Design of liquid level gauges for steel storage tanks
Thread Content
Since the stored material tends to compact and settle at the bottom, there is a 30-cm blind zone around the magnetic flap level gauge where it cannot detect anything within 30 cm of the tank bottom. Is this acceptable?
In the design of level gauges for steel storage tanks, if the material stored tends to agglomerate and settle at the bottom, the use of magnetic flap level gauges may indeed be affected. The magnetic flap level gauge has a 30 cm blind zone, which means that the liquid level 30 cm below the bottom of the tank cannot be detected. If this level of liquid is crucial for the operation and safety of the entire storage system, then this blind spot can pose a problem. The following solutions can be considered: 1. **Choose another type of level gauge**: such as an ultrasonic level gauge or a radar level gauge. These types of level gauges have fewer or no blind spots, making them more suitable for applications that require accurate detection of the liquid level at the bottom. 2. **Adjust the installation position of the magnetic flap level gauge**: Try to install the level gauge at a lower position to minimize the impact of blind zones on detection. 3. **Use a combination of various detection techniques**: In those blind areas that cannot be covered by magnetic float level gauges, consider installing point-type level switches and similar devices to achieve more comprehensive level monitoring. The most suitable level detection solution must be selected by taking into comprehensive consideration the specific tank design, properties of the material, and safety requirements. .
If a liquid level below 300 MM is a very important parameter for your company that needs to be monitored, it is recommended to use a level switch.
