Integrated Wide-Range Differential Pressure Water Level Meter
The Kingmach integrated wide-range differential pressure water level meter tackles a common field headache: fluctuating water levels that drift beyond typical sensor limits. Instead of swapping instruments mid-project, this unit handles both shallow and deep measurements in one go. It uses differential pressure sensing with built-in temperature compensation, so you get stable readings even when surface conditions change fast. The integrated design means fewer cables and connections to worry about during installation. For groundwater monitoring, open channel flow, or reservoir level tracking, it keeps data consistent across seasons and weather swings. Kingmach ships these meters with user-adjustable output ranges and optional SDI-12 or RS-485 interfaces, matching most data loggers without extra converters.
Technical Detail
At Kingmach, we build the wide-range differential pressure water level meter around a practical need: reducing the number of sensors on a monitoring network. The meter measures water pressure against atmospheric reference through a vented cable, calculating level with an onboard microcontroller. Its range spans from submeter accuracy in shallow wells to tens of meters in deep boreholes—one device covers what often takes two or three fixed-range probes. The housing is 316L stainless steel with a ceramic sensing element that resists corrosion from brackish or contaminated water. Cable lengths are customizable up to 300 meters, and the connector has an IP68 rating for permanent submersion. We calibrate each unit in a temperature-controlled bath before shipment, and provide a calibration certificate with every order. Common uses include dam seepage monitoring, tidal study, and dewatering projects where level changes are extreme and unpredictable. The meter runs on low power, typically 5–12 V DC, and outputs either 4–20 mA or digital signal. Our support team can pre-configure the output scaling to match your specific water column.

A differential pressure meter compensates for atmospheric pressure changes in real time by using a vented cable. A basic submersible pressure transmitter measures absolute pressure and requires separate barometric correction. The differential approach eliminates that extra step and often yields better accuracy for long-term level monitoring.
It means the device maintains accuracy across a broad span—for instance, accurately reading 0.5-meter levels and 50-meter levels without needing to swap sensors or change calibration settings. This is useful in applications like reservoir drawdown or tidal zones where the water column can vary drastically.
Yes. The output options (4–20 mA, SDI-12, RS-485) connect directly to most data loggers and RTUs. Kingmach can preset the signal range to match your system’s input requirements before shipping.
Minimal maintenance. The ceramic element and vented cable should be checked annually for blockage or damage. The vent tube uses a desiccant cartridge to prevent moisture ingress; replacing the desiccant once a year is recommended. No recalibration is typically needed unless the sensor has been physically damaged.
Yes, the 316L stainless steel body and ceramic diaphragm handle most aggressive environments. For highly acidic or chemical-laden water, we offer optional Hastelloy housings. It is always best to share water quality details with our team so they can recommend the right materials.
