Flange Connection Flow Indicator
The flange type water flow indicator has become the preferred choice for industrial and high-rise building fire protection systems due to its advantages of high-pressure sealing, anti vibration, and long service life.
Fujian Haijing Fire Fighting Equipment Co., Ltd. is one of the leading manufacturers and suppliers of flange connection flow indicator in China, also supports customized service. Please feel free to wholesale cheap flange connection flow indicator from our factory.
Products Description
The Waterflow Indicator is used to detect a sustained flow and give signal on wet-pipe sprinkler systems. It includes mechanical time delay feature to reduce the risk of false alarm.
The Flange Type Water Flow Indicator is a key component in automatic sprinkler fire extinguishing systems, mainly used to monitor the water flow status in the pipeline network in real time and send alarm signals to the fire control room when the sprinkler system is started. Its core function is to detect water flow through mechanical or electronic means to ensure the normal operation of the system.
Its core value lies in accurately monitoring water flow and quickly locating fire situations. It is resistant to high pressure, corrosion, and suitable for harsh environments
Improve system reliability.
Typical Application Scenarios
1.Automatic sprinkler fire extinguishing system: installed on partition pipelines to locate the fire area.
2.Industrial circulating water system: monitoring the flow status of cooling water/process water.
3.Water supply and drainage monitoring: flow monitoring of large building water supply network.
core function
Real time monitoring of water flow status
When the water flow velocity in the pipeline is ≥ 0.5m/s, a signal is triggered through mechanical or electronic means
Detectable minimum flow rate from 0.2L/s to 5L/s
Fire alarm linkage
Mechanical: outputting passive dry contact signals through micro switches
Electronic: Output 4-20mA/RS485 and other signals to the fire control host
Typical response time ≤ 3 seconds
Visual status indication
Mechanical pointer/window displays water flow status
Equipped with a manual testing rod, it can simulate water flow actions on site

Q&A
Q: What matching parts are required for flange installation?
A: Required components:
⊙ Paired flange (same pressure rating)
⊙ Sealing gasket (rubber/metal wrapped)
⊙ Bolt and nut
Recommended components:
Expansion joint (compensating for pipeline displacement)
Support bracket (to prevent the valve body from bearing weight)
