Pressure sensor for monitoring of distribution points of district utilities for heat and water

Improving the economy of the district heat operation requires a detailed analysis of the entire value chain starting at the heat generation plant, following the distribution network and ending with demand side. Extra efficiency can be achieved by replacing human work with remote monitoring via Internet or GSM communications and using networks of wireless sensors for collecting data. This procedure is called remote readout or automated meter reading (AMR). Different sensors are deployed for measuring parameters (liquid flow, pressure and temperature) required by water and heat distribution. These sensors communicate each other with using IEEE 802.15.4 standard radio protocol forming together a wireless network. Presented paper focuses on design, implementation and testing of a system-on-chip based pressure sensor for monitoring of water quality in distribution points of district utilities.
