3.3. Flow transmitter wiring
3.3.1. Precautions in wiring
(1) Use a special coaxial cable (FLYA) as a signal cable between the detector (FSS) and flow transmitter
(FLR). Do not provide a junction of the signal cable midway.
(2) Be sure to pass the signal cables through a metal conduit between the detector and flow transmitter.
Upstream and downstream signal cables may be put in the same conduit but, to avoid an interference, do
not put the power cable together.
(3) For output signal, use a shield cable, where possible.
(4) To avoid ingress of noise, do not put the cables together with heavy duty line or the like into the same
duct.
(5) If a ground wire is included in the power cable, connect it to ground as it is.
(6) A power switch is not provided on the instrument and must be mounted separately.
(7) Hermetically cover unused wiring ports by furnished caps.
3.3.2. Applied wiring
Use the following cables.
Power cable : 3 or 2 core cabtyre cable. (Allowable temperature: 65°C or more)
Nominal cross-sectional area 0.75 mm2min.
Finish outer diameter 11 mm.
Output signal cable : 2 or, as required, multiple core cabtyre cable. (Allowable temperature: 65°C or more)
Finish outer diameter 11 mm.
Detector-flow transmitter cable : Signal cable by type designation (heat-resisting high-frequency coaxial cable having
50 of characteristics impedance. With one-side waterproof BNC connector).
Finish outer diameter 5 mm.
3.3.3. Treatment of wiring ports
The outer case of flow transmitter is waterproof (IP65). However, if installed in a humid place, the wiring ports must be
made airtight to avoid ingress of moisture, condensation, etc. Be sure to use the waterproof glands furnished with the
instrument in order to ensure the waterproof means. Hermetically seal unused glands by furnished caps.
Do not install the instrument where there is a risk of inundation.
