Sight glass. Water gauge on a steam locomotive. Here the water is at the "top nut", the maximum working level. Note the patterned backplate to help reading and toughened glass shroud. A sight glass or water gauge is a type of level sensor, a transparent tube through which the operator of a tank or boiler can observe the level of liquid

A valve is required to open at 500 psig inservice where the service temperature is 400° F, and back pressure = 25 psig. Differential set pressure = 500 psig – 25 psig = 475 psig. Temperature multiplier: 1.013. Cold differential test pressure = 475 psig x 1.013 = 481 psig. This valve would have a stamped set pressure of 500 psig and a CDTP of

The sensor senses the temperature. Based on the aquastat setting, this will limit the high temperature in the boiler to prevent overheating. The cutoff temperature for most hot water boilers is 180° F. There is a differential setting to make sure the boiler does not short cycle or run unnecessarily. Low Limit - The low limit has two purposes.
