Ultrasonic Liquid Level A-ULS

Liquid Level A-ULS

Above Installation

The A-ULS are innovative ultrasonic liquid level sensor families that replace float, conductance and pressure sensors but “non-contact” with dirty, sticky and scaling media in small, medium and large capacity tanks.
Applied in chemical, water and wastewater applications, these general purpose non-contact sensors are available with single and multi-function capabilities including continuous level measurement, switching and control.
