LF410/LF600 LF410/LF602 10 Wiring Precautions (1) Explosion proof type flowmeters are not provided cable glands. Refer to the part Cable connection port at detector and converter. (2) Connect the grounding wire (IV wire 5.5mm² or more) to a good earth ground (100 Ω or less ground resistance).
LF410/LF600 LF410/LF602 11 Piping Precautions (1) Design piping so that t he flowmeter detector pipe is always filled with the fluid being measured, whether the fluid is flowing or not. (2)The detector has no adjustable piping mechanism. Install an adjustable short pipe where needed.
LF410/LF600 LF410/LF602 12 Meter Size To select the meter size: See Figure 13 and find meter sizes within the velocity of 0.1 to 10m/s for a specified full-scale (measuring range high limit) flow. Select one that has its full-scale velocity between 1 and 3m/s.
LF410/LF600 LF410/LF602 13 About establishment environment Do not store or install the flowmeter in: • Places where there is direct sunlight. • Places where excessive vibration or mechanical shock occurs. • Places where high temperature or high humidity conditions obtain.
