[Setting of fault tolerance]
Setting selection can be made to enable continuance of measurement (‘ON’) or discontinuance of
measurement (‘OFF’) as long as measurement is enabled even if equipment malfunctions occur
or when there is no received signal. Measurement is possible under the following conditions.
• In case of totalizer memory failure
• During multi-path measurement, in case one measurement path remains in
operation when a malfunction or no received signal condition occurs with respect to other
measurement paths.
Note1: See Fig. 4-4: Measurement Aberration Transition Diagram under Chapter II-2-7, ‘Output
Operating During Aberrations in Measurement'.
Note2: Although measurement accuracy is not affected by the tolerance function during memory
failure, totalized values will be inconsistent.
Note3: When tolerance operation is activated during multi-path measurement, measurement
accuracy will deteriorate.
Note4: Measurement will automatically recommence when a received signal is obtained even
during no received signal processing.
[Digital output (RS232C output)]
Measurement values of flow, etc., and status can be output via RS232C.
CH1 of the digital output (RS232C output) is a dedicated output port. The data output cycle can
be changed. Fixed unit is sec., and the setting range is 0 to 3600 seconds.
CH2 of the digital output (RS232C output) is a bi-directional port. Connected to a PC, this port
enables flowmeter setting by the PC and monitoring of measurement values, etc.
Baud rates for each channel can be selected from the following.
4800BPS, 9600BPS, 19200BPS
Note: Commissioning software is necessary for flowmeter setting with PC.
[Flowmeter, flow velocity measurement mode]
By changing the measurement mode, the unit can be used as a flow velocity meter. Flow velocity
values in the flow velocity meter mode are displayed as linear flow velocity values.
