The LMK 351 screw-in level transmitter is designed for measuring the level of Hypochlorous acid, which is formed when chlorine dissolves in water.
To ensure compatibility with the media, the LMK 351 can be manufactured with specific materials. These include a housing made of PVDF (Polyvinylidene fluoride), a speciality thermoplastic, an FFKM O ring seal, and a PTFE foil that is processed over the ceramic capacitive pressure sensors.
