Detailed Description
In order to express the present invention more clearly, the following description is made with reference to the accompanying drawings.
As shown in fig. 1, the present embodiment is composed of 4 parts, which are a detection unit, a data unit 20, a wireless communication unit 22 and a power supply unit 21.
As shown in fig. 1 and 2, the detection unit, which detects the water level and the water flow rate, is composed of a water level sensor 10 and a flow rate sensor 11. The water level sensor converts static pressure into an electric signal based on the principle that the measured static pressure of liquid is proportional to the height of the liquid, and then converts the electric signal into a standard electric signal (4-20 mA/1-5 VDC) through temperature compensation and linear correction. During installation, the water level sensor is directly thrown into the pipeline, and the selected range is 0-2 meters.
The water level sensor 10 in this embodiment is a drop-in liquid level sensor, and the sensing component of the flow rate sensor is a rotary flowmeter 100, wherein the rotary flowmeter has reliable performance and simple installation, and has the characteristics of high repetition degree of output signals, firm structure and no or little need of maintenance. The sine wave frequency signal is output, and the passive flow indicator can be driven. The dynamic flow velocity measuring range is 0.3-6 m/s, and the liquid flow under the low-pressure system environment can be measured. Adopt buoy type installation during the sensor unit installation, can float from top to bottom along with the liquid level, detect water upper strata flow, still set up rudder 201 in buoy body below simultaneously for the automatic alignment flow direction, buoy body 200 passes through pull wire 102 to be fixed at municipal drainage pipe or irrigation canals and ditches top, prevents to be washed away by rivers, and runner flowmeter 100's data line 101 is connected to data unit 20.
