What is the pressure gauges ? There are manyPressure gauges, for example ,according to Installation structure and mode , itcan be divided into two kinds, it is bottom connection and backconnection, if according to oil filledor not filled, it can be divided into two kinds. It is most basic! Next, I would like introduce two kinds ofpressure gauges, As follow:
Pressure gauges are instruments that measure the difference inpressure within a system and atmospheric pressure. They are used widely inindustrial processes to monitor the pressures of gases and liquids withincompressors, process lines, vacuum equipment and storage tanks. Domesticapplications include monitoring water pressure in mains supply, water tanks andswimming pool filters. Such domestic pressure gauges mostly use an analog andpointer display and can be easily rebuilt when damaged or rusty.
Follow the manufacturer’s instructions for the dead weightcalibrator to recalibrate the rebuilt pressure gauge. If this is impractical,enlist the help of a specialist or take the gauge to a garage or local hardwaresupplier for calibration.
Reconnect the gauge to the water system and use the wrench totighten the brass fitting at its base. Turn on the faucet to refill the watersystem. Turn on the power for the water pumping system to resume.
