Submersible Level Transmitters

Submersible level sensors take constant level readings by measuring the hydrostatic pressure emitted by a liquid in a tank. Hydrostatic pressure measures the density of the fluid and the height of the fluid. Assuming the density of the fluid is constant, the change in hydrostatic pressure is due to the height of the liquid in the tank. The atmospheric pressure above the liquid line affects the hydrostatic pressure at the bottom of the tank as well as the level of the liquid in the tank. Tanks that are vented or not pressurized do not have a constant atmospheric pressure. In these situations, the submersible level sensors have their own venting to make up the difference, allowing the device to keep its readings reliable.

TEK-TROL Tek-Sub 4800A PTFE Submersible Level Transmitters are designed for continuous submersion in aggressive fluids and provides excellent corrosion resistance in most liquids. Tek-Sub 4800B Submersible Level Transmitters provide reliable level measurement in a wide variety of applications are are equipped with a ventilation tube that automatically compensates for changes in atmospheric pressure above the tank. 

Tek-Sub 4800C Borehole Submersible Level Transmitters and Dwyer Mercoid MBLT Miniature Submersible Level Transmitters are narrow in diameter and are ideal for conduit installations such as boreholes, wells and slender pipes. 

Tek-Sub 4800D Wastewater Submersible Level Transmitters and Dwyer Mercoid PBLT2 and PBLTX Submersible Level Transmitters are designed specifically for slurry and wastewater applications. The clog-free silicon piezoresistive sensor determines liquid level without being affected by debris. The instantaneous level output is used for pump control to maintain the level or to report the real-time level status.
