1.Introduction
1.1 Measuring principle
The ultrasonic Doppler flowmeter is a host that collects the flow velocity, water level and temperature of the ultrasonic Doppler flowmeter through RS485, and inputs various channel parameters according to the actual situation on site. The water flow area S (㎡) is calculated using the channel parameters and the collected water level H (m), and the instantaneous flow rate (Q=V*S) is calculated by multiplying the water flow area and the flow velocity V (m/s), and the cumulative flow rate is calculated by multiplying the flow rate by the cumulative time.
From this we can know:Q=V*S
Instantaneous flow rate * time difference = cumulative flow rate
1.2 Composition
KDF1000 series flow meter is a product that measures the velocity and flow of water in natural waters, channels, or pipelines.
The flow meter is divided into two parts: the sensor and the host, which are connected by a cable.
It can measure the speed and flow of water in channels and rivers, and the water level is more than 20 cm higher than the top of the sensor.
It can measure the speed and flow of water in pipes and culverts. The water level must be more than 20 cm higher than the top of the sensor, and the inner diameter of the pipe must be ≥ 500 mm.
