Phase modifier rotor packing cooling water flow monitoring device and monitoring method

The invention discloses a phase modifier rotor packing cooling water flow monitoring device and a monitoring method. The device comprises a measuring container and a collection assembly which is used for collecting and conveying phase modifier rotor packing cooling water to the measuring container, wherein the measuring container is connected with a liquid level detection assembly used for measuring the height of the liquid level in the container and a drainage control assembly used for controlling drainage of water in the measuring container. The monitoring method comprises the following steps of: collecting and conveying the cooling water of the rotor packing of the phase modifier to the measuring container, measuring and calculating the flow of water entering the measuring container by adopting a first mode and a second mode, discharging the water in the measuring container, and repeating the monitoring step. The phase modifier rotor packing cooling water flow monitoring device has the advantages of saving
