(2) Before mounting the sensor unit into the frame, sufficiently
apply silicone filler (or silicone-free grease
entire transmission surface of the sensor unit, taking care not
to introduce bubbles (Fig. 3-13).
Note) When using silicon-free grease, pay attention to the
fluid temperature range. The fluid temperature range
is shown below.
Silicon rubber: −20 to 100°C
Silicon-free grease: 0 to 60°C
When using silicon-free grease, reapply it on the

The range is set in the following procedure.
According to a selected range value, an analog output (4-20 mA DC) is delivered.
A pulse is outputted every time the integrated value attains a pulse value.
(Note: Must be carried out after setting the piping parameters in Section 3.4.)

4.5.6. Setting the total
4.5.6.1. Setting the total pulse (pulse value, pulse width)
Description
Set for total a process variable (flow rate) by total meter, etc. according to total pulse output.
z
Pulse value: Total amount (volume) per pulse.
z
A pulse is outputted when the total volume has attained an amount set by the pulse value, and adds to the total pulse
count (in case of total pulse indication).
Settable range: 0.000001 to 99999999.
* Set the total unit before setting the pulse value (see Section 4.6.3.).
Pulse width: Width of total pulse output.
z
Select a pulse width according to a corresponding total meter out of menus.
Settable range: 5 ms, 10 ms, 50 ms, 100 ms, 200 ms.
Note: If the output is through DO2 (relay contact), select 50 ms or longer (see Section 4.5.7.).
Restrictions in the setup
z
Output of total pulses involves the following restrictions depending on the DO output port (DO1, DO2).
DO output port
DO1: Transistor open collector
DO2: Relay contact 1 pulse per day to 1 pulse per second50ms, 100ms, 200ms
Furthermore, the maximum output frequency is restricted also by the setup of the pulse width.
Therefore, set the pulse width and pulse value so that both of condition 1 and condition 2 indicated below are
satisfied.
Correct motions may not occur, if any setup that does not satisfy both of condition 1 and condition 2 is made.
Condition 1:
1 FLOW SPAN-1
86400
[Hz]
PULSE VALUE [m
Condition 2:
FLOW SPAN-1
PULSE VALUE [m
Note 1) [m3

]
Note 1: The range of FLOW SPAN-1 or FLOW SPAN-2, whichever is larger, is the object in the case of 2-range setup.
Note 2: Restrictions in the maximum output frequency of each output port is also applied when the flow rate exceeds
the set range. Therefore, if such a setup that the maximum frequency occurs at the time of 100% flow rate of
the set range is made, there is a possibility where the total pulse output is incapable of following when the flow
rate exceeds 100% and accurate total value cannot be obtained if over-range continues for a long time. If
there are cases where the flow rate exceeds 100%, therefore, review the range and pulse value so that the
maximum frequency will not exceed the restricted level.

Noise level
Received waveform
Send interference wave
generated timed with trigger.
Pipe inside echoic wave (generated only in case
of V method mounting).
Generated partiqularly in metal pipe.
Not received waveform although sometimes
greater than received waveform.
Points
1. The received waveform must exist in LOW zone (window) at WID level of CH2 (WID). If off-positioned,
check the piping parameters.
2. The magnitude of received waveform must be about 1 Vpp.
(1) If lower than 1 Vpp: The reception sensitivity is too low. Take an action referring to the item of
"Measurement value does not change while flow rate does (LED lit red)" in "Section
5.6.3 If measurement value is abnormal".
(2) If higher than 1 Vpp: The flow transmitter may be faulty. Specify details of anomaly to us.
3. The overall noise level must be lower than 0.2 Vpp. Excessive noise may be caused by the following.
Cause Check
Special cable is faulty. Check the continuity, and measure the insulation resistance.
Polarity of connected terminals is inverted. Check the connection.
Detector is mounted erroneously
(S/N deteriorated).
Influence by external noise.
Take action referring to item "Measurement value does not
change while flow rate does (LED lit red)" in "Section 5.6.3
If measurement value is abnormal".
Detector bonding surface is peeling. Peel off the detector and recommence the mounting.
Wiring is poor. Whether special signal cable is passed through metal
conduit or wired together with power cable or heavy duty
line.
Poor contact.

Extension of time base
of received waveform
Time base variation
Points
1. Before reaching the maximum amplified signal wave, the number of waves must be 3 to 5. If the startup of
received waveform is not sharp enough, then the piping parameter input may be wrong or the detector mounting
may be not proper. Check the piping parameters, and how the detector is mounted referring to "Measurement
value does not change while flow rate does (LED lit red)" in "Section 5.6.3 If measurement value is abnormal".
2. Peak (amplitude) variations are not allowed. If peaks fluctuate up and down, bubbles are mixed. Take an
action referring to the item of "Ingress of bubbles" of "Measurement value does not change while flow rate does
(LED lit red)" in "Section 5.6.3 If measurement value is abnormal".
3. The time base must not fluctuate. If it does, there may be influence by turbulent flow or drift current. Take an
action referring to the item of "Measurement value fluctuates excessively while flow rate is constant." in
"Section 5.6.3 If measurement value is abnormal".
