FIELD: measuring equipment.
SUBSTANCE: this group of inventions relates measurement of pressure in production processes. More precisely, it is related to pressure measurement by means of a filling pipe. The declared group of inventions includes a pressure sensor, and also a method for measurement of pressure in a production process. Thus the pressure sensor includes the sensor of pressure difference having the first port, the second port and an outlet related to pressure difference between first and second ports; the first filling pipe executed with possibility of connection of the first port with the first pressure of the process; the second filling pipe executed with possibility of connection of the second port with the second pressure of the process; and the sensor of physical properties of the first filling pipe connected to the pipeline of the process, configured for measurement of pressure of the filling fluid medium in the process pipeline as a function from change of physical properties of the first filling pipe. The method for measurement of pressure in the production process includes the following stages: they connect the first filling pipe to the process pipeline for measurement of the first pressure of the process; connect the second filling pipe to the process pipeline for measurement of the second pressure of the process; measure pressure difference with use of the sensor of the pressure difference connected to the first and second filling pipes; also measure pressure in the process pipeline on the basis of change of physical properties of the first filling pipe.
EFFECT: providing more exact measurements of a flow.
