•The piping must be filled with fluid which is free from air bubbles and foreign objects.
•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.

(2) Detector mounting considerations
1) For horizontal piping, the detector should be mounted within ±45°from the water level.
For vertical piping, the detector can be mounted in any external position.

Enter the piping specifications in the parameter of the converter to determine the sensor mounting
dimension and then mount the sensor on the piping.

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.
