Abstract
The present disclosure relates to a method and an apparatus for measuring a flow rate through a vessel, such as a conduit or pipeline. The method comprises providing a reference parameter, measuring a first parameter at a first position at the vessel and determining a difference between the first parameter and the reference parameter. The flow rate through the vessel is determined based on the difference between the first parameter and the reference parameter.
Claims10
A method for measuring a storage volume in a storage tank, the method comprising:
- providing a surrounding environment reference temperature;
- measuring a first temperature using an infrared radiation sensor at a position at the storage tank;
- determining a difference between the first temperature and the reference temperature;
- and
- determining the storage volume in the storage tank based on the determined temperature difference,
- wherein the measuring of the first temperature is at a distance from the storage tank to the position at the storage tank;
- and
- wherein the measuring the surrounding environment reference temperature comprises measuring a ground temperature as the surrounding environment reference temperature.
An apparatus for measuring a storage volume in a storage tank, the apparatus comprising:
- a first sensor for measuring a first temperature at a first position of the storage tank;
- a second sensor for measuring a surrounding environment reference temperature, wherein the second sensor is positioned to measure a ground temperature outside the storage tank as the surrounding environment reference temperature;
- and
- a calculation unit for determining a difference between the first temperature and the surrounding environment reference temperature and for determining the storage volume in the storage tank based on the determined temperature difference;
- wherein the first sensor is an infrared radiation sensor.
A method for measuring a storage volume in a storage tank, the method comprising:
- providing a reference temperature of an environment outside the storage tank, wherein the reference temperature comprises a ground temperature outside the storage tank;
- measuring a first temperature at a first position at the storage tank;
- determining a difference between the first temperature and the reference temperature;
- and
- determining the storage volume in the storage tank based on the determined temperature difference;
- wherein the measuring of the first temperature is at a distance from the storage tank to the first position by means of an infrared radiation sensor.
