Description

Monitoring in Realtime at the Volume Measuring Device For Storage Tank Load}

The present invention relates to a storage tank load volume measurement device that is monitored in real time, and more specifically, improves a structure for measuring the loading amount of powder and fluid loads inside the storage tank to improve the accuracy of measurement and the degree of the load from a remote location. It relates to a storage tank load volume measurement device that is monitored in real time, which can be checked and can facilitate the maintenance of materials.

In general, a storage tank in which raw materials such as fluids and powders are stored requires confirmation of the loading amount of the stored raw materials for the purpose of maintaining a storage amount suitable for capacity and confirming the amount used.

In this way, the device for measuring the loading amount of the storage tank should continuously measure the loading amount of the material in which the raw materials of the powder and fluid are stored, depending on the use, but in the case of powder, the surface is uneven and dust is generated by contact. In this case, it is difficult to measure because it is shaken by external shock or small vibration, and the surface is deformed when contacted.

Thus, the storage tank load volume measurement device of the prior art is a device that measures the level, which is the height of the load, in a non-contact method using ultrasonic waves.

However, in the conventional apparatus for measuring the volume of a load using ultrasonic waves, when the ultrasonic waves are irradiated on the surface of an irregularly loaded powder, a signal that is rapidly scattered and reflected is weak, so that accurate measurement is difficult.

Accordingly, recently, a device has been developed and used to improve measurement efficiency by reflected waves while minimizing scattering by measuring the level and level of a load while rotating by a rotating means using a single light.

However, since a device using a single light includes a rotating means, the wiring is connected to supply power from the outside as a lot of power is used. In case of rain, a short circuit occurs or it acts as a conductor for lightning, causing damage. There was a problem.

In addition, as a single light measures the level of the surface by rotation, it takes a long time to measure the level, and if the surface is irregular, it is impossible to measure with a single rotation, and thus there is a problem in that the accuracy is poor.
