1. OVERVIEW
This PUX2 is a portable type ultrasonic flowmeter that allows easy measurement of flow rates
in pipes by installing a set of sensors on the outside of the piping.
A combination of the latest electronics and digital signal processing technologies enables the instrument
to provide a compact and convenient solution to accurately measure system flow rates without breaking or
opening the serial transmission and removable memory card functionality allows easy dataacquisition and
analysis.

4. NAME AND EXPLANATION OF EACH PART
•Keyboard : Used for turning on/off power supply of the main unit, controlling the
printer, inputting fluid specifications and setting the transmitter functions.
•Display window : Displays measured value. Also used for display during programming and
data input.
Because this is a large-size graphic LCD, indications are easy to read.
Even at a dark place, indications can be read by using the backlight.
•Printer (option) : Capable of printing all information of the transmitter including print of
display screen capture and printout of measured value.
*Transmitter includes a logger function (for storing measured values in
memory). After storing a few day's data in memory by the logger function,
it may be printed.
Note) Chinese language selection will print Japanese.
•Detector : Attached to a pipe and receives/transmits ultrasonic waves.
•Cable for exclusive use:
Used for transmitting and receiving signals between transmitter and detec-
tors for flow measurement.
• Rubber : Protects the main unit from drop impact etc.

4.3 Handling of SD memory card
Use an SD memory card for recording measured data, flow velocity profile data and screen data.
The equipment is capable of accommodating an SD memory card of capacity up to 8GB. An
SD memory card of capacity 256MB is provided as an option.
Compatible media
• SD memory card
Speed class: Class2, 4, 6
• SDHC memory card
Speed class: Class4, 6
4.3.1 Precautions for handling of SD memory card
(1) Use an SD memory card or SDHC memory card that has been formatted based on a standard.
(2) Make sure to format the SD memory card or SDHC memory card based on its standard.
(3) Firmly insert the SD memory card (or SDHC memory card; hereinafter the same) in the appro-
priate direction, and assure that it has been properly mounted.
(4) Do not remove the card during data read/write operation. Data may be broken or erased.
It is recommended that data stored on the card is periodically backed up.
Important data is lost if the SD memory card is broken. Make sure to back up the data on the
SD memory card.
4.3.2 Formatting forms
For formatting an SD memory card, use dedicated formatting software the memory card manu-
facturer provides. Data read/write is not permitted if the card is not property formatted.
Formatting forms
• FAT12: 64MB
• FAT16: 128MB, 256MB, 512MB, 1GB, 2GB
• FAT32: 4GB, 8GB
