Standard Specifications 

IM 01G05B03-01E 1st Edition 

Arithmetic Operation on Optional Dual-Channel / 
Dual-Path Inputs: 

Arithmetic operations get the outcomes for calculation 
channel Y and Z by taking sum, average, or difference 
of two flow values from input channel A and B. Taking 
absolute values of each input independently in the 
calculation is also possible. 

Note:  Two sets of transducers are necessary. 

Pulse Output (optional): 

Available via optional binary outputs. 

 Pulse value: 0.01 to 1000 of totalization unit 

 Pulse width: 100 to 1000 ms (±20%) 

 Maximum output rate: 2pps (pulse/second) ±20% 

Alarm Output (optional): 

Available via optional binary outputs where each alarm 
item is assigned one-to-one. Alarm properties are also 
selectable for each alarm one-by-one. 

 Alarm items: High limit, Low limit, Flow direction 

change, Quantity limit (for batch operation), and Error 
(measurement impossible) 

 Alarm properties: Normal open / Normal close, Non-

hold / Hold (at the alarm detection) 

Output Signal Configuration: 

Freely configurable including independent dual flow 
value outputs. 

  Current / frequency outputs: Flow velocity, Volume 

flow, Mass flow, Sound velocity, or Signal amplitude 

  Binary outputs: Pulse or Alarm 

Data Logging Function: 

Data storage capacity of 27,000 values. 
Storage rate is selectable from 1 s, 10 s, 1 min, 10 min, 
30 min, 1h, or any other rate between 1 s to 43200 s 
(12 h) by the second. For each period of measurement, 
stored values are grouped by a user-defined measuring 
point name. 
Stored values can be transferred to a personal 
computer via RS232 serial communication port. 

(Note)  As the RS232 port is on the front panel inside 

housing, use this function only for test / service / 
maintenance purposes. 

Communication Function: 

Transfers the measured values to a personal computer 
or a serial printer. Both on-line/off-line transfer 
during/after the measurement available. 

  Output item: Flow value (flow velocity, volume flow, 

or mass flow), Totalization (forward, reverse), Sound 
velocity, Signal amplitude 

  Output format setting: Spacing (for printer), Decimal 

point character, Data delimiter 

 Communication interface: RS232 

  Communication port: D-sub 9-pin, male 

(Note) As the RS232 port is on the front panel inside housing, 

use this function only for test / service / maintenance 
purposes. 

Time-Programmable Measurement Function: 

Automatic start / stop of the measurement without 
human operation using internal clock for specific 
systems. Can be used with current output, binary output, 
data logging function, and/or communication function 
for recording the measurement. 

Site Parameters Storage Function: 

Eliminates the necessity of re-entering parameters for 
additional measurement on a site. 
Totally 80 sets of site parameters for pipe/fluid settings 
are available with user-defined site names. 

Material / Fluid List Customization Function: 

The lists of material / fluid in the parameter menu are 
editable. Unnecessary items can be cut off from the 
menu for user’s convenience. Registration of new 
material / fluid data is also possible totally up to 13 
items with user-defined names. 

Power Supply: 

Power supply voltage: 

100 to 230 VAC ±10% (50/60 Hz ±5% ) or 
24 VDC ±10% 

Power consumption: Less than 15 W 

Safety and EMC Standard: 

General safety: EN61010-1:2010 
              EN61010-2-030:2010 

 Altitude at installation site: 

Max. 2000 m above sea level 

 Overvoltage category: 

Overvoltage category II 

 Pollution degree: 

Pollution degree 2 

EMC regulation: EN61326-1:2006 

Operating Conditions: 

Ambient temperature: –10 to +60°C (14 to 140°F) 
Ambient humidity:  0 to 95% RH or less (Non-condensation) 

Note:  Lengthy operation at 80% or more is not 

recommended. 

 

Transducers 

Basic Construction: 

A set of transducers are composed of a pair of sensor 
elements (often called just as “transducers”), and 
transducer cables with a junction box at one end, which 
is to be connected to US300FM main unit by dedicated 
connection cable US300FC. 
The transducer cables are armed with stainless steel 
flexible tube. 

(Note)  Fixing hardware (fixing strap, clips, etc.) and acoustic 

couplant are usually included in a set of transduces, 
specified in its model code by their kinds or 
with/without. 

Material: 

Case of sensor elements: 

Stainless steel EN/DIN 1.4571 (JIS SUS 
316Ti, AISI 316Ti SS equivalent) 

Sensing surface of sensor elements: 

General temperature type: PEEK (Poly 
Ether Ether Keton) 
High temperature type: Polyimid 

Degrees of Protection: 

General type: IP65 (EN60529) 
Immersible type: IP67 (EN60529) 

Applicable Pipe Sizes (inner diameter): 

Medium type: 25 to 400 mm (1 to 16 inches) 
Lager type: 100 to 2,500 mm (4 to 98 inches) 
Very large type: 2,000 to 6,500 mm (78 to 255 inches) 

(Note)  Only “6,500 mm” above is the size for outer diameter.
