Ultrasonic Level Indicator
Ultrasonic sensor melakukan transmit dan receive gelombang ultrasonic di bawah kendali microprocessor. Waktu transmisi ultrasonic (t) di udara digunakan untuk menghitung jarak (s) antara medium dan ultrasonic sensor. Karena speed (c) gelombang suara di udara memiliki nilai tertentu, maka berdasarkan persamaan: s = ct / 2, nilai s dapat dihitung. Karena jarak (H) dari ultrasonic sensor ke bagian bawah container adalah tetap, maka level medium yang akan diukur adalah H = H – s.
