Gauges and meters

Instruments that show what is happening in the system: pressure in the booster set and boiler, heating water temperature and water consumption.

• Pressure gauges — for setting a pressure switch or reducing valve and checking the air charge in a pressure tank.
• Thermometers and combined gauges — for the boiler room, water heater and mixing units.
• Water meters — for metering and an easy way to find a hidden leak.

How to set a pressure switch using a gauge is explained in “Adjusting a pressure switch”.
