How to accurately measure tank level and volume: The rivalry between radar and magnetic level gauges, and the rise of double-flange gauges

Accurate measurement of the liquid level and volume in storage tanks is very important for industrial production. The commonly used level measurement techniques at present are radar and magnetic flap switches; in some cases, the double-flange installation method can also improve measurement accuracy. 1. Radar measurement technology: Radar level gauges use the properties of electromagnetic waves to measure liquid levels. It measures the liquid level by transmitting and receiving microwave signals, and converts these signals into liquid level values. This technology can be applied to various media, offering advantages such as high precision, contactless measurement, and immunity to the properties of the liquid. 2. Magnetic flap measurement technology: Magnetic flap level gauges measure the liquid level by altering the state of the magnetic flaps as the liquid level rises or falls. It features a simple structure, corrosion resistance, and low cost, making it suitable for measuring the level of certain ordinary media. 3. Double-flange installation method: For certain special media or situations where higher requirements are placed on level measurement, the double-flange installation method can be used. Dual flanges refer to the installation of level gauges on both sides of the storage tank, with the two measurement values being averaged to improve measurement accuracy. This installation method can reduce errors and impacts, thereby improving the reliability and accuracy of measurements. In practical applications, we need to comprehensively consider specific process requirements, medium properties, installation conditions, etc., in order to select the appropriate level measurement technology. At the same time, attention must also be paid to the appropriate installation location, proper calibration, and maintenance to ensure the accuracy of the measurement results. .

It’s a great thing! The significance isn’t very great; usually, this type of headed tank is used for measurement in the third installation method, and there is no need to calculate the volume of the head. No matter how accurate the measurements and calculations are, errors caused by irregularities cannot be avoided.

I really like those large clients for whom the liquid level is sufficient without the need to take the head into account. Occasionally, I encounter manufacturers for whom the head also needs to be taken into consideration. The materials are valuable, and there’s no way to waste them – it’s really a headache.
