3.3. Flow transmitter wiring

3.3.1. Precautions in wiring

CAUTION

(1) Use a special coaxial cable (FLY3) as a signal cable between the detector (FLS) 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.

Nominal cross-sectional area 0.75 mm Finish outer diameter ∅11 mm.

Output signal cable : 2 or, as required, multiple core cabtyre cable.

Finish outer diameter ∅11 mm.

Detector-flow transmitter cable : Special signal cable by type designation (heat-resisting high-frequency coaxial cable

having 50 Ω of characteristics impedance, provided on a side with waterproof BNC connector). Finish outer diameter ∅5 mm.

min.

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.

CAUTION

Do not install the instrument where there is a risk of inundation.

(2) Before mounting the sensor unit into the frame, sufficiently

apply silicone filler (or silicone-free grease entire transmission surface of the sensor unit, taking care not to introduce bubbles (Fig. 3-13).

Note) When using silicon-free grease, pay attention to the

fluid temperature range. The fluid temperature range is shown below. Silicon rubber: −20 to 100°C Silicon-free grease: 0 to 60°C When using silicon-free grease, reapply it on the transmission surface of the sensor unit approximately once every 6 months. (Silicon rubber need not be reapplied.)

(3) Then insert the sensor unit into the frame, align the slit

provided on the pressing fixture of the sensor unit with graduations located on the frame top surface (see Fig. 3-14), and press the sensor unit until the fixture claws are engaged with the frame side square holes. Mount both sensor units so as to be roughly symmetrical with respect to the frame (see Fig. 3-15).
