Wastewater Submersible Level Transmitter


The Tek-Sub 4800D Wastewater Submersible Level Transmitter is exclusively designed for slurry and wastewater applications. Manufactured for precise level measurement, its clog-free silicon piezoresistive sensor determines liquid level without being affected by debris. Packaged in a stainless steel housing, the waterproof cable makes it ideal for long-term trouble-free service.The Tek-Sub 4800D is capable of real-time level measurement with several standard output signal options. The instantaneous level output is used for pump control to maintain the level or to report the real-time level status.
This high-performance level measurement device is available with several level ranges, custom cable lengths and materials, ensuring an ideal match for the application requirement.
