liquid level monitoring system Applications
Depending on the regulations, a steam boiler must be equipped with one or more direct and/ or indirect level gauges. With direct level gauges, the liquid level can be seen directly through a glass or mica window. The use of a transparent level gauge with background illumination gives operating staff a clear separation between the water and steam zones even when viewed at a relatively long distance. Bicolour level gauges (black and white or green and red) are very suitable for camera transmission to the measuring station because of their special design and the intense LED illumination. With indirect level gauges, the water level is transmitted by a magnetic system to a display panel on the outside of a pipe.

The presence of moisture in high-pressure natural gas from production wells causes pipelines and associated valves to freeze. High moisture content also leads to the formation of hydrates of the liquid hydrocarbons present, thus causing further difficulties. The moisture content of the gas also adversely affects the calorific value of the gas, thus lowering the quality and value of the product. Moisture is therefore measured at the point of extraction, at export stations, at gas storage locations and in the transmission grid. As natural gas often contains high levels of contaminants, more complex systems are required to maintain instrument performance over prolonged periods and to verify data collected in spot-check moisture analysis.
