I. Description:

ZSJZ-I-1 water flow indicator is welded type structure and used for DN50~150mm. Water flow indicator, which is the main part of the automatic sprinkler system. It pushes vane utilizing the flow of water in the deluge network to contact slight switch. Thus it converts current signal into electrical signal. It connects with controller to start automatic fire alarm system. It is used for checking the operation of automatic deluge system and the region of the fire.

It is suitable for wet, dry, pre-act, circulation and foam deluge system.

II. Characteristics:

1. It has compact structure and beautiful appearance. It can adjust its sensitivity outside the wiring box without any tools.

2. It adopts stainless steel connection and convenient for construction.

3. It has complete set of specifications: DN50-DN200

4. Its connecting methods: welded type.

III. Technical Parameters:

1. Applied Caliber: 50 --200mm

2. Rated Working Pressure: 1.2MPa

3. Sealed Test: 2.4MPa water pressure for 5min without leakage

4. Operation Flux: 15 L/min ~37.5L/min. Adjust from outside

5. Switch Capacity: AC220V，5A；DC24V，3A

6. Contact Output: Normally open: C--NC; Normally close: C--NO
7. Can supply normally open and normally close contact for selection.
IV. Others:

1. When installing, it should assure the direction of medium in the pipeline is the same as the arrow direction of water flow indicator.

2. When installing, it should assure the vane does not contact with the inside wall of the pipeline. Vane and driving rod should move flexible.

3. After finishing the φ42mm hole, it should remove the bur.

4. When installing, the electrical wiring box of the water flow indicator should be upright.

5. Two fixing bolts should be symmetrical.
