Products Description
The threaded water flow indicator is a device used to monitor the flow status of liquid in pipelines. It is connected to the pipeline system through a threaded interface and is widely used in fields such as fire protection, industry, and water supply. The following are its core features and brief introduction:
1. Basic functions
Water flow monitoring: Real time detection of the flow status (flowing/stationary) of liquids (such as water, oil, etc.) in pipelines, and output through mechanical or electrical signals.
Alarm triggering: Often linked with the fire protection system, an alarm is triggered when the water flow starts, indicating the system's operation (such as the sprinkler system starting).
2. Main features
Threaded connection: Designed with internal or external threads, it can be directly screwed into the pipeline for easy installation and good sealing.
Visual indication: Some models are equipped with mechanical pointers or windows, which can intuitively display the water flow status.
Electrical output: Optional switch signal (normally open/normally closed contacts) or analog signal, compatible with automation control systems.
Pressure and corrosion resistance: The material is mostly brass, stainless steel or engineering plastic, suitable for high pressure, high temperature or corrosive media.
core function
Typical applications
Fire protection system: installed in the sprinkler network for fire alarm linkage.
Industrial process: Monitor the flow status of cooling water, chemical liquids, etc.
Water supply/irrigation: detect pump operation or pipeline leaks.
Installation and maintenance
Installation position: Usually installed in horizontal or vertical pipe sections to ensure accurate detection of full pipe flow.
Maintenance: Regularly check the thread sealing to prevent leakage; Clean the impeller or sensor to avoid blockage
Industry application expansion
Fire Protection System
Installation example: End of sprinkler branch pipe in each fire compartment.
Industrial sector
Cooling tower monitoring: detect whether the cooling water circulation is interrupted to prevent equipment overheating.
Chemical process: Acid and alkali resistant models are used for corrosive media.
Agriculture/Smart Water Management
Drip irrigation system: detect blockages or ruptures in branch pipes, and close the linked solenoid valve.
Partition metering: Cooperate with flow meters to achieve pipeline leakage analysis.

Q&A
Q: Do threaded water flow indicators for firefighting need to be regularly inspected? What is the frequency?
A: Mandatory requirement:
National standard regulation: Simulate water flow testing signal function every quarter, and conduct system wide linkage testing every year.
Maintenance content:
Manually rotate the impeller to check for any jamming.
Clean the impurities in the filter.
Test the conductivity of electrical contacts.
