TR water meters have a structure that is designed for exterior environments and against though atmospheric conditions such as rain, humidity, dust etc. Having IP*8 impermeability class, TR water meters may work even under the water without affecting its performance. TR water meters show a superior metrologic performance through its mechanism manufactured with high technology and allow water consumption to be measured in the fairest way. Undesired particles in water such as sand, lime cannot affect mechanism group of TR water meters, thanks to its dry type design.TR water meters manufactured in compliance with regulation ***4/*2/EC show a superior performance against wear in high flow rates, much better than required criteria.Its interior non-return valve prevents inverse flow of water. 
ADVANTAGES 
Being a real dry type water meter, its prevents register group from being affected from negative factors of the network such as possible impurties. Performance of TR meters maintain the same performance even in case of rainfall, flood or any type of atmospheric conditions.T-pipe connections, bend pipes and similar installation applications do not affect the performance of the water meter.
