Basch later substituted a spring manometer for the mercury column.
A number of attempts have been made to measure the venous pressure by compressing the arm veins and noting on a manometer the force necessary to obliterate the vein.
This pressure is transmitted directly to themanometer =G=, and may be read off in centimeters of water on the accompanying scale.
Precautions When Estimating Blood Pressure= There are certain precautions which must be strictly observed when deductions are drawn from the manometer readings.
The vessel, b, was also connected with a mercury manometer and air pump by means of a T tube, p, v, one arm of which passed through the third hole in the lid of the apparatus.
The pressure should be raised by squeezing the syringe until the manometer registers one inch.
This result will be obtained, under good conditions, before the manometer indicates a pressure of five inches.

We were submerging, and the manometer showed seventeen meters.
The higher we came--one can read on the manometer how we are ascending meter by meter--the greater became the excitement and tension.
We, of course, had no fear, but I knocked impatiently on the manometer to see if the register would not at last begin to move.
Soon the Nautilus returned to her native element, and the manometer showed that she was about thirty feet deep.
The log indicated moderate speed, the manometer a depth of about sixty feet.
The pumps began to drive the water from the tanks; the needle of the manometer marked by a different pressure the ascent of the Nautilus, then it stopped.
Its level (the manometer showed) could only be the same as the outside level, for there must necessarily be a communication between the lake and the sea.
I then descended as deeply in the water as I could, the manometer showing thirty metres.
I then discovered that the manometer continued to register the same depth, and was also out of order.
This is done by closing the valve connecting the tension-equalizer with the system and admitting oxygen to the tension-equalizer until the petroleum manometer shows a definite tension.
The upper part of the cross is connected to a small rubber tubing and to the mercury manometer D, which also serves as a valve for passing a given amount of air through a series of U-tubes for analysis of the air from time to time.
A small air-pressure is applied and the variations in height of a delicate manometer noted.
The connected series of three U-tubes on the rack on the table is joined on one end by well-fitting rubber connections to the tube leading from the mercurial manometer and on the other end to the rubber tube A leading to the gas-meter.

All parts of the apparatus are open to the air, and the mercury in the manometer is adjusted so as to come to a fixed mark a.
By turning or withdrawing the support the substance enters the bulb; and during its vaporization the free limb of the manometer is raised so as to maintain the mercury at a.
Ewald formerly tested the strength of their bottles with a manometer before using them, but for some time past they have given up the practice, feeling convinced that it was productive of more harm than good.
If on being tested with a manometer the wine should indicate too high a pressure, it is at once removed to a cool cellar, consequently the average total breakage rarely exceeds 2¼ per cent.
A manometer worked by compressed air, an instrument used to ascertain the upper atmospheric pressure on the level of the ocean.
The manometer was wanting, and no summary estimation could take the place of it.
With his eyes fixed upon the dials of the manometer he gauged the earthward flight.
I called down to the central and got back the comforting answer that the large manometer was also indicating a depth of over forty meters!
A second glass tube provided with a stop-cock may be passed through the india-rubber cork and connected with a manometer to measure the progressive action of the pump (Figure 15).
Extinguish the gas and allow the manometer index to fall to zero.
Wait until the index of the manometer records a temperature of 120° C.
A mixture of nitrogen and hydrogen may be enclosed in a palladium vessel connected with a manometer (see Fig.
When the resulting pressure produces a condition of equilibrium, it is measured[9] by a manometer connected with the solution, much as a gas pressure may be measured (Fig.
The above list will hopefully give you a few useful examples demonstrating the appropriate usage of "manometer" in a variety of sentences. We hope that you will now be able to make sentences using this word.
