Light-Shielding Film for Digital Water Meters

Water meters protect our planet’s most valuable resource by helping ensure that its consumption is charged fairly. They serve as the interface between public utility networks and private-sector residential buildings and business facilities. Lorenz GmbH & Co. KG uses light-shielding films from Schreiner ProTech for reliable reading of digital water meters.  

Water meters indicate the volume of water that has passed through them. That is why they have to be calibrated. Digital water meters using wireless technology for data transmission are particularly accurate. A light barrier installed in the sensor ensures the accuracy of the information transmitted. Ambient light must be prevented from penetrating the housing. Otherwise, the light barrier would not operate properly and incorrect data might be forwarded.

A precision light-shielding film that Schreiner ProTech has developed for Lorenz prevents this. It is applied inside the housing precisely around the water meter and prevents the penetration of external light rays. The light-shielding film ensures that all readings are obtained reliably and correctly.

Efficient data acquisition and transmission combined with systematic data analysis provide major opportunities for enhancing the quality of water supply systems. Significant savings can be achieved by detecting waste, localizing leakage, and reducing the need for related service travel. The metering technology employed is decisive for capturing and transmitting the data required by water utilities quickly and reliably.
