Water Level Data Loggers for Field & Remote Monitoring
water level data loggers
A monitoring network is only as good as its weakest link — and often that link is the data logger’s ability to talk to field sensors. Kingmach water level data loggers are designed to remove that headache. They accept the common industry protocols like 4-20mA analog inputs and digital Modbus RTU, so you can pair them with most pressure transducers, ultrasonic sensors, or radar gauges already installed in groundwater wells, streams, or reservoirs. The internal memory holds months of time-stamped records, and data retrieval can be done locally via USB or remotely through an optional cellular module. Whether you are running a single-point spot check or a 20-node network across a catchment area, the logging interval and alarm thresholds can be configured on site. Kingmach is not a general-purpose electronics brand; we are geotechnical instrument manufacturers. That means our support engineers understand what happens when a borehole floods or a logger gets buried in silt after a storm — and they will help you design the monitoring setup that survives it.
Technical Detail
Configured around process stability, mold life, and long-term uptime.
Kingmach water level data loggers are built for the realities of environmental and geotechnical monitoring. The input stage handles both voltage and current loop sensors, so you are not locked into one sensor brand. Most loggers in this product line offer two or four independent channels, each with its own excitation supply and programmable engineering unit conversion. This is practical when you need to track water level alongside temperature or a secondary depth sensor for barometric compensation. Data files are stored in non-volatile flash memory and carry a timestamp with resolution down to one second. Users typically configure the device through a simple Windows application; no proprietary programming language is required. For sites with cell coverage, the logger can be ordered with a built-in 4G/LTE modem. It then pushes data to a cloud server on a customizable schedule, or sends alarm SMS messages when a level threshold is crossed. The housing is cast aluminum with a sealed connector that stands up to high humidity and occasional submersion. At larger installations, a single Modbus master can poll multiple loggers daisy-chained on RS-485, reducing cabling. Kingmach stocks a wide range of compatible sensors, cables, and mounting brackets, so most projects can be fulfilled from a single purchase order. Custom firmware tweaks — such as a special averaging algorithm or a non-standard baud rate — are often feasible for OEM or large-scale deployments. Because the engineering team sits next to the production line, turnaround on technical questions is typically same-day.

Common technical questions
What types of water level sensors can I connect to the logger?
The logger accepts 4-20mA current loop sensors (common on submersible pressure transmitters) and 0-5V / 0-10V voltage output devices. It also supports Modbus RTU over RS-485, which covers many ultrasonic and radar sensors. Basically, if the sensor has a standard industrial interface, you can use it.
How do I get the recorded data out of the logger?
Locally, you can connect a laptop via USB and download the CSV files using the free configuration tool. If you add the internal 4G modem, the logger uploads data to a cloud platform automatically, and you can view the readings in a web browser. Some users pull the data into SCADA through Modbus TCP, using an optional Ethernet module.
Can one logger monitor multiple wells?
It depends on the model. Single-channel loggers handle one sensor. If you have two or three nearby wells, a multi-channel version can wire each sensor back to one logger, which saves cost and simplifies data collection. We also offer RS-485 nodes that let one master unit poll many single-channel loggers spread over a large site.
What kind of maintenance do these loggers need in the field?
Very little. The enclosure is IP65, so it resists rain and dust. The field connector has a gasket that stays tight if you close it correctly. The main weak point is the onboard battery if you use one; rechargeable packs last about two years in moderate temperatures with a daily data push. We advise swapping the battery pack every 18 months as a precaution, or using a solar panel kit for truly remote sites.
We have an existing SCADA system. Will your logger integrate with it?
Yes, the logger can act as a Modbus slave device on RS-485 or TCP/IP. Your SCADA software just needs to poll the relevant registers. We can provide a register map and a sample configuration for popular SCADA platforms. If you need a different protocol, talk to us; firmware customization is one of our strong points.
