Original LEFOO LFT3020 manufacturer model and specification source
LFT3020 — interchangeable anti-clogging filter
LFT3020 is a submersible pressure-derived level transmitter with a removable/filter-selectable anti-clogging head, separate from LFT3010’s named sediment-ring arrangement. The maker gives distinct accuracy categories at the 0.5–1 mH₂O low span and higher 1–200 mH₂O spans. Choose the correct sensing tip for the liquid and suspended solids while leaving a cleaning/retrieval procedure. Match A4 current, V05 ratiometric or RS485 output to its required supply and host scaling; do not assume each interface has the same power connection.
