(L)
Transmitting
surface
Element holder

Loosen the lock nut and slide the sensor so as to
meet the specified mounting dimension (by
rounding off the displayed mounting dimension
value of the converter below the decimal point),
and then tighten the nut.
(4)
(1)
Apply the attached silicone grease to the
transmitting surface of the sensor. Spread the
compound over the entire area.
Keep the sensor retracted by turning the element
holder counterclockwise.
After cleaning the surface of the pipe, the sensor
should be mounted.
(2)
Fix both ends (saddles) of the sensor to the pipe
by the attached cloth belts. Mounting will be
facilitated by winding the cloth belts on the pipe in
advance.
Cloth belts are usable at 80°C or lower.
If above 80°C, stainless steel belts should be
used.
(3)
Make sure the sensor is mounted in parallel with
the pipe axis and the mounting dimension is
correct. Then, turn the element holder clockwise
until the sensor comes in close contact with
the pipe.
Stop turning the element holder when it tightens
as the transmitting surface comes in contact with
the pipe surface. Be careful not to tighten the
holder excessively.

6. OPERATION
(1) Make sure that the inside diameter of the piping being measured comforms to the
sensor type.
Be sure to read the following items and record (check) the next page before
using the flowmeter. Read these data together with the instruction manual.

(2) Check the lengths of the straight pipe upstream and downstream of the sensor mount-
ing position.
•Straight piping greater than 10D must exist on the upstream side and greater than 5D on the
downstream side.
•Elements (pump, valve, etc) on the upstream side must be greater than 30D away to prevent
disturbances.
(3) Check if the piping setting (outside diameter, material, thickness, etc.) is correct.
•If the sensor mounting size is not calculated correctly, errors will occur such as window scan
(reception range-over) or no received signal.
(4) Check if the sensor is mounted correctly.
•If the transmission side of the sensor is not coated sufficiently with silicone grease, receiving
signals will become unstable or errors will occur such as window scans (receiving range-over),
no received signals, etc.
•If the upstream and downstream side connectors are reversed, a negative flow rate will be
indicated.
(5) Make sure that the zero point adjustment is completed.
•Fill the piping with measuring fluid, then stop the flow of the fluid to perform a manual zero
adjustment.
(6) Check to see if more than 2 indicators on the upper right of the measurement screen
are working to indicate wave reception.
•If no indicator is displayed, or if only one is displayed, increase the level of the transmission
voltage.
(7) Check if the analog output range is set correctly.
•Even when the analog output is not used, an error of analog scale-over will occur unless the
analog output range has been set properly.
* Preparations for measurement have been completed.
Set the integrator, logger, printer, etc., as necessary. Check whether the flow rate is indicated
correctly. If an error message is indicated, display the system check screen and press the
ENT key while setting the cursor on the error checker.
At this time, the error data, the cause of the error and procedures to correct the error are
indicated. Operate the flowmeter according to the instructions.

(1) Check the inside diameter of the piping to insure it conforms to the sensor type.
(2) Check for sufficient lengths of straight pipe upstream and downstream of the sensor
mounting position.
(3) Check for correct piping settings (outer diameter size, material, thickness, etc.).
(4) Check for correct sensor mounting.
(5) Check the zero point adjustment.
Zero point adjustment method: Manual zero clear (stop the flow of fluid for manual zero opera-
tion.)

Treatment of detector mounting side
•Using thinner and sand-paper, remove the
pitches, rust and uneven surface of the detector
mounting piping over the entire mounting area
of (L) + 200mm wide.
•When the piping exterior is wrapped with jute,
remove the jute and then perform the above
treatment.
•Horizontal piping should be mounted within
±45°from the horizon.
•Vertical piping can be mounted at any external
position.
•Insufficient mounting space (about 1/2 of the size of
the V method)
Small diameter sensor and small type (standard)
sensor should be mounted by the V method.
In the following cases, the Z method should be
used for mounting.
•Piping with mortar lining
•Piping is old and presumed to have a deposit of a thick
layer of scales inside the piping. 1)Loosen the lock nut. After setting to the
mounting position, tighten the lock nut.
2)Coat the sensor transmission side with a
sufficient amount of silicone grease.
3)Attach both ends (saddle) to the piping
using a cloth belt.
4)Make sure that the sensor is mounted in
parallel with the piping and that the
mounting position is correct. Then, turn the
element holder clockwise until the sensor is
firmly fitted to the piping (clockwise;
element moves down, anti-clockwise;
element moves up).

Important !
Insufficient coating of grease on the sensor
Air stays in the piping.
When the inside of the piping is rusted or the lining material is
peeled off, the number of indicators will not increase even if the
transmission voltage is raised.
When transmission voltage is raised unnecessarily, the battery
power will be consumed quickly during battery drive
(no problems with measurement ).
Important !
This is the result of automatic calculation.
It can be changed by piping specification input.

Module-to-module communication failure (major fault)
Internal data communication is abnormal.
•Reset the power source. (SW ON - OFF)
•If the instrument does not recover, it is an indication of malfunction. Contact your
dealer for repair.
Measurement module failure
Measurement module is abnormal and cannot be used for measurement.
•Reset the power source. (SW ON - OFF)
•If the instrument does not recover, it is an indication of malfunction. Contact your
dealer for repair.
Calculation failure
Measurement calculation is abnormal.
•Confirm the set data.
•Reset the power source. (SW ON - OFF)
•If the instrument does not recover, it is an indication of malfunction. Contact your
dealer for repair.
Printer failure
The printer has a problem and cannot be used for printing.
•Is the printer power turned on?
•Check to see if paper is jammed. Also, make sure that the printer is connected
correctly to the main unit.
•Reset the power source for the main unit and printer.
Receiving signal fluctuation
Measurement is impossible due to fluctuation of received ultrasonic waveform.
•Check to see if a large quantity of air bubbles or foreign objects have entered
the piping.
•Change the sensor mounting position.
•Remove the cause of air bubbles or foreign objects.
•Check if the dedicated cable is improperly plugged in or disconnected.

Window scan
Received signal is lost in the measurement window. It is being searched.
•Check the setting of piping data.
•Open the PIPE PARAMETER screen. Measurement operation is reset
and window scanning will start (It is not an error).
No received signal
Ultrasonic waveform is lost.
•Check the setting of piping data.
•Check the sensor mounting size.
•Check the connection of the cable.
•Raise the transmission voltage.
Receiving signal overflow
Overflow of the strength of ultrasonic received signal

Temporarily set the sonic speed and the coefficient of kinematic viscosity of an approximate fluid
(water soluble fluid is regarded as water), and obtain a measured value of sonic speed.
If the sonic speed is not known at all, temporarily set the sonic speed by the following steps within
the range 500 to 2500m/s.

Item (8) .
2) Coefficient of kinematic viscosity:
Referring to Table 1 “Coefficient of
kinematic viscosity”, set the coefficient of
kinematic viscosity of an unknown fluid
approximate to the fluid name (kind of fluid).
(Note that this is not the coefficient of
kinematic viscosity of fluid approximate
to the sonic speed of the measured fluid.)
Important !
Setting of "Sonic speed"
and "Coefficient of
kinematic viscosity" of
unknown fluid
•Open "SITE SETUP" page.
•Change the setting from
