
Current input
The measured values are written from the automation system to the measuring device via the
current input →  14.
Digital communication
The measured values can be written from the automation system to the measuring via:
Modbus RS485
Current input 0/4 to 20 mA
Current input 0/4 to 20 mA (active/passive)
Current span • 4 to 20 mA (active)
• 0/4 to 20 mA (passive)
Resolution 1 µA
Voltage drop Typically: 0.6 to 2 V for 3.6 to 22 mA (passive)
Maximum input voltage ≤ 30 V (passive)
Open-circuit voltage ≤ 28.8 V (active)
Possible input variables • Temperature
• Density
