Magnetically controlled liquid level gauge type UHF

The product line UHF is used wherever fluid level has to be monitored, indicated, and controlled in a reliable way, especially with corrosive, toxic and inflammable fluids.

The UHF level indicators offer a reliable, accident-free and maintenancefree usage, through a simple and break-resistant construction at a maximum process pressure of 64 bar and a temperature range from –40 through 350 °C. The fluid level is indicated directly with a separation of the measurement and indication area.

The magnetic transfer of the fluid level from the tank to the indicator is continuous and vibration resistant, even in the case of fast changing levels.

It is possible to mount the indication rail in any position on the pipe diameter. There is no corrosion of the indication system. The UHF instruments may be used in open or closed vessels. A definite level measurement without any power supply is guaranteed due to a continuous rotation of the wafers, even if a power loss in the plant occurs.

Functional principle:

A float chamber is connected to the tank, and following the law of communicating tubes, the level in the float chamber is equal to the level of the tank. The float (3) follows the fluid level and transmits its movements contact-free to the indication rail (4) mounted on the outside. The float has a special magnet, which rotates the wafers by 180° as it passes them. The result is a clearly defined level indication, with the level shown in a continuous red stripe strongly contrasted to the white above. At increasing levels the color of the wafer changes from white to red and vice versa.

The indication rail and the wafers are made of ABS so that there will never be a problem of

corrosion in humid and aggressive atmosphere. Each wafer has a permanent magnet, that is why the indicator is shock proof.

All models are available with electronic alarms, that can be mounted at any position during operation of the system, which renders possible an optimal definition of the min. and max. data points.

UHF-DQ Float level transmitter

UHF-DQ series magnetic float level gauge wild apply in the constant measurement and indication of

Liquid level in the storage tank,pool,water tank of industrial production process.

Measuring principle:

The resistance chain with the reed contacts are built in a pipe made of Stainless Steel. This so-called “Reed-chain” is mounted on the float chamber with tube clamps. According to the movement of the float, the float magnet closes one reed contact which produces a resistance proportional to the height of the liquid in the tank. You get a near-analogous output signal, with a resolution of about 10 mm, 20mm, or 5mm.

Then the reed chain with an R/I measurement transducer can be changed without interrupting the operation. To change the level to 4~20mA proportional.

The resistance chain receives it’s power supply from the transmitter. The 4...20 mA transmitter output signal can be transferred to an indicator or can be used to drive alarm contacts.
