A wireless, passive embedded sensor was applied for real-time monitoring of water content in civil engineering materials such as sands, subgrade soils, and concrete materials. The sensor, which ...

Copper piping is used between inlet valve and 6” beyond outlet valve (shown in red). Meter setting space must be correct. For a 5/8” water meter (default size), it requires 292 – 305mm (11.5” – 12”).

This letter presents a CMOS compatible micro flow sensor (MFS) that operates in a thermal feedback (TF) mode. The proposed MFS contains four parallel polysilicon resistors on the micro bridges. The ...
