The measurement of material levels in storage tanks is critical in many industrial processes to economically track inventory while ensuring the safety of workers, equipment and the environment. Level sensors detect and measure the level of a medium in silos, storage tanks, bins or other types of vessels. Common technologies such as radar or ultrasonic are tailored to the specific characteristics of the substances they measure and the conditions under which they operate, but these have significant drawbacks in reliability and safety. A safe and reliable method for level detection is based on the gravimetric principle, which allows sensors to be located outside the tank.
Measure any material: Think outside the tank
Placing sensors outside the tank ensures that effects such as sidewall adhesion, dust, foam or heel do not distort your measurement. This provides real-time readings that you can trust, irrespective of material properties. Additionally, gravimetric level detectors prevent inaccurate measurements due to bridging, caking and ratholing caused by material properties like cohesion, particle size distribution, and vessel geometry. They are also protected from high temperatures, vibration, radiation and contamination that frequently damage sensors placed above or inside the tank. With technology that always works regardless of environmental conditions or material, sensor selection couldn’t be easier.
