KDF1100 Wall-mounted Ultrasonic Doppler Flow Meter
1.Introduction
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
