Water Tank Level Magnetic Float Level Switch With Wireless
Controller
Product Description
UHK magnetic floating ball and float level switch are made up of
reed pipe and magnetic float. It is based on the buoyancy
principle, using the floating ball with magnetic components to
drive the corresponding position of the reed tube to close or
disconnect, so as to realize the detection and control of the high
and low position of the liquid level.
UHK magnetic float and float liquid level switch are equipped with
8 switches for 8 point detection. When the magnetic float ball
level switch works, it has no direct contact with the measured
medium, no mechanical wear and tear on the contacts, and it can
work without external power supply.
Features
1, long life span, stable and reliable operation, easy
installation, almost no maintenance
2, none influence of measured medium in physical and chemical
state. Eg: medium electrical conductivity,
dielectric constants, foam, pressure, temperature, evaporation,
boiling, bubbling effect etc, .
3, choose appropriate material can be used in a variety of bad
media environment with densities ≥ 0.5G/CC ;
4,-interface measurement with two media of different density
control;
5,wide range of application. Pressures from vacuum to PN160
(special up to PN320), temperature -40~+150 ° c;
6,design, explosion-proof, suitable for explosive environments;
7,UHKG controller can be used to control the upper and lower liquid
level.
Operation:
Two control method of one magnetic float level gauge:
1,the upper limit—users select the normally open contact
connection: the machine starts when the liquid level reaches the
controlled upper limit and the node closes.
When the liquid level reaches the controlled lower limit and the
node opens, the machine stops. (eg. When the liquid flows out the
pump);
2,the lower limit—users select the normally closed contact
connection: the machines starts when the liquid level reaches the
controlled lower limit and the node closes.
When the liquid level reaches the controlled upper limit and the
node closes, the machine stops. (eg. When the liquid flows in the
pump);

The magnetic suspension level gauge and the container to be
measured form a communicating device, so that the liquid level
between the container to be measured and the measuring tube body is
equal. When the float in the measuring tube of the liquid level
gauge changes with the measured liquid level, the magnetic body in
the float interacts with the magnetic body in the color code
displayed on the display bar and reverses, so that red means there
is liquid and white means no The purpose of accurately displaying
the liquid level on the spot.
Magnetic levitation pair installed horizontally
A) When the user receives the product, he must carefully check the
product to see if there is any damage during transportation and
whether it is consistent with the order requirements. After
checking, install it correctly in the following order.
B) Float and measuring tube are packed separately. Remove the
bottom flange, make the upper part of the float upward, put the
float into the measuring tube, and install the bottom flange. Then
connect with the container to be measured
C) The magnetic body in the float interacts with the magnet in the
color bar on the display screen, the color code is reversed, red
means liquid, and white means no liquid.
Note: Handle the float carefully to avoid damage; In order not to
affect the read value, all the floats in the display column must be
adjusted to white before installation.
