1. Storage tank capacity: For large tanks (10000-100000m) and relatively large liquefied gas tanks, high-performance level gauges can be used, while general level gauges can be used for small and medium-sized tanks;
Purpose of storage tank: High precision level gauges should be used for trade tanks, and general level gauges can be used for intermediate tanks.
2. Liquid level characteristics: When storing liquids with high viscosity (such as heavy oil), it is recommended to use level gauges that do not or have minimal contact with the measured liquid level, such as radar, ultrasonic, and magnetostrictive level gauges. For light oil, general level gauges can be used;
3. User's actual needs: If the user requires high measurement accuracy with few investment restrictions, a high-performance liquid level gauge can be used. Generally, when renovating or updating an old tank area, the selection can be considered based on the use and maintenance of the original liquid level gauge, and the selection should be as uniform as possible.
advantage
Radar level gauge is a non-contact measurement or TDR guided wave measurement
Radar level gauges use electromagnetic pulses for rapid measurement, with high accuracy and strong resistance to force
Corrosion resistance (probes are mostly made of materials such as 316 stainless steel or PVDP)
High pressure resistance (40Kg/cm2)
High temperature resistance (200 ℃)
