In many regions of the world, water is very scarce. The wasting of water through undiscovered leaks in water pipes can therefore cause great damage. The very sensitive Diehl ultrasonic water meters can be used to detect leaks in pipes. They are at the same time especially robust, durable and can also be used in difficult climate zones. In contrast to mechanical meters, ultrasonic technology is insensitive to air bubbles or suspended particles in the water.
