Handheld ultrasonic flowmeter does not need to destroy the pipeline in the measuring process, and the sensor does not contact the measured medium and has no pressure loss. It is suitable for measuring metal pipes, plastic pipes and other pipes with sound transmission materials. Built-in rechargeable battery can work continuously for more than 12 hours. Intelligent on-site printing function ensures the integrity of flow data. The instrument is small in size, light in weight and convenient to carry. The sensor is easy to install, and can be used to measure the sound transmission medium of pipelines of various sizes. In the measuring process, there is no need to destroy the pipeline, stop production, the sensor does not contact with the measured medium, and there is no pressure loss. It is suitable for measuring metal pipes, plastic pipes and other pipes with sound transmission materials. Built-in rechargeable battery can work continuously for more than 12 hours. Intelligent on-site printing function ensures the integrity of flow data.

The embedded Ni-MH rechargeable battery of the handheld ultrasonic flowmeter can work continuously for more than 12 hours when fully charged, and the external power supply needs a charger. The battery charging circuit adopts constant current and constant voltage mode. This method is characterized by fast charging at the beginning and slow charging when the battery is about to be fully charged. During charging, the green light is on, indicating that it has reached 95% of the battery capacity; The red light goes out and the battery is fully charged. Because the charging current becomes smaller and smaller when the battery is nearly fully charged, there will be no overcharge problem, that is to say, the charging process may last for a long time, and the charger can be plugged in all the time during all-weather measurement.

Structure principle of hand-held ultrasonic flowmeter:

1. Ultrasonic flowmeter is mainly composed of ultrasonic generator, ultrasonic receiver, electronic circuit, flow display and accumulation system. Among them, the ultrasonic generator is mainly used to generate ultrasonic waves and emit them into the liquid.

2. The ultrasonic receiver is mainly used to receive ultrasonic waves passing through liquid. After receiving ultrasonic waves, they are amplified and converted by electronic circuits, and then the flow is transmitted to the display screen in the form of electrical signals, and the results are displayed. Cumulative system completes cumulative calculation of flow.

Characteristics of hand-held ultrasonic flowmeter;

1. Multi-pulse technology, digital signal processing technology and error correction technology are adopted, so that the flowmeter is more suitable for the industrial field environment, and the measurement is more convenient, economical and accurate. It can be widely used in petroleum, chemical industry, metallurgy, electric power, water supply and drainage and other fields.

2. The unique digital signal processing technology makes the instrument more stable in measuring signal, strong in anti-interference ability and more accurate in measurement.

3. No mechanical transmission parts, not easy to be damaged, free of maintenance and long in service life.

4. The circuit is more optimized and the integration is high; Low power consumption and high reliability.

5. Intelligent standard signal output, friendly man-machine interface, and multiple secondary signal outputs for you to choose at will.
