U-tube manometer

U-tube manometer

[′yü ¦tüb mə′näm·əd·ər]
(engineering)
A manometer consisting of a U-shaped glass tube partly filled with a liquid of known specific gravity; when the legs of the manometer are connected to separate sources of pressure, the liquid rises in one leg and drops in the other; the difference between the levels is proportional to the difference in pressures and inversely proportional to the liquid's specific gravity. Also known as liquid-column gage.

The CVP values were measured using a U-tube manometer and were compared to the IVC diameters and collapsibility index, which were measured by bedside Ultrasound.
The CVP was measured using a U-tube manometer. The CVP results were recorded at the end of expiration in cmH2O.
In addition, when measuring CVP, we used a U-tube manometer instead of a piezoelectricity transducer.
The flow loop has a mercury U-tube manometer and a pressure transducer made from Rosemount Company to measure the pressure drop along the pipeline.
The flow patterns were observed and recorded using high speed video camera (hp CW450t) while the pressure drop was measured using pressure transducers and U-tube manometers. The effects of water cut, liquid velocity, and gas velocity on pressure drop and flow patterns have been studied systematically.
The hydrostatic pressure of a liquid is measured with a U-tube manometer. On the upper side of the cuboidal chamber, there is a membrane which is deformed more or less, depending on the pressure.
Experiments were carried out in a vertical tube of 0.019 m in diameter and 3 m length and the pressure gradients were measured by a U-tube manometer. It was found that in the annular flow regimes, pressure gradients increased with increasing Reynolds number.

The pressure drops across the test section are measured by using inclined U-tube manometers. The 15-liter tanks made of stainless steel are used for the storage of nanofluid and cold water.
In a similar R&D Magazine survey performed three years ago that focused on vacuum gauges, respondents used vacuum gauges that had a record for reliable operation, such as U-tube manometers and thermocouples, rather than new devices or ones that required maintenance.
