The FCT type flow switch can easily set the flow alarm node, uncheck the protective thread, and adjust the bottom knowledge with a threaded knifeSet the flow alarm point. For flow switches with output forms of PNP, NPN, and relays, the meaning of their LED indicators is as follows: - Red light on, flow rate lower than setspot (Transformer not conducting/relay not acting) - Yes Low light on, Flow rate equal to or higher than setspot (Transformer conduct/relay action) - The flow rate exceeds the setting when the yellow and green lights are onspotDegree of illumination (green light 1, 2, 3, or 4 lit together with yellow light)

Knowledge extension:

How can the fire flow switch directly monitor the water flow speed in the fire water pipe circuit?

1. What flow switch should I choose?

First, we need to determine which flow switch is better to use in the fire water pipe circuit? Based on our over ten years of experience, adjustable electronic flow switches - BL-FRE with scale adjustable electronic piston flow switches - should generally be used in fire water pipeline circuits

2. Why choose an electronic piston flow switch with adjustable scale?

The electronic piston flow switch with adjustable scale is required with a sturdy body, connection section, magnet, and adjustable scale plates for different process ranges A piston with an internal magnet is installed on the internal fluid channel When the water flow rate in the pipeline is greater than the set flow rate, the magnetic core generates displays under the action of water flow and drives the magnetic source to generate magnetic control effect, causing the sensor to output a ^ 1 ^ ^ ^ switch signal This signal is input to the equipment control system, and after power amplification, the purpose of water flow control is achieved When the water flow rate in the pipeline is less than the set flow rate, the magnetic core drives the magnetic source back to its position under the rust of the reset spring, causing the sensor to output a ^ ^ 0 ^ ^ switch signal and stop the system's operation

3. What are the main applications of electronic piston flow switches with adjustable scales?

This series of flow switches is used to monitor the flow rate of the fluid in the fire water pipe circuit When the flow is lower than the set value, the on off electronic alarm signal will be sent to the remote control panel In addition, they are often used in circulation equipment, fuel or water outlets, oil or gas systems and their cooling circuits, heating pumps, welding machines, heaters, transformers, heat exchanges, compressors, food, chemical, and pharmaceutical industries
