Flowline
Level transmitters, switches, and flow switches — plus a 285-chemical materials compatibility reference identifying where 316 stainless steel corrodes.
What LibertyCES specifies from Flowline
LD33 is explicitly named for corrosive chemical service with PTFE/FEP wetted material; LD32 for wastewater lift stations.
LU10 is the only intrinsically safe switch in the line and named for chemical/solvent/light oil service; LZ12 is named specifically for wastewater.
316 stainless steel — often assumed the "safe" default — rates Corroded against 29 common chemicals in this reference table.
Frequently Asked Questions
Is 316 stainless steel always safe for chemical service?
No — Flowline's own 285-chemical materials compatibility table rates 316SS as Corroded for 29 common chemicals, including sodium hydroxide, sulfuric acid, hydrofluoric acid, hydrogen peroxide, and hypochlorous acid. In nearly every one of those rows, PVDF or PTFE rates Excellent or Good instead.
Which Flowline sensor is rated for corrosive chemical service?
The LD33 pressure/submersible transmitter, with PTFE/FEP wetted material, is explicitly named for corrosive chemical service. The LU10 ultrasonic switch is the only intrinsically safe switch and is named for chemical, solvent, and light oil service.
What is the range of the Flowline LR85 radar level transmitter?
Up to 196.8 ft on solids or 393.7 ft on liquid, with a PFA-wetted antenna suited to low-dielectric-constant media — the longest range in the Flowline level transmitter line.
