Below is a list of Ultrasonic Flow Meters manufacturers from Burbank, California. Ultrasonic flow meters are flow meters that use sound to determine flow rate. An ultrasonic flow meter is a volumetric flow meter that requires particulates or bubbles in the flow. Ultrasonic flow meters are available in both single and dual-sensor versions though models using two sensors are more common and may be more accurate. Ultrasonic flow meters are ideal for wastewater applications or any dirty liquids that are conductive or water-based.
