Harwil L-21N/L-21VCR Level Switch
Harwil® type L-21N & L-21VCR industrial level switches are low cost, high performance switches made from highly durable plastics. They feature a variable liquid differential and a single point pump up/pump down level control. Interchangeable differential band modules, for all non L-21+ versions, allow for 5 minute on-site switching of differentials from 1″ to 2″ to 3″ to 5″ in any sequence to satisfy variable operational requirements as they occur.
