EDS6-123I FUJI [Fuji Electric], EDS6-123I Datasheet - Page 5

• Manufacturer Part Number: EDS6-123I
• Description: ULTRASONIC FLOWMETER < M-Flow PW>
• Manufacturer: FUJI [Fuji Electric]

MEASURING PRINCIPLE
The transit-time technique uses a pair of sensors with each
sensor sending and receiving ultrasonic signals obliquely
through the fluid.
CONFIGURATION
(1) Single-path system (V method)
(2) Single-path system (Z method)
(3) When using synchronization

tic coupler in ordinary cases. Silicon rubber is sup-
plied in a tube (100g). If one or more detectors are
ordered, silicon rubber may be selected once every
5 orders or so.
Select silicon-free grease (B) for the use in an envi-
ronment where generation of silicon is not desirable
such as semiconductor manufacturing facilities. The
silicon-free grease is soluble in water. Therefore,
do not use it in an environment subject to splash of
water or where condensation tends to occur on the
surface of the piping. The grease, which does not
become hardened, requires periodic maintenance
(cleaning and refilling of about once in 6 months at
room temperature).
