Pressure gauges are commonly used to monitor the flow rate of water in a system. This helps ensure that the water supply meets the needs of the people who use it.
There are two main types of pressure gauges – absolute and differential. Absolute gauges measure the total pressure in a pipe or vessel. Differential gauges measure the difference between the pressures at different points along a pipe or vessel.
If you need to read a pressure gauge, first make sure that the gauge has been calibrated correctly. Calibration refers to the process of adjusting the reading so that it matches what the actual pressure is. This ensures that the gauge is accurate.
Once you have determined that the gauge is properly calibrated, you will need to install it into the system. You should do this before turning on any faucets.
If you are unsure how to test the accuracy of a pressure gauge, then you should follow these steps. First, turn off the main valve at the source of the water supply. Next, open the shutoff valves on each fixture downstream until the flow stops. Then, check the pressure gauge. If the reading is correct, close the shutoff valves and turn on the main valve. Repeat the process with the other fixtures.
