Vane Type Water Flow Indicator (ZSJZ Series)
ZSJZ Water Flow Indicator is a critical element in automatic wet sprinkler systems. It is installed at the branch supply pipe to detect water flow and convert the kinetic energy of water into electrical signal alerts.
Key Features
- Flexible microswitch with high electrical conductivity and long service life
- Built-in adjustable delay circuit (2-60 seconds) to filter out water hammer fluctuations and prevent false alarms
- Supports saddle (saddle-mount), thread, or flanged/grooved installations
- Vane blade flexes smoothly without obstructing the main water channel
