The waterflow indicator is a visual mirror instrument valve. It is suitable for oil, chemical, chemical, chemical fiber, medicine, food, power plant, pump and other industrial production pipelines. It can observe the turbidity of liquid, gas, steam and other media at any time through the windowThe flow speed response is one of the pipeline accessories that ensure normal production and ensure the quality of the product.The connection method includes a thread; flange type; welding.

The role of the water current indicator
The main application of the water flow indicator is to apply the water extinguishing system of fire protection, and the water flow indicator plays an important role in the automatic water extinguishing system.Some of it are installed on the main water supply pipe, some are installed on the horizontal rod water pipe. It can give the water flow signal of a water flow in a partition during the water extinguishing system.If the control box is controlled, the corresponding system will be given after reaching the electrical control box, so that the control switch of the fire water pump can be launched, and the role of detection and instructions can be achieved.
How to wiring the water current indicator
The water flow indicator and signal butterfly valve are connected to the alarm system through the switch volume of the water flow and the signal butterfly valve through the input module, and the input module only needs to alarm bus, so you can only put a group of alarm signal bus (red and blueThe twisted line can be).
Principle of water current indicator
The structure and principle of water flow indicator: somewhere, the system is turned on, the nozzle is sprayed, the water flows in the pipe, the leaves in the impact of the water flow indicator are shifted to the direction of the water, the action rod is squeezed by the super small electrical switch, the delay circuit is delayed circuitConnect, the leaves are still not available after the delay set time, and the electrical contact is closed to give an electric contact signal.The water current stops the time and the action rod is reset.A certain period of time issuing alarm signal is a misunderstanding that may cause the water pressure fluctuations in the instantaneous water pressure.
