UZC-A04F Liquid Gas Magnetic Level Gauge

UZC-A04F series products are suitable for liquid measurement of easily vaporized media in pressure vessels, especially for liquid level measurement of liquefied gas, liquid ammonia, propylene, and other media. For this special medium that is prone to vaporization, a gear lever is selected to divide the main conduit of the level gauge into a vaporization chamber and a measurement chamber. When the liquefied gas inside the level gauge is affected by temperature and vaporizes internally, bubbles will rise up along the vaporization chamber without entering the measurement chamber and affecting the operation of the magnetic float. This effectively prevents the magnetic float from jumping due to bubbles, and the product performance is stable and reliable. The entire measurement process has no blind spots, an eye-catching display, intuitive readings, and a wide measurement range. It can be used in conjunction with XG/UQZ-08 bundled remote transmitters to output 4-20mA remote signals. It can be equipped with upper and lower limit liquid level alarm switches to achieve upper and lower limit liquid level alarm and control, and realize remote detection, indication, and control.

Product Features:
1. Low-temperature resistance and adaptation to liquid gases: Specifically designed for low-temperature liquid media such as liquid nitrogen, liquid oxygen, and liquid argon, the main body is resistant to low temperatures, prevents medium vaporization interference, and ensures stable liquid level measurement.
2. Contactless magnetic coupling measurement: The magnetic float rises and falls with the liquid level, and the external magnetic flap/sensor senses the signal. The measurement chamber has no electronic components and is suitable for low-temperature flammable and explosive media.
3. Multiple signal outputs are optional: It can be equipped with a magnetic flip board for on-site visualization, and can be equipped with a 4-20mA remote transmitter and switch alarm to achieve local display and remote control room monitoring.
4. Reliable sealing and low maintenance: The fully enclosed pressure bearing structure reduces the leakage of cold energy and is less prone to freezing, frosting, and blockage; There are no vulnerable mechanical transmission components inside, and there is basically no need for disassembly and maintenance in daily life.

Application industry:
1. Gas energy industry: air separation equipment, liquid gas storage tanks, liquid nitrogen, liquid oxygen, liquid argon low-temperature storage tank liquid level monitoring.
2. Chemical industry: low-temperature chemical storage tanks, low-temperature liquefaction medium reaction vessels, and buffer tank liquid level monitoring.
3. Biopharmaceutical industry: liquid nitrogen storage tanks for biological samples and liquid level measurement for low-temperature reagent storage containers.
4. Metallurgical welding industry: liquid gas supply station, liquid oxygen and liquid argon supply storage tanks, welding protection gas storage tank liquid level detection.

FAQ Performance Specifications

Q1: Will the liquid gas magnetic level gauge be affected by the vaporization bubbles of the medium for measurement?
Answer: The selection will be matched with an anti-vaporization structure to reduce the disturbance of boiling bubbles on the float inside the tank; Ensure the correct pressure interface during installation, which can generally be measured stably; Severe boiling conditions require prior notification to the manufacturer for special optimization.

Q2: Can it be directly used for liquid nitrogen working conditions at -196 ℃?
Answer: The liquid gas specific model is acceptable, but the ordinary magnetic flip plate is not. It is necessary to confirm the material and low-temperature resistance level of the sealing components, and specify the medium and minimum working temperature when ordering.
Q3: What are the common reasons for inaccurate remote signal transmission?

Answer: ① The float selection is incorrect, as the density of the low-temperature medium is low and the buoyancy of the float is insufficient; ② Poor insulation of the installation pipeline, external frosting and freezing causing the float to become stuck; ③ The installation of the remote sensor is offset and requires recalibration of the zero range.

Q4: What are the special requirements for installation?
Answer: It needs to be installed vertically, and the connecting pipeline between the tank and the liquid level gauge should be well insulated and kept cold; It is recommended to install a low-temperature shut-off valve for the valve; It is not allowed to strike the body randomly to avoid demagnetization of the magnetic steel.
