Product Description

Lzb-Series Glass Rotor Flowmeter with Alarm Switch
can be used for measure volume flow of liquid or air, example air flow measuring, water flow test, diesel oil flow meter.

Working principle

Rotameter with alarm switch bistable magnetic excitation functions using the magnetron, magnetic float to achieve contacts with the opening and closing. Relays and other components to achieve with their own sound, light alarm needs.

Functions and Applications

BJ01: Limit alarm switch
BJ02: Lower limit alarm switch
BJ01 and BJ02 alarm switch can be at maximum, in the middle, the minimum value of any traffic signals. Alarm switch mounted on sliding rails, select the desired location. When the magnetic float switch position is reached or exceeded, i. e. A signal. At this point the internal contacts open or closed.

Technical parameters

Working pressure: ≤ DC100V or AC100V Working Current: ≤ 0.5A switch, constant current: ≤ DC0.3A interdiction Power: ≤ 10W
Insulation resistance> 10 Working temperature: 0 º C - +55 º C Protection class: IP65 lag (open or closed position) ≤ 4mm


1 installation, try to stay away from the external magnetic interference devices, such as large motors.
2 fluid medium can not contain ferromagnetic impurities
3 should be installed in the pipe vibration, in order to prevent malfunction of the switch contacts.
