Magnetic float level gaugeintroduce
Suitable for the liquid level measurement of open, closed, and underground storage tanks of various containers such as towers, tanks, tanks, and pools,
It can convert the changes in the measured liquid level into a standard current signal of 4-20mA output, enabling remote monitoring of the liquid level.
principle
It mainly consists of five parts: magnetic levitation ball, sensor, transmitter, main body tube, and installation flange. When the magnetic levitation ball changes with the liquid level of the measured medium
When floating up and down, the magnetic component inside the floating ball attracts a reed switch at a corresponding position inside the sensor. Make the total resistance (or voltage) of the sensor increase
Generate corresponding changes, and then convert the changes in resistance (or voltage) into a standard current signal output of 4-20mA DC by the transmitter
To be used in conjunction with various display devices that can input 4-20mmA.DC signals or enter computer systems to monitor liquid levels. at the same time
Secondary instruments (XMT intelligent digital display) can be used to set upper and lower limit alarms, achieving positional control of the liquid level or other regulators to form the liquid level
Constant value regulation system, achieving continuous adjustment of liquid level.In addition to the above functions, the UQK-2 model is also equipped with a 1.5-level 45C3-A meter head, which can be directly connected
Indicate the liquid level position on site.

Note: 1. H0... is the installation dead zone, which is determined by the user or designer based on the on-site working conditions;
2. H1... is the structural dead zone; （h1=15mm）
3. H2... magnetic float dead zone, when the specific gravity of the medium is 1, h2=60mm
4. L0=h0+h1+h2, which is the measurement dead zone after the instrument is installed, that is, the area that the instrument cannot measure
Installation method of magnetic float level gauge
(1) Install the floating ball on the main pipe, install the baffle at the bottom of the main pipe, and secure it with a small grid.
(2) Place the main body into the container, install the flange and secure the container flange with encrypted sealing gasket.
(3) Open the junction box cover, connect the lead wires, be careful not to connect the positive and negative poles incorrectly, and cover the box cover
And tighten the screw to fix the lead wire.
1. The installation position should be far away from the water inlet, otherwise the switch may cause misoperation due to fluctuations in the water inlet.
If the switch device is installed on the concrete pool wall, an L-shaped angle steel bracket can be added.
If the switch device is located in the mixing area, anti wave tubes or anti wave baffles can be installed.
4. Choose a flange connection pipe with an inner diameter greater than the diameter of the float.
5. It is recommended to use a Φ 8mm multi-core cable for wiring.
6. The load of the controlled circuit must match the contact capacity of the float switch.
7. The specific gravity of the tested liquid must be greater than that of the float.
8. The action point of the floating ball has been adjusted according to the customer's order requirements at the factory. Please do not adjust the position of the floating ball arbitrarily.
