Low water alarm - For safe boiler operation, the low water alarm ensures that the combustion of fuel does not continue if the water level in the boiler has dropped to, or below a predetermined level. For automatically controlled steam boilers, national standards usually call for two independent low level alarms, to ensure safety.
Methods of Detecting Water Level in Steam Boilers | Spirax
Conventional shell boilers are normally operated with the TDS in the range of 2 000 ppm for very small boilers, and up to 3 500 ppm for larger boilers, provided the: Boiler is operating near to its design pressure. Steam load conditions are not too severe. Other boiler water conditions are correctly controlled.
Jun 09, 2018 · State-of-the-art turbidity meters are beginning to be installed in rivers to provide an instantaneous turbidity reading. A long device is lowered into the water and at the end is a turbidity sensor. It reads turbidity in the river by shining a light into the water and reading how much light is reflected back to the sensor.
