Abstract
Günlük yaşamda farklı alanlarda durağan veya hareketli durumlarda sıvı seviyesinin ölçümünün doğru bir şekilde gerçekleştirilmesi gerekmektedir. Sıvının türüne, hassasiyete ve maliyete göre temaslı/temassız sensörler kullanılabilir. Bu çalışmada sıvı seviye ölçümünde kullanılan ultrasonik sensör, kapasitif sensör, diferansiyel basınç transdüseri, kızılötesi sensör ve dikey hareketli şamandıranın çalışma prensipleri incelenmiştir. Örnek bir uygulama olarak silindire yakın bir şekle sahip bir kaptaki su seviyesinin ölçüm işlemi sensörler ile gerçekleştirilmiştir. Kaptaki farklı seviyelerde gerçekleştirilen ölçümlerde gerçek su seviyesine yakın değerler sensörlerden okunmuştur. Sensör seçiminde temaslı /temassız, sürekli/ayrık zamanlı veri alma gibi durumlar göz önünde bulundurulur. Sensörün çalıştığı ortamın sıcaklığı gibi parametrelerin göz ardı edilmesi ölçüm hatasının artmasına neden olmaktadır. Sensörlerin kalibrasyonunun doğru yapılması ölçme hatalarının azalmasını sağlayacaktır.
