Abstract
Bu çalışmada PVC su borularındaki su seviyesini tespit edebilecek bir RF güç iletim düzeneği oluşturulmuştur. Tasarlanan iki mikro şerit dipol anten, bir RF güç alıcı – vericisi olarak kullanılmıştır. Antenler f_0=2,45 GHz ISM bandında çalışmak üzere tasarlanmıştır. PVC su borularının içerisindeki suyun seviyesini, su ile görsel bir temas olmadan ve boruya fiziksel bir müdahalede bulunmadan tespit etmenin çok az yolu vardır. Bu çalışmada saf suyun elektrik geçirgenliğinin, havanınkinden yaklaşık 80 kat daha fazla olmasından yararlanarak boru içindeki suyun doluluk oranına göre iletim katsayısı belirlenmiştir. Boru içerisindeki su miktarı arttığında iletim katsayısı değişimi tespit edilmiştir. Benzetim programından ve ölçümden elde edilen iletim katsayısı değerlerine göre, boru kesitindeki suyun miktarı belirlenmiştir. PVC Boru içerisindeki su miktarının %0, %20, %50, %80 ve %100 değerleri için iletim katsayısının yaklaşık -20 dB ile -60 dB arasında değiştiği gözlemlenmiştir. Tasarlanan düzenek, boru içindeki su miktarının doğrusal karakteristikte tespit edilebilmesine olanak sağlamaktadır.

Abstract
In this study, a power transmission setup was created to detect the water level in PVC water pipes. The two identical micro-strip dipole antennas designed were used as an RF transceiver system. The antennas were designed for the f_0=2.45 GHz ISM band. In this study, the transmission coefficients were determined according to the filling ratios of the water in the pipe by making use of the fact that the permittivity of distilled water is approximately 80 times higher than that of air. When the amount of water in the pipe increases, the changes of the transmission coefficient were determined. Thus, the water level in the pipe section can be determined according to the transmission coefficient values obtained from the simulation and measurement. It was observed that the transmission coefficient varies between -20 dB and -60 dB for 0%, 20%, 50%, 80% and 100% of the water in the PVC Pipe. The designed setup allows the water level in the pipe to be determined in a linear characteristic.
