Magnetic level gauges – A magnetic level gauge is used to control the level of fluids. The gauges operate under Archimedes Principle, which states that any object submerged in a fluid experiences the same buoyant force as the weight of the liquid displaced.
Reflex level gauges – A reflex level gauge is used to detect level in a vessel or container. It operates by using the dissimilarity in the index of refraction between fluids and vapors. They are usually made of carbon or stainless steel, which provides the durability needed to work in a temperature and pressure range up to 400°C and 400 bar respectively.
Transparent level gauge – Transparent level gauges are very similar to reflex level gauges. They consist of two transparent glasses which are integrated with the liquid cavities on both sides.
Bi-color level gauge – Bi-color level gauges are used to measure the media level in a boiler. The gauge uses high quality mica sheets to guard against the wet steam generated in a boiler drum.
Tubular level gauge – Tubular level gauges are best used in low pressure, non-toxic liquid level measuring applications. They detect and report process level though direct communications.
