Standard Specifications 

IM 01G05B03-01E 1st Edition 

Fluid Temperature Range: 

General temperature type: 

–30 to +130°C (–22 to +266°F) 

High temperature type: 

–30 to +200°C (–22 to +392°F) 

Note:  Pay attention also to temperature specification of the 

couplant you choose. 

 

Connection Cable 

Connection cable is always necessary to connect the 
transducers (junction box) and the US300FM main unit. 
The length is specifiable from 1 m (3 ft) to 300 m (984 ft) 
by the meter. 

 

Accessories 

Fixing Hardware, Couplant, etc: 

Specified in the suffix code of US300FM/US300FT. 
Model codes as accessories also available for 
separate/additional orders (listed later). 

 

Data Transfer Software 

General: 

The software installed on a personal computer receives 
one or more records of logging data and parameter sets 
stored in US300FM main unit via RS232 
communication port. 
Data can be viewed or graphed on a PC monitor, or 
exported as a text file. 
This software works while US300FM is off-line (not 
measuring flow) where current output goes down to 
zero. 

Function: 

Displaying Parameter Record: 

Display parameter record of selected measuring data 
set. 

Displaying Measured Data in Table: 

Display measured data of selected measuring data 
set in table format. 

Displaying Data in Graph: 

Display measured data of selected measuring data 
set in graphic format. Marker type and color for each 
line of values selectable. Scales for time-axis and 
value-axis can be changed from default condition of 
automatic scaling. Graph printing function embedded. 

Displaying Statistical Data: 

Display statistical data of the measurement. Total 
data points, minimum, maximum, average and 
standard deviation of the measured data can be 
shown. Data range for statistical processing can be 
designated if necessary. 

Exporting Text File: 

Parameter record and measured data can be 
exported to a text file. Options for exporting items or 
their formats are available. 

Entering Remarks: 

User’s remarks for each measured data can be 
entered and edited in the transferred data file on a 
personal computer. Remarks can be displayed in the 
main window of the software. 

Display Language: 

English, German
