3. Other specifications

• Conductivity:

5μS/cm or more
(If detector is partially filled pipes type, conductivity is 100μS/cm or more)

• Power supply:

100 to 240VAC (allowable voltage range: 80 to 264VAC, 50/60Hz)

24VDC (allowable voltage range: 21 to 27VDC)

• Power consumption: 17W (27VA ) or less (when 7th digit of specification code is “A”)

35W (60VA ) or less (when 7th digit of specification code is “B”)
30W (50VA ) or less (when 7th digit of specification code is “F”)

When the 7th digit of specification code is “B” and “F”, power supply is 100 to 120VAC

(allowable voltage range is 80 to 132VAC, 50/60Hz)

When the 7th digit of specification code is “B” and “F”, 24VDC cannot be selected.

• For partially filled pipes detectors:

Fluid water level range:

Meter size 6”-12” (150-300mm) : Water level 1 1/4(30mm) to state to be filled with water

Meter size 14”-24” (350-600mm) : 10% of meter size to state to be filled with water

Note) State to be filled with water is water level 100%

Necessary straight pipe length:

Upstream side : 10D or more

Downstream side: 5D or more

Note) D is meter size.
