Armoured level gauge: Armored level gages are used in a variety of applications, such as in petrochemical refineries and chemical plants. They work well in high-pressure environments, coming in a variety of PSI ratings up to 4000 PSI. They are available with transparent and reflex gauge glasses.
Tubular level gauge: Tubular gauges come with a clear or red line Borosilicate (Pyrex) to help improve visibility and measurement of clear fluids. They are often used in low-pressure applications up to 600 psi. Normally, they are recommended for use with oils and petrochemical liquids as opposed to water or steam as there is a possibility of the gauge’s steel valves developing rust or corrosion. However, the tubular gauges sold at McRae Engineering have automatic valves made with corrosion-resistant ball checks and stainless steel valves.
Magnetic type level gauge: For this type of level gauge, the chamber is constructed of non‐magnetic materials, with its float engineered and located inside the chamber. It is sized and weighed to the specific gravity of the process fluid to be measured. The float contains a 360° magnetic assembly, generating a strong uniform magnetic circuit. The float will move according to the changes in the liquid level, allowing for precise measurements.
As you can see, different types of level gauges work differently to suit different applications.
