gauge water level

For deep or hard-to-access boreholes, a submersible pressure transducer with a cable strong enough for its own weight is often the most practical. Vented types automatically compensate for barometric pressure, but non-vented works with a separate barometric sensor at the surface. The choice comes down to whether the extra cost and smaller cable diameter of a vented gauge are justified by the required accuracy.

You can, but the material matters a lot. Standard stainless steel sensors corrode quickly in saltwater or brackish environments. Kingmach can supply gauges with Hastelloy or ceramic-body sensors that hold up longer. It’s always worth mentioning the water chemistry when you specify, because even “clean” groundwater can become aggressive when it mixes with drilling fluids or leachate.

Most industrial loggers accept a 4-20 mA analog loop or a digital RS-485 (Modbus) signal. Before ordering, check your logger’s input configuration and available power—some transducers need a regulated 10–30 V DC supply. Kingmach ships instruments with the output you request, and the wiring schematics are included. If you’re unsure, the support team can review your logger model and suggest the right signal option.

Accuracy depends on the technology. A simple dipmeter might get you within 1 centimeter, which is fine for many groundwater monitoring wells. Pressure transducers are typically specified at 0.1% to 0.25% full scale, but remember that the effective accuracy at the water surface also depends on barometric compensation and temperature drift. For critical applications, calibrating the gauge in the actual installation borehole improves confidence more than relying on factory specs alone.

Yes. For construction dewatering or short-term pumping tests, portable dipmeters or reusable pressure transducers are commonly used. They can be rented or purchased, and the team can recommend a rugged cable design that copes with frequent handling. After the project, the instruments are often recalibrated and redeployed on the next site, which keeps costs down for contractors.
