The Flowline LD35 DeltaSpan Pressure Level Transmitter is a general purpose small-bore wastewater pressure level transmitter that provides continuous level measurement up to 30' (9.1m) of water column with a 4-20 mA signal output. Select the LD35 liquid level sensor for dirty, foaming or slurry type liquids. Application examples include sewage lift stations, industrial slurries, industrial sumps, landfill leachate, reservoirs, sludge pits, and oil tanks.

Additional features of the Flowline LD35 DeltaSpan Pressure Level Transmitter include:

  • Corrosion resistant 316 SS transducer with polyurethane or ETFE cable
  • Strong cable design with maintenance free breather tube and vent filter
  • Incorporates lighting and surge protection
  • Robust PTFE coated FKM fluroelastomer diaphragm provides a non-stick surface for aggressive fluids
  • Clog-free diaphragm for use in harsh applications
  • Connects directly to PLC/SCADA or display
  • Narrow body design perfect for stilling wells and other narrow installations
  • Maintenance-free vent filter prevents water droplets and other particulates from fouling transmitter
