Large oil-filled pressure gauge for home water purifier devices

Introduction

Usually, in most home water purifiers, there is a pressure gauge in the form of a needle gauge.

Of course, in some water purifiers, this gauge may not be present, which is not considered a defect and is not one of the main components of the device.

This gauge shows the water pressure output from the pump towards the membrane filter (stage 4 filter).

This gauge shows the fluid pressure so that the consumer or repairman is aware of the water pressure and can detect some defects in the device.

Gauges are of 2 types:

Oil gauges
Dry or air gauges.

There is a special oil (glycerin) inside the oil gauges, whose function is to neutralize excessive vibrations of the needle, and oil gauges also have a longer lifespan and higher performance.
