Bourdon manometers
Bourdon manometers correspond to the group of direct pressure displacement meters. It is a
reliable instrument. An outline of this type of manometers is presented in figure below
curved tube with smoothed traverse section will be deflected toward it was when it is
internally pressurized. A bond with an indicative needle can measure the deflection. With a
correct design we can get an extreme reliability, of the order of +0.1 % of the scale of
commercial instruments.
Pressure in a fluid
The force per unit of area is called pressure Pof the fluid
The unit of pressure according to the International system is the Pascal (Pa).
1 Pa = N/m?
1 bar = 10° N/m? = 10° kN/m = 10 Pa
1 kg/cm - 10 kg/m = 98070 Pa = 0.98 bar
Experimental procedure
1-Calibration of a Bourdon manometer
1. We should have a precision balance to determine the weight of the piston and masses
previously.
. Place the equipment on a flat and even surface and connect the supply tube that connects
the inferior area of the cylinder to the input of the manometer by means of a push-in fitting.
The output of this manometer should be prolonged, by means of a flexible tube, from the
drainage valve until its free end is settled inside an empty recipient to avoid splashes.
3. Disassemble the piston and determine accurately its weight.
4. Also determine the weight of the masses (if it has not been previously made).
5. Cover the piston with Vaseline for a best operation.
6. Fill the eylinder with water or oil.
7. Open the valve of the manometer.
8. When the air of the system has been eliminated, put the one way valve in the flexible tube
that comes from the upper part of the cylinder. Later on, close the output valve of the
manometer and, immediately later, stop introducing water in the equipment. We will have
the whole system full of water then.
9. Introduce the piston totally inside the cylinder.
10. Repeat these steps adding to the piston, in a staggered way, the different masses of the
given set of weights.
11. Once completed the test, remove the piston and dry it. Lastly, empty the cylinder.
12. Do not leave the piston inside the cylinder when it is not being used.
