Compared to other level gauge products, external level gauges have the advantage of not requiring any drilling, welding, or tank cleaning; they are safe and do not disrupt production, which provides great convenience for many chemical companies, especially when it comes to upgrading the methods used for measuring liquid levels in storage tanks. So, how should we choose level gauges from different manufacturers? As for the external level gauge products themselves, it is essential that we understand whether their various specifications meet the requirements of actual measurement conditions. External level gauges designed by different manufacturers differ in terms of measurement range, accuracy, and explosion-proof capabilities; therefore, it is necessary for us to have a clear understanding of the characteristics of these products from various manufacturers. Field application examples of external level gauges: It is necessary to find the right product and also determine its application cases. The specifications of an external level gauge can indicate its measuring capabilities, but assessing its stability and reliability requires looking at actual application cases; this is another important factor in verifying whether a manufacturer’s products are of satisfactory quality. Qualifications for external level gauges: At present, in accordance with the requirements of the Work Safety Supervision Bureau, many petrochemical manufacturers need to ensure that the products they purchase possess relevant qualifications, such as explosion-proof certificates, safety grade certifications, and so on. The quality of manufacturers of external level gauges: Good products necessarily rely on strong financial capabilities, and this is true as well when choosing manufacturers of such devices. If one has the time and effort, it’s best to visit the manufacturers’ facilities in person; this way, one can ensure that they are getting high-quality products from reliable manufacturers.
