Clamp-on Ultrasonic Flowmeter with DSP Technology

The MUL-310 is a "Time of flight" type Ultrasonic Flowmeter for liquids. Since the ultrasonic receiver required for the flow measurement is installed by the clamp-on system on the exterior of the pipe, it does not contact the measuring fluid at all, and also there are no concerns about particle generation or contamination of metallic ions in the fluid as it is truly non-invasive. It is suitable for the flow rate measurement of pure water and ultra pure water for the semiconductor industry. The resistance to bubble interference in the signal has been sharply improved by the new signal process method "DSP"(Digital Signal Processor). If bubbles are contained in the fluid, the transmission of the ultrasonic signal is impeded and signal recognition becomes difficult resulting in a loss of signal. Digital Signal Processing technology has been adopted for MUL-310, and even if the bubbles are contained in the fluid, the stable measurement of signal can be achieved. This product does not have limitations in terms of volume of bubbles by air volume being less than 10%. (It is not possible to recognize the signal in case of fluid streams with excessive bubbles)
