The HY-UHZ liquefied petroleum gas level gauge consists of a body, a flip box (composed of red and white dual color magnetic flip plates), a float, a flange cover, etc., and is used for measuring the level of various liquid containers. It can be used for on-site or remote display and control of liquid level in high-temperature, explosion-proof, anti-corrosion, food and beverage, and other occasions. Suitable for various environments from low temperature to high temperature, vacuum to high pressure, etc., it is an ideal liquid level measurement product for industrial sectors such as petroleum and chemical industry. According to the different installation positions in the container, two forms are provided: side mounted and top mounted. According to different working media, stainless steel and 304, 316, 316L materials are provided, suitable for corrosive media such as acid and alkali.

Structural form of liquefied petroleum gas level gauge

1. Basic type

According to the principle of buoyancy, the float moves up and down in the measuring tube with the rise and fall of the liquid level. The permanent magnet inside the float drives the red and white flip columns to flip 180 ° through coupling. When the liquid level rises, the flip column changes from white to red, and when it falls, it changes from red to white, thus achieving liquid level indication.

2. Electric remote transmission

Install a transmitter on the float level gauge, move the float up and down, and use magnetic coupling to sequentially move the measuring elements inside the guide rod to obtain resistance signal changes, convert them into standard signal outputs of 0-10mA or 4-20mA, and connect them with display instruments or computers to achieve remote transmission.

3. Upper and lower limit switch output

A controller is installed on the liquid level gauge riser at the upper and lower limit positions set by the user. The controller is equipped with a self holding reed switch, which uses a magnetic float to move with the liquid level to trigger an alarm or limit control when the reed switch is activated.

1. Using a float as the measuring element and a magnetic steel driven flip column display, no energy is required.

2. Equipped with upper and lower limit switch outputs, it can achieve remote alarm and limit control.

3. Equipped with a transmitter, remote liquid level indication, detection, and control can be achieved.

4. Compared with traditional glass tube and plate level gauge, it has higher reliability, safety, progressiveness and practicability.

The most significant feature of the magnetic flap level gauge is that the liquid medium is completely isolated from the indicator, making it very safe, reliable, and durable in any situation. Moreover, various models of magnetic flap level gauges are equipped with level alarms and control switches, which can achieve upper and lower limit alarm, control, or interlocking of the liquid level or boundary.

6. Equipped with a static pressure level transmitter or a dry spring resistance level transmitter, the liquid level and boundary signals can be converted into a two-wire 4-20mA standard signal, enabling remote indication, detection, recording, and control.
