Water Pressure Gauge
A water pressure gauge determines and monitors the pressure of any system that is water-based. Water pressure gauges are commonly attached to boilers and tanks that require monitoring of the liquid within.
At sea level, the atmosphere exerts an average pressure of 14.7 psi, commonly referenced as one atmosphere of pressure. Water pressure gauges use this number to calculate the pressure level in water. Water pressure gauges measure pressure above normal atmospheric levels. When a pressure change occurs, a metal tube within the gauge flexes, inciting a change in reading.
Monitoring of water pressure is important in devices and apparatuses that rely on hydraulics. For example, control valves that measure pressure, along with temperature and flow, control the fluid in hydraulic machinery. Hydraulic power is used in automotive, construction, military, and manufacturing industries, so water pressure gauges are highly utilized.
