Exploring Pressure Sensors in Water Distribution Networks for Combatting Water Loss

Water utilities and distribution networks encounter a significant obstacle known as "non-revenue water", which refers to the water loss that occurs throughout their networks that does not generate any revenue.

This loss can be attributed to two primary sources: actual losses that result from leaks in pipes, joints, and fittings, as well as apparent losses caused by inaccuracies in metering and unauthorized consumption. Such losses can account for 30-50% of the water input into the distribution networks.

Water utilities are seeking creative solutions to this challenge to minimize non-revenue water, particularly as the world becomes more intelligent and interconnected.

Solution

Implementing pressure sensors at various points in the water distribution network is an efficient and economical method of mapping the water network of a given area. This mapping enables utilities to identify and target locations of unexpected water loss.

Typical nodes, such as hydrants and commercial and residential water meters, are suitable for integrating pressure sensors.

Sensata Technologies, a renowned leader in pressure sensors, has designed the PTE7300. This product has low-power digital I2 C electrical output and is available in a module or fully hermetic package.

The module is a cost-effective solution, providing customers with greater design flexibility. The fully hermetic sensor is rated to IP69K ingress protection and includes a 5-pin M12 connector with gold pins and a glass-to-metal hermetic seal within the connector. Both package options are compatible with drinking water.
