LZB Water Air Glass Flow Meter with Alarm

This Series of flowmeters is made of SS304. There are female Screw threads. Flange Connection and Tri-clamp connection for choice. It is featured in nice looking and low weight.

Switch on/ off is actually magnetic float contact open/ close after magnetron bistable exciting.Alarm sound and light are based on the switch position of on/ off linked to relays among other parts and elements.

Product Description

■Introduce

1) Philosophy
2) Switch on/ off is actually magnetic float contact open/ close after magnetron bistable exciting.Alarm sound and light are based on the switch position of on/ off linked to relays among other parts and elements.
3) Functions and Applications
4) BJ01: High Alarm Limit Switch (HA) BJ02:Low Alarm Limit Switch(LA), Both the switches of BJ02 are to send relevant signals at maximum, middle and minimum flow. The switches are mounted on certain selected position of rail and whenever magnetic float reaches or passes the switch level, signals will be sent out for internal contact actuation of either opening or closing.
5) Technical Parameter
6) Rated Voltage: max DC24/AC24 Rated Amperage: max 0.3A Steady Current at Switches Opening or Closing: max DC 0.1A Interruption Capacity: ≤10W Insulation Impedance: > 10^9 Ω Working Temperature: 0℃-+55℃ Protection Grading: IP65 Displacement(position on or off): ≤4mm
7) Precautions
8) Keep off from ambient magnetic disturbance during mounting e.g. large motors etc;
9) Flow media should be free from ferromagnetic foreign matters;
10) Ensure pipes or tubes to be mounted with the flowmeters free from any potential vibration in case switch contact actuates accidentally
