Liquid Level Controls: Liquid Level Measurement Buyers Guide Directory
In many if the process control industries, liquid level measurement sensors fall into two main types. Point level measurement sensors are used to mark a single discrete liquid height–a preset level condition. Generally, this type of sensor functions as a high alarm, signaling an overfill condition, or as a marker for a low alarm condition. Continuous level sensors are more sophisticated and can provide level monitoring of an entire system. They measure fluid level within a range, rather than at a one point, producing an analog output that directly correlates to the level in the vessel. To create a level management system, the output signal is linked to a process control loop and to a visual indicator. The Level Control and Measurement Directory offers a comprehensive range of liquid level controls, liquid level measurement, level instrumentation and level sensors available from industry leading manufacturers.
