Manometreja

Manometreja is the field and practice concerned with measuring pressure using manometers and related instruments. The term is used in some languages to refer to manometry or the instrumentation and methods for obtaining pressure readings in fluids or gases. It covers both the selection and use of devices as well as the procedures and standards involved in obtaining reliable pressure data.

Principles and devices commonly involved in manometreja include devices that translate pressure into a readable output. Classic devices are U-tube and inclined manometers that balance a fluid column against the system pressure. Other types rely on mechanical displacement from a Bourdon tube, a flexible diaphragm, or a bellows. Digital and electronic manometers convert the mechanical response into electrical signals for display and recording. Readings can be absolute, gauge (relative to atmospheric pressure), or differential (the difference between two pressures).

Measurement, calibration, and maintenance are central concerns in manometreja. Accurate readings require proper calibration against traceable standards, temperature compensation, and consideration of the fluid or gas properties. Installation practices matter to avoid hydrostatic or dynamic errors, leaks, and pulsations. Instruments must be chosen for the expected pressure range, chemical compatibility, and environmental conditions.

Applications of manometreja span industrial process control, HVAC, hydraulics and pneumatics, and clinical settings where pressure monitoring is essential. The discipline intersects with related concepts such as manometers, barometers, and general pressure measurement techniques, emphasizing accuracy, safety, and appropriate interpretation of readings in real-world systems.
