Multispan WLC-22 vs WLC-35 — Single-Tank vs Two-Tank Level Control
Both Multispan water-level controllers use conductive electrodes; the WLC-22 automates one tank while the WLC-35 coordinates two. Choose by the number of tanks.
Both the WLC-22 and WLC-35 are electronic water-level controllers using conductive electrodes. The WLC-22 automates a single tank — filling or draining with one pump. The WLC-35 coordinates two tanks, typically a source (underground sump) and a destination (overhead), controlling the transfer between them with dry-run protection. Choose by the number of tanks in your system.
Which to choose
Which should you choose?
Choose the WLC-22
For a single tank — an overhead tank that fills from the mains, or a sump that is pumped out — with one level-controlled pump.
Choose the WLC-35
For a two-tank system — a source (underground / sump) and a destination (overhead) — where the controller runs the transfer pump and protects against dry running.
