1. Performance characteristics of UHZ stainless steel magnetic float level gauge

The UHZ type magnetic float level gauge is a measuring instrument which reflects the measured liquid level or interface with magnetic float as sensing element and magnetic coupling effect between magnetic float and magnetic body in display color column. The UHZ type magnetic float level meter applies the principle of connecting pipe to ensure that the liquid level between the measured container and the measuring tube is equal. When the float in the measuring tube is equal to the measured liquid level, the magnetic body in the float is combined with the magnetic body lotus root in the display color column on the display panel to make the color column turn over, and the white color indicates no liquid, and the red is expressed as liquid, so as to display the liquid level in situ. The magnetic float level gauge displayed on the spot has the advantages of showing intuitionistic, eye-catching, wide viewing angle, compact and reasonable structure, safety and reliability, no "running, running, dripping, leaking" phenomenon, small maintenance quantity and low maintenance cost, and its indicating function does not need additional power supply. Even if the power supply fails, the liquid level observation will not be affected, and it is an ideal liquid level detecting instrument. The UHC type magnetic float level gauge is a measuring instrument which reflects the measured liquid level or interface with magnetic float as sensing element and magnetic coupling effect between magnetic float and magnetic body in display color column. The UHC type magnetic float level meter applies the principle of connecting pipe to ensure that the liquid level between the measured container and the measuring tube is equal.

The whole process has no blind area. It shows striking, intuitive reading and large measuring range. In particular, the field instruction part is superior to high temperature, high pressure, high viscosity, toxic, harmful and strong corrosive media because it is not directly contacted with liquid medium. Therefore, it is more reliable, safe, advanced and practical than traditional glass tube and plate type liquid level gauge. The main features of the UHZ series stainless steel magnetic float level gauge are:

1, strong sealing, not easy to permeate. This series of products are treated with special interface, which is more suitable for high permeability applications such as liquid ammonia.

2, high temperature resistance and high pressure capability. This series of products can be 600 25MPa at a large temperature, and the maximum pressure can reach up to

3. Corrosion resistance. This series of products adopts the new stainless steel lined PTFE process, so that the product has strong anticorrosive capability.

4. It can be used at low temperature. This series of products adopts special jacket technology, and it can be handled at 200 degrees below zero.

5. Strong signal transmission capability. The output of this product can be switched and analog, and can be carried with HART protocol.

Two. The working principle of stainless steel magnetic float level gauge.

The liquid level meter is composed of a connecting device, a main tube, a magnetic float, a field sign, and a binding liquid level transmitter or a liquid level switch.Native product

The basic principle of product utilization is the Archimedes principle (buoyancy principle) and the characteristics of magnetic charge repulsion and heterosexual attraction. When the magnetic float in the main pipe follows

When the liquid level rises or descends, the magnetic float is driven to turn over by magnetic coupling to realize the in-situ observation and remote signal display.

Three. Applicable scope of stainless steel magnetic float level gauge.

Because this product line is longer, it can cover most occasions from -200 to 600 C and from normal pressure to 25MPa. Stainless steel.

For example, UHZ-C0x type; top mounted type, such as UHZ-D0x type; anti-corrosion type, such as UHZ-DFx; sanitary grade, such as UHZ-W0x, jacket.

Anti freezing type, for example, UHZ-xxxJ1 to UHZ-xxxJ3, there are sling type, such as UHZ DS1 type, with bypass pipe type installation, such as UHZ-Cxxa/ B type.

Five. Installation and commissioning

1, UHZ series products have been tested by our company's strict pressure test and simulation operation. Zero has been moved to the actual zero position, and the user can install it directly.  

2, installation should pay attention to the main pipe must not enter the magnetic impurity, so as not to affect the floating ball and display board magnetic coupling performance.
