settlement gauges

Magnetic gauges lower a probe into a borehole to find magnetic rings fixed along the casing, giving point measurements at set depths. Liquid-level systems use a pressure transmitter in a fluid-filled tube to detect changes in hydrostatic head, so they can monitor a continuous profile. Magnetic setups are simpler to install and cost less upfront, but liquid-level gauges lend themselves better to automated, long-term monitoring along a horizontal line.

Yes, most models output analog voltage or digital signals that fit standard geotechnical loggers. We supply wiring details and can recommend compatible logging equipment for remote or real-time data collection.

Consider the depth you need to monitor and how many points you want. For deep single-point monitoring, magnetic gauges with long cables work well. If you need a vertical profile with sensors every few meters, a multi-point vibrating wire system might be better. Our application engineers can review your borehole logs and suggest a configuration—including lengths, materials, and readout options.

Typical resolution falls within 1–2 mm for most models under field conditions. Magnetic gauges depend on the probe’s sensitivity and the operator’s technique; liquid-level systems can be more precise but are sensitive to temperature changes. We calibrate each gauge before shipping and include a calibration sheet so you know the baseline.

We provide written guides and can arrange on-site or remote training for your crew. Proper grouting and alignment are critical to avoid measurement drift, so we walk you through those steps and can review your installation plan beforehand.
