The hand held Ultrasonic Flow Meter is a battery-powered ultrasonic flow meter with the capability of a full-size flow meter. The hand held flow meter is based on clamp-on transit-time flow measurement principle. It measures the flow rate of liquid in a pipe from outside of the pipe by using a pair of ultrasonic transducers. In general, the liquid should be full in the pipe, and should contain very little particles or bubbles. Examples of applicable liquids are water (hot water, chill water, city water, sea water, etc). Due to the nature of clamp-on technique, the transducer installation is simple and no special skills or tools are required. Besides, there is no pressure drop, no moving parts, no leaks and no contamination.
Battery can work continuously for more than 10 hours without recharge. The hand held flow meter has also a built-in data-logger, which allows storage of 2,000 lines of data. The stored information can be downloaded to a PC through its RS232 connection port. Temperature Range 0oC to 160oC 1/2" to 240" pipe diameter can be measured with the help of different transducers.
