Description
Overview
Asset Track Pro Ultrasonic Liquid Flow Meter uses the principle of “area velocity method” to measure the open channel flow. The system has a built-in open channel flow model, which uses the single-point flow velocity method combined with hydrological fluids to deduce the average flow velocity of the river channel through the single-point flow velocity and calculates the water flow in combination with the water level and the cross-sectional area of the water flow.
Features
- The measurement range is large (velocity range is 0.01-10m/s), and the flow measurement is not affected by the return water on the tributary surface
- The structural design of the flow rate sensor conforms to fluid mechanics, with a small size and convenient installation. The standard channel can be installed directly without modification, and the construction cost is low
- The measurement signal is stable and less affected by the channel water flow
- It can display the channel liquid level, flow rate, instantaneous flow and cumulative flow at the same time
- EEPROM is used to store the accumulated flow, and the data can be stored for a long time after power failure
- Large-screen dot matrix display, not only in Chinese, but also with graphics, which is convenient for operation and flow analysis
- Optional real-time display of flow velocity curve and graphic software, which is convenient for analysis and research of water flow
- With RS485 communication port, it can realize remote data transmission
- Portable with data storage function, easy to analyze the measurement situation
