Water pressure test gauges

The manometer is useful for real-time monitoring of the pressure of a fluid in either liquid or gas state within a well-defined circuit. Calibrated in bar, PSI, or Pascal, it can be analog or digital.

There are a few details to know about the manometer used to control water pressure in a household's supply circuit:

- it allows for the control of water pressure at the meter's outlet, which should be at 3 bars;

- if a booster pump is used, it is installed after this device;

- its installation can be carried out by tapping into a pipe;

- it is possible to install it directly on a pressure regulator or a pressure reducer.

This device can be coupled with others to control water pressure in a dwelling:

- a booster pump if the water pressure is insufficient;

- a reducer if the pressure is too high;

- an adjustable pressure reducing valve also allows for the reduction of pressure in the piping;

- a pressure switch to divert the excess pressure to a third circuit.

Other manometers are available for various uses:

- the guns for controlling tire pressure;

- the devices for controlling pressure in a fuel oil tank;

- the devices for measuring pressure in an acetylene cylinder;

- the models dedicated to measuring pressure and vacuum in air conditioning systems are specially calibrated in Pascal (Pa);

- the devices specially designed for measuring pressure in an oxygen cylinder.

Thus, the choice of a manometer depends primarily on its use. In any case, its use satisfies a need for precise information about the water, air, or gas pressure in a circuit.
