The Series FBLT Submersible Level Transmitter is designed with a flush diaphragm to prevent clogging in harsh applications such as sewage lift stations. Its narrow body design fits easily into stilling wells and narrow installations. The robust diaphragm is constructed with a PTFE-coated FKM fluoroelastomer that is stick resistant and resilient in aggressive fluids. The diaphragm cavity is filled with a gel that will not leak when compared to competitor units that use oil or grease. The body of the FBLT is constructed of 316 SS with a cable of either polyurethane or ETFE for added corrosive resistance.
