COMEM - Contactless Liquid Level Indicators Datasheet

Liquids like mineral and silicone oils insulate and cool a transformer. You need to monitor the level of the oil to assure reliable and safe operation of the transformer. Choose our new contactless ultrasonic sensor-based liquid level indicator type CU eOLI and get continuous high accuracy measurement of liquid level in transformer with or without rubber bag. The sensor calculates the distance of the targeted surface in the transformer measuring the ultrasonic wave flight time. The monitors the preset values remotely or choose to visualize the values on-site at men-height through the easy-to-read eViewer dial installed on the transformer wall and decide on the best transformer maintenance schedule. The indicator is equipped with a digital interface for easy connection to smart grid applications and can be integrated into a system through a central control unit. It is compatible with our complete eDevice family and can be connected also with third-party devices.
