cabling type for pulse transmitter/counter and water meter
Posted: Sun Jan 24, 2016 11:36 am
I understand that a 18-20 gauge Cat5 UTP cable, for a distance of up to 200ft between my flow meter and my pulse counting device, will be adequate to avoid signal loss or attenuation.
I only need 18-2 (18 gauge, 2 conductor) wire for this, and I want to use direct burial from flow meter to side of building. At which point I will run the cable from outside and into building and then wire up my pulse counting device. Commercial systems when I've worked before typically use "icky-pick" direct burial Cat5 cable to connect flow meter to pulse transmitter, but it is generally restricted to outdoors only, due to fire hazard of gel-filling in cable sheathing.
Question: Which direct burial 18-2 cables would be good for a max. 200ft. from flow sensor/flow meter to pulse transmitter, if part that cable run would be going inside a building?
18/2 Plenum Communication Cable
2 Conductor 18 AWG Unshielded Fire Alarm Cable FPLP
2C/18 AWG BC STRANDED SHIELDED DIRECT BURIAl
PLENUM Rated 18/2 Security Cable Stranded CMP Fire Alarm/Control Wire
Do I have to make sure I am using twisted pair in any case to avoid signal loss?
