Working Principle

Float switch is using microswitch to be contact elements.When the liquid level rises to the float place, angle of floats place will be changed by the liquid level. When it reaches an certain angle, there will be ON or OFF contact signal output at the switches.

Installation    

Basic Parameters

*Water pump below 220V 1KW, can use directly.  

*Water pump over 1KW, needs A.C. contractor or relay.*

Q: The new magnetic flap liquid level gauge can't show liquid level?
A: 1.check whether there is block in by pass pipe 2.check the the density of medium 3.check whether the float ball is stucked by float ball.

Q: The longest length of magnetic flap liquide level gauge?
A: the length is customized,but in order to be convenient for transport,if the length is over 6m,we recommend

Q: If the float ball is installed at the wrong opposite direction,what's the influence?
A: reading level will be higher than true level,usually higher by length of floatball-70mm

Q: What's installation details of magnetic flap liquid level gauge ?
A: 1.before installation,check specification with label plate. 2.There shouldn't magnetic field within 400m

Q: There is problem in output signal 4--20mA?
A: 1.Check working power supply 2.check wiring 3,check load resistance 4.verify measuring range,zero point

Q: what's specification we need to know before purchasing magnetic flap liquid level gauge?
A: medium density,working temperature,working pressure,material,flange center to center distance,flange standard,whether need 4--20mA output signal;wether need level alarm
