DEVICE FOR WEIGHING LIQUEFIED NATURAL GAS Russian patent published in 2018 - IPC G01G17/04 

FIELD: measuring equipment.

SUBSTANCE: invention relates to the field of weighing technique and can be used for weighing liquefied natural gas. Device for weighing liquefied natural gas consists of a load receptor, a container, at least one load cell containing strain gauges, an analog-digital converter. In order to improve the accuracy of measurements, simplify the calibration and calibration procedures, it introduces the interface connector, computer and display. Load receptor is a cryogenic tank that allows receiving both liquid and vapor phases and is equipped with at least two pipelines for receiving and delivering the liquefied natural gas weighed and its vapor. Supply pipelines are equipped with bellows expansion joints to reduce the influence of external factors on the weighing results up to permissible values. For the replacement of strain gauges, the design of the device provides for the presence of plates in the bases of the insertion points, each of which contains a deadbolt that allows the sensors to be retrieved in verification.

EFFECT: ensuring the possibility of weighing natural gas in liquid and gaseous aggregate states, as well as metrological verification taking into account the requirements of explosion safety.
