Technical Characteristics and Reliable Design
-
Compact Borehole Compatibility: The ultra-slim 22mm probe diameter allows for easy insertion into narrow gauge pipes and boreholes where traditional sensors cannot fit. This makes it a preferred choice for groundwater monitoring and resource management.
-
Drinking Water Certified: The FMX11 is constructed with materials that comply with global drinking water standards (ACS, KTW, NSF61, DVGW). It is engineered to monitor water production and storage without risking contamination.
-
Simple Installation and Operation: Designed for “plug-and-play” utility, the transmitter features a fixed measuring range and cable length tailored to the user’s specific order. This simplifies commissioning as the device arrives ready for immediate deployment.
-
Robust Construction: Despite its small size, the probe is built for long-term durability in surface water and groundwater. It provides stable measurements in environments ranging from calm lakes and storage tanks to moving rivers and dams.
-
Integrated Overvoltage Protection: To ensure continuous operation in outdoor gauging stations, the electronics are designed to be robust against environmental electrical surges.
