4.9.1. Setting of flow rate range
4.9.1.1. Setting of flow rate range (single range)
Description
The range (full scale) of flow rate to be measured is set.
* The analog output (4-20mA) corresponds to the range setting.
Settable range: 0.3 to 10 [m/s] in terms of flow velocity in piping
* The piping parameters and FLOW UNIT must be set beforehand.
* If a value beyond the settable range is inputted, "INPUT ERROR" appears and then last
setting is resumed.
* If "piping parameters" or "FLOW UNIT" has been changed after setting the range,
recommence the range setting.
<Note> The flow rate unit is as selected by "FLOW UNIT" in the "MEASURE SETUP" mode.
(Refer to Section 4.8.2.)
・
Setting range of the full scale frow rate
<Note> Converted flow rate in the Table 1 is the calculation results obtained
by using the internal diameters of pipes in the left columns.
Perform calculation using the actual internal diameters for accuracy.
Simple formula for calculation of flow verocity
For actual keying, refer to the typical operation indicated below. Set the protection to OFF beforehand. (See Section 4.4.1.)
Operation
Set the range type to single range and "FULL SCALE1" to flow rate 60m3/h.
(example)
* Set the piping parameters and "FLOW UNIT" beforehand.
