A measurement device for measurement of liquid contained in a tank, particularly a fuel tank on an aircraft or boat. The device has a first pressure sensor for mounting outside the tank, on a liquid outlet pipe connected to the tank to measure the pressure of liquid in the outlet pipe. A second pressure sensor measures the pressure in the ullage space above liquid in the tank. A venturi flow meter mounted in the outlet pipe measures liquid flow through the outlet pipe. The device also includes an accelerometer. The quantity of liquid in the tank can be calculated in response to measured values received from the pressure sensors, the accelerometer and the venturi.
