A hydrostatic level gauge, also known as a submersible level gauge, is a measuring device that is widely used in liquid storage tanks and pipelines. There are two main reasons for its name:
First, the working principle.
Hydrostatic level gauges work on the principle that the static pressure of the liquid column is balanced with the atmospheric pressure. When the static pressure generated by the liquid column is equal to the atmospheric pressure, the gas conduction system connected to the liquid column transmits the gas pressure to a pressure sensor, and by measuring this pressure, the depth of the liquid can be calculated. This principle of operation allows the hydrostatic level gauge to accurately measure liquids in a stationary or flowing state, hence the name "hydrostatic" level gauge.
Second, the installation method.
Hydrostatic level gauges are usually submersible mounted, i.e. the sensor is partially inserted into the liquid so that it is in contact with the liquid to measure the level. This simple and convenient installation method is suitable for level measurement in various liquid storage tanks and pipelines. Due to its submersible characteristics, hydrostatic level gauges are also known as submersible level gauges.
To sum up, the reason why hydrostatic level gauges are called submersible level gauges is mainly based on their working principle and installation method. The submersible installation allows the device to be easily used for level measurement in a wide range of liquid storage tanks and pipelines, while its hydrostatic principle ensures accurate measurement at rest or in a flowing state. Therefore, the name "hydrostatic level gauge" aptly describes its operating principle and measurement characteristics.
