hydrostatic level sensor

Kingmach Measurement & Monitoring Technology Co., Ltd. produces hydrostatic level sensors as part of its geotechnical instrument line. The working principle is straightforward: a pressure-sensitive diaphragm at the probe tip measures the weight of the liquid column above it, then converts that into an output signal proportional to the level. Most of our sensors use either a ceramic or a diffusion silicon sensing element, housed in 316L stainless steel for corrosion resistance. Temperature compensation is built into the electronics to keep the readings stable across seasonal shifts. We don’t publish a single spec sheet because every project has its own demands—some need a 4-20 mA output for a legacy SCADA system, others want RS485 with Modbus protocol. Our standard cable lengths go from 10 meters up to 200 meters, but we’ve shipped custom lengths beyond that for deep groundwater applications. The accuracy typically sits around 0.25% or 0.5% of full scale, though we can tune that if the application requires tighter control. Beyond the hardware, our global distribution network means we can deliver to site quickly, and our technical support team can guide you through the installation and calibration. Whether it’s a dam monitoring project, a wastewater treatment plant, or a river gauging station, we treat each order as a custom solution rather than an off-the-shelf sale.
