The sewage treatment gate waterproof magnetostrictive level gauge provides continuous level measurement in harsh wastewater environments. Its sealed probe and IP68 housing resist moisture, sludge, and corrosive gases, making it suitable for gates, channels, sumps, and equalization tanks.

Key technical parameters include a measuring range from 300 mm to 6000 mm, with custom lengths available. Accuracy is +/-0.5 mm or +/-0.05% FS, and resolution is 0.1 mm. The instrument typically operates on 24 VDC (12-36 VDC), with output options of 4-20 mA, RS485/Modbus RTU, and HART. Process connection can be flange, thread, or bracket mounting. Wetted materials include 304/316L stainless steel, PTFE, or PVDF. Protection rating is IP68, and explosion-proof versions are optional. The medium temperature range is -20 C to +80 C, and ambient temperature is -20 C to +70 C. Pressure rating is up to 1.6 MPa, and probe diameter is usually 12-20 mm. Repeatability is 0.05% FS, and long-term stability is 0.1% FS/year.

The gauge uses non-contact magnetostrictive sensing for high stability, low maintenance, and strong anti-interference performance. A local LCD or remote controller can display level values. Optional local display and remote transmitter are available for flexible installation. For sewage gates, select a waterproof cable gland, surge protection, and an anti-corrosion probe. The probe should be grounded to reduce signal noise. Regular calibration and cleaning help maintain reliable level data.
