Flow Meter
Alat yang digunakan untuk mengukur besarnya aliran bahan bakar dalam pipa adalah flow meter, yang terdiri dari dua unit, yaitu flow meter untuk aliran yang menuju ke mesin diesel dan flow meter untuk aliran yang kembali ke tangki. Kedua flow meter ini memberikan sinyal atau data ke flow consumption indicator. Jenis flow meter yang digunakan untuk bahan bakar ini dirancang khusus untuk mengukur aliran dengan akurasi tinggi.
Flowmeter yang digunakan untuk Fuel Consumption yaitu :
