Doppler open channel flowmeter

Product Overview

Flow-Dp-2000 Doppler flowmeter is widely used in fields such as water conservancy, environmental protection, urban water supply and drainage. Simple, fast, accurate, reliable, and stable channel and river flow measurement, suitable for various water quality: urban sewage, industrial wastewater, irrigation and drainage, drinking water, seawater, etc.

Product Features

1. It can measure the flow rate, velocity, water level, water temperature, and cross-sectional area of pipelines, channels, and natural rivers;

2. Can provide instantaneous and cumulative flow values;

3. The instrument is equipped with 512M (two months of historical records) data storage, which can be queried through the touch screen for two months of historical records;

4. Communication interface: MODBUS-RTU;

5. Sensors can work for a long time in harsh environments and sewage quality;

6. Environmental conditions: No mechanical rotating parts, no mud blockage or entanglement of water, grass, debris, etc;

7. Sensor power consumption: When measuring flow rate: current<60mA, power consumption<1W;

8. Probe housing can withstand sealing pressure: greater than 4.5 atmospheres, capable of working underwater up to 20 meters;

9. 4.3-inch touch screen display, easy to display and operate;

10. The device adopts a plug and play modular design, fully referencing the technical machine mode, display module CPU、 The independent separation of the motherboard facilitates maintenance and upgrading (changing the previous complete repair and replacement mode, greatly reducing repair costs, and improving work efficiency).
