Blending or mixing tanks are often used in many industry applications, for example in the chemical industry. Both for mixing fluids and solids into fluids, often at ambient conditions but sometimes at elevated temperature to enhance dissolving. Usually, the blending or mixing tank is equipped with an agitator. Level measurement is needed to monitor and control additions and prevent overfill. Some of the challenges blending of various types of chemicals can present are presence of corrosive media, condensation, foam and risk of media build-up if contents are viscous or sticky. Reliable level measurement technology is key to have high level of quality control and reliable overfill prevention or underfill / run-dry prevention.
Emerson's new non-contacting radar portfolio together with its point level detection portfolio provide ideal solutions to meet the diverse needs of blending and mixing tanks in the industry.
The Rosemount 2120 Level Switch provides easy to install, reliable level detection and control. 3 rdparty IEC61508 (SIL2) safety and hygienic certification with choice of outputs makes it suitable for a wide range of applications. It has no moving parts, needs no calibration and is virtually unaffected by process conditions. Adjustable switching delay prevents false switching in turbulent applications. Understand what is going on with your process- the visible heartbeat LED provides device status and health, and magnetic test point provides an easy-to-use functional test.
