2024-07-26 15:44

          Double flanged liquid level transmitter is a kind of liquid level measuring instrument widely used in petroleum, chemical, pharmaceutical, electric power and other industries. Double flanged liquid level transmitter uses two flanges to isolate the measuring diaphragm directly from the medium, and realizes the liquid level measurement through the radar level transmitter, especially for high temperature, high pressure and strong corrosive liquid media. In this paper, the advantages and disadvantages of double flanged liquid level transmitters will be discussed, and the common faults and treatment methods will be analyzed.

First, the advantages of remote seal radar level transmitter

   1. Strong anti-interference ability

High temperature and high pressure adaptability: The double-flange liquid level transmitter can withstand high temperature and high pressure environment, and the medium is isolated from the sensor through the isolation diaphragm to ensure the stability and reliability of the measurement.The literature High-Temperature and High-Pressure Effects on Differential Pressure Transitters》(Journal of Pressure Vessel Technology, 2017pointed out that the double flange structure performs well at high temperature and pressure, and can effectively reduce the interference of the environment to the measurement.

Excellent corrosion resistance: In the selection of materials, corrosion resistant materials such as Hastelloy, titanium alloy, etc. are used so that materials, corrosion resistant materials such as Hastelloy, titanium alloy, etc can be used for a long time under harsh conditions such as strong acid and alkali.

2. High measurement accuracy

Differential pressure principle: The capillary radar level transmitter calculates the liquid level by measuring the pressure difference between two diaphragms, with high linearity and accuracy. According to the Accuracy and Reliability of Differential Pressure Transmitters in Level Measurement》(Sensors and Actuators A: Physical, 2018study, the measurement accuracy of the radar level transmitter is between ±0.1% and ±0.2%.

3. Easy maintenance

Easy calibration and maintenance: The structural design of the double-flange mounted pressure transmitter allows on-line calibration and maintenance without affecting normal production, reducing downtime and maintenance costs.

In the selection of industrial production needs, a suitable double-flange liquid level gauge can provide better measurement results.In the case of measuring the medium volume range is large, there are remote double-flange level transmitters(https://youtu.be/17nyHCIdyr4) can be selected.
