The hand held flow meter is a battery-powered ultrasonic flow meter with the capability of a full-size flow meter. It is carefully designed for portability and ease of use. 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.); sewage; oil (crude oil, lubricating oil, diesel oil, fuel oil, etc.); chemicals (alcohol, acids, etc.); waste; beverage and liquid food, solvents and other liquids. 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. The hand held flow meter utilizes our proprietary technologies such as advanced signal processing, low-voltage transmitting, small signal receiving with self-adapting. It also incorporates the latest surface-mounting semiconductors and mini PCB design techniques. The built-in rechargeable Ni-H 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. EUROMAG INTERNATIONAL EUROSONIC 2000 HH is the state of the art palm Transit Time Ultrasonic Flowmeter. It comes with a complete kit of parts that allow the operator to carry out accurate flow measurements in every possible conditions.
Transit Time Flow Measurement
The transit time technique uses a pair of transducers each of them sending and receiving a ultrasonic signal through the fluid. When the fluid is flowing, signal transit time in downstream direction is shorter than in upstream direction; the difference between these transit times is proportional to the fluid velocity. EUROSONIC 2000 HH measures accurately this value and correlates it to the flow rate through the inner pipe diameter.
EUROSONIC 2000 HH uses non wetted clamp on transducers for ease of installation and removal. Clamp on transducers are magnetically or mechanically installed on the outer surface of the pipe where the flow has to be measured.
