Single-point Settlement Meter
Kingmach Single-point Settlement Meter cover several ways to measure vertical deformation on civil and geotechnical projects. The category includes the JMDL-47XXAT smart single-point settlement gauge, JMDL-62XXADT inductive frequency-modulated hydrostatic level sensor, JMQJ-62XXADT micro range hydrostatic level sensor, JMYC-62XXAD wide-range differential pressure hydrostatic level sensor, and JMCJ-1003/1005 magnetic ring settlement water level gauge. Each product answers a different field question. A buried single-point gauge follows one embedded location in a roadbed, foundation, dyke, or tunnel invert. A hydrostatic network compares several elevations through connected liquid lines. A wide-range differential pressure system handles larger movement during reclamation or soft foundation treatment. A magnetic ring gauge separates layered underground compression from groundwater level change. Selection should begin with expected travel, required resolution, manual or automatic reading mode, access after burial, reference stability, and the structure being observed. This product group gives engineers a practical set of instruments for turning slow ground movement into named measuring points, dated baselines, and repeatable readings.
Application of Single-point Settlement Meter
In bridge deflection and pier foundation monitoring, Single-point Settlement Meter help engineers follow vertical behavior that may change with traffic, temperature, bearing response, scour, or foundation compression. Kingmach JMQJ-62XXADT micro range hydrostatic level sensors provide 50 mm and 100 mm ranges, 0.01 mm resolution, RS485 output, and IP68 protection for small movements near decks, piers, or abutments. JMDL-62XXADT hydrostatic sensors can connect several measuring points through tubes, allowing a bridge team to compare related locations against a common reference instead of reading each point alone. A practical layout may place sensors near pier caps, bearing seats, approach slabs, or foundation observation positions, depending on the risk being tracked. The daily review should not look at the settlement curve by itself. Traffic loading, temperature swing, inspection findings, bearing condition, river level, and nearby structural instruments give the curve meaning. If a pier point drifts while the deck and approach slab stay stable, the cause is different from a whole-span temperature response. Clear naming, stable reference control, and consistent reading intervals turn small vertical changes into usable maintenance evidence.
The future of Single-point Settlement Meter
The future of Single-point Settlement Meter will include cleaner digital handover records. Settlement monitoring often lasts longer than the construction team stays on site, so owners need more than a table of values. A useful handover file should include model, serial number, range, reference point, tube route, ring depth, baseline, installation photo, cable tag, borehole number, and first stable reading. Kingmach products such as JMDL-47XXAT and JMCJ-1003/1005 especially benefit from this because embedded rods, magnetic rings, anchors, and borehole readings may be hard to inspect later. When that information is stored with the curve, maintenance teams can understand why a point was installed and how its settlement should be interpreted years later. Future records should make the instrument history as visible as the measurement itself, so old readings can still be trusted after staff changes, repairs, and new construction stages.
Care & Maintenance of Single-point Settlement Meter
Hydrostatic Single-point Settlement Meter need regular checks of the liquid path. For systems using JMDL-62XXADT, JMQJ-62XXADT, or JMYC-62XXAD, inspect water pipes, connectors, sensor elevation, reference point, cabinet wiring, and tube protection. Kinks, leakage, air pockets, freezing risk, or construction damage can change the apparent settlement curve. Check whether readings change after pipe work, cabinet maintenance, or nearby excavation. For outdoor systems, protect tubes from vehicle traffic, sharp edges, workers, and animal damage. When a reading shifts suddenly, confirm the reference sensor and water path before treating the value as structural movement. Hydrostatic systems can be very useful, but they depend on a clean, continuous, well-documented connection between points. The record should include who inspected the point, what changed on site, and whether nearby instruments showed the same trend, so the maintenance team can separate sensor trouble from real settlement.

Kingmach Single-point Settlement Meter
Hydrostatic Single-point Settlement Meter are useful when several vertical movement points must be compared against a reference rather than read as isolated values. Kingmach JMDL-62XXADT and JMQJ-62XXADT use connected liquid paths and digital output to monitor vertical deformation in structures such as bridges, dams, tunnels, large buildings, and subgrades. The JMDL-62XXADT lists 50 mm, 100 mm, and 200 mm ranges with 0.01 mm resolution and RS485 output. The JMQJ-62XXADT micro range hydrostatic level sensor lists 50 mm and 100 mm ranges, 0.01 mm resolution, RS485 signal, and IP68 protection. These products are most useful when the tube route, reference point, cabinet, and baseline are documented clearly. If the reference is unstable, every curve downstream becomes harder to trust. A good point record also names the reference location, installation elevation, data channel, and maintenance access so later readings can be checked without guesswork.
