What Is a Water Pressure Gauge?
A water pressure gauge is a device designed to measure the pressure of fluids, such as water, flowing inside a water pipe. It is typically connected to a branch of a water pipe, allowing the measurement of the fluid’s pressure within the pipe. Water pressure gauges find applications in various scenarios, including civil engineering works, the installation of toilets, and water pipe systems. There are both mechanical and electronic water pressure gauges available, with some capable of storing measurement data for several hours.
Uses of Water Pressure Gauges
Water pressure gauges are employed in the construction of houses and factories that utilize fluids. They serve a variety of specific purposes, including the inspection of pipes in toilets, water supply systems, and drainage systems in civil engineering projects. Water pressure gauges are also crucial for inspecting water supply facilities during factory startups and managing the water pressure of chemical solutions in industrial settings. When selecting a water pressure gauge, factors to consider include its pressure measurement range, compatibility with the type of fluid it will handle, characteristics such as pH tolerance, ease of maintenance, and connectivity with other equipment.
Principle of Water Pressure Gauges
The operation principle of water pressure gauges involves the use of a pressure sensor, a pipe joint for connection to a water pipe, and a display. The joint is typically designed as a screw, allowing it to be attached to a branch of a water pipe for pressure measurement. Digital water pressure gauges may store data collected from the sensor in memory or transmit it to other devices, often serving as switches for other equipment.
During operation, the water pressure is measured using a pressure sensor. The specific type of pressure being measured is static pressure, which can be obtained by installing the measuring section perpendicular to the direction of water flow within the pipe. The pressure sensor itself comprises a piezoelectric element that deforms in response to pressure changes, generating an electrical signal that represents the pressure measurement. When measuring water pressure in a water pipe, it’s important to perform the measurement while water is flowing, as the specified water pressure must be maintained during water drainage. In such cases, the water pressure may be lower compared to when water is not draining, so attention to detail is necessary.
