Sep 30, 2016 · Water level gauge glass tube cleaning The glass is full of rusty water and would like to know whether opening the valve on the bottom of the glass will be the right way to clean it. I started refilling the boiler but it doesn't clear it.
Gauge glass is a type of level sensor, a transparent tube through which the operator of a tank or boiler can observe the level of liquid contained within.
Water gauge glass constructed from flat or prismatic glass may be required for high-pressure boilers. The gauge glass device, which has stood the test of time, is used on the vast majority of boilers and is usually arranged to give a visible range of water level above and below the normal water level.
Since steam boilers are under pressure, differential pressure transmitters (e.g. ABB type 266MST) must be used for level measurement in order to compensate for the vessel's overpressure. To make sure during this differential pressure management that hot steam does not condensate at the colder offset side of the transmitter in an undefined way

Steam boiler water level detection is vital to prevent damage to plant and personnel, Hydrastep's electronic gauging system is the ideal 'fit and forget' solution to overcome the problems associated with unreliable and maintenance-intensive gauge glasses.
PG-60.1: all boilers having a fixed water level (steam and water interface) shall have at least one gauge glass (a transparent device that permits visual determination of the water level). PG-60.1.1: boilers having a maximum allowable working pressure exceeding 400 psi (2800 kPa) shall have two gauge glasses. Instead of one of the two required
