Installation Instructions

The flowmeter consists of two parts: a flow velocity measurement radar and a water level measurement radar. Among them, the flowmeter measures the Doppler of the water flow Frequency shift is used to calculate the flow velocity on the water surface; Liquid level measurement radar is similar to flow rate measurement radar in that it calculates the flight time of electromagnetic waves And calculate the distance between the radar and the water surface. The flowmeter measures the flow velocity and liquid level, combined with the actual cross-section of the river to be measured based on the input Based on the characteristics of the river, estimate the velocity distribution on the river section and use the corresponding dataThe empirical model calculates the river flow rate.

When installing a radar flowmeter, try to install it in reverse flow. When installed in reverse flow, the measurement signal is clearer and more accurate than when installed in parallel flow. When the measured water flow is only in reverse flow, the "measuring liquid flow direction" of the Jiang measurement flow rate radar is set to "reverse flow". This installation and setting not only make the measurement signal clearer and more accurate, but also avoid interference from rain, snow, and other factors at a high speed limit.
