SML-S324 series are submersible hydrostatic level transmitters specially designed for sewage, sediment and silt‑laden media. Based on ceramic piezoresistive principle, they convert hydrostatic pressure into standard analog and digital signals. Equipped with IEC61000‑4‑5 Level‑4 lightning‑proof and surge‑protection circuits, the transmitters deliver strong anti‑interference performance. Multiple outputs, material options and wide measuring ranges are available for water plant, sewage treatment, deep well, dam and flood‑control level measurement.

SML-D322 split submersible level transmitter uses diffused silicon piezoresistive sensing principle to convert liquid hydrostatic pressure into standard analog or digital signals. It supports multiple customizable outputs, IP68 submersible probe, optional anti-corrosion wetted parts and cables, suitable for water supply, sewage, hydropower, chemical and marine liquid level monitoring.

This SML-HP323 corrosion‑resistant submersible hydrostatic level transmitter adopts robust **ceramic measuring cell** as sensing element, equipped with PTFE anti‑acid‑alkali cable and optional anti‑corrosion wetted‑parts materials. It supports standard 4‑20 mA as well as various analog & digital signals for liquid‑level detection. Built‑in lightning and surge protection ensures stable performance under harsh working conditions including corrosive chemical liquid and sewage. Measuring range covers 0‑1 ~ 300 mH₂O, widely applied for chemical plants, sewage treatment and storage tank level monitoring.

SML-322 series submersible level sensor uses diffused‑silicon piezoresistive technology to measure hydrostatic liquid level from 0‑1 mH₂O to 300 mH₂O. Multiple analog & digital outputs, lightning/surge protection and wetted‑part material selections suit water, sewage, dam and irrigation projects. Various accuracy and temperature grades are configurable per order.
