The handheld 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 handheld flow meter is based on the clamp-on transit-time flow measurement principle. It measures the flow rate of liquid in a pipe from the 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 few particles or bubbles. Examples of applicable liquids are water (hot water, chill water, city water, seawater, 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 the 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 handheld flow meter utilizes our proprietary technologies such as advanced signal processing, low-voltage transmitting, small-signal receiving with self-adapting, and etc.
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 a recharge.
The handheld 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. The handheld flow meter also provides digital output such as frequency output or pulsed totalizer output.
