Advantages:
1. Ultrasonic flow meters can be installed outside of the pipe and do not require contact with fluid, so there is no pressure loss. The cost of instruments is basically independent of the diameter of the tested pipeline; External clamp installation without the need for pipe cutting.
2. The applicable range of pipe diameter ranges from 2cm to 6m, and can be used in open channels, underground channels, and rivers with a width of 500m;
3. The flow measurement accuracy of ultrasonic flow meters is almost unaffected by the temperature, pressure, viscosity, density, and other parameters of the measured fluid. They can also be made into non-contact and portable flow meters, which can solve the flow measurement problems of strong corrosive, non-conductive, radioactive, flammable, and explosive media that are difficult to measure for other types of flow meters;
4. The adaptability of ultrasonic flow meters is also unparalleled by other instruments.
5. Low-power design， ultrasonic technology provides the possibility for developing low-power ultrasonic flow meters. This characteristic plays an important role in ultrasonic water meters and ultrasonic heat meters. Built-in 3.6V battery, capable of operating for 5-6 years.
Features:
- High accuracy, generally up to ±1%R, ±0.5%R, high precision type up to ±0.2%R; (R refers to reading error)
- Good repeatability, short-term repeatability can reach 0.05%~0.2%. Because of the good repeatability, if it is calibrated frequently or online, it can obtain extremely high accuracy. It is the preferred flow meter in trade settlement.
- Output pulse frequency signal, suitable for total quantity measurement and connection with computer, no zero drift, anti-interference;
- Original pulse frequency range (10Hz~1.5KH), strong signal resolution
- Maximum width ratio, 10:1~20:1
- Suitable for high-pressure measurement, no holes need to be opened on the meter body, and it is easy to make a high-pressure meter; There are many types of special sensors, which can be designed into various special sensors according to the special needs of users, such as low-temperature type, bidirectional type, downhole type, and sand mixing type
- It can be made into an insertion type. Suitable for large-caliber measurement, small pressure loss, low price, can be continuously removed, easy to install and maintain, compact and light structure, easy to install and maintain, large flow capacity
