Seiring dengan perubahan ketinggian air, tekanan air diukur menggunakan osilator kuarsa, yang menghitung ketinggian air dari frekuensi osilasi. Pengukuran dengan akurasi tinggi, tanpa kesalahan konversi yang disebabkan oleh perubahan sekuler yang biasa terlihat pada diafragma. Memiliki rentang pengukuran yang luas, dari 10 meter hingga 70 meter, sangat cocok untuk pemantauan ketinggian air pada sungai dan bendungan.
■ Pengukuran akurasi tinggi dengan osilator kuarsa
■ Pemasangan yang mudah pada revetment dan struktur
■ Perawatan dan pengelolaan yang sederhana dan mudah
■ Rentang pengukuran yang lebih luas
