Critical Technical Advantages
-
Compact Borehole Compatibility: The ultra-slim design (22mm diameter) allows the sensor to be deployed in confined spaces where standard sensors cannot fit. This is particularly advantageous for groundwater monitoring in small observation wells.
-
Certified for Drinking Water: The FMX11 holds multiple prestigious approvals, including NSF61, ACS, KTW, and DVGW. This guarantees that the materials in contact with the media will not contaminate the drinking water supply.
-
Robust and Durable Construction: Built for long-term submersion, the sensor features a robust design that withstands the environmental stressors found in rivers, lakes, and dams.
-
Tailored for Your Application: The device can be ordered with specific cable lengths (ranging from 6m to 30m) and measuring ranges up to 2 bar, allowing for a “plug-and-play” experience without the need for extensive field calibration.
-
Simplified Installation: As a straightforward hydrostatic sensor, commissioning is intuitive. By measuring the weight of the water column above it, the FMX11 provides a linear signal proportional to the level, unaffected by surface conditions.
