Measurement probe and calibration probe of external-mounted level gauges

Could you explain the measuring probe and calibration probe of the external-mounted level gauge?

Under normal circumstances, due to changes in environmental conditions, in order to accurately measure the liquid level in storage tanks, a measuring probe is used to detect the level, and the probe is calibrated to account for those environmental conditions. You may refer to the one-on-one technical support for instrument issues of the [JST-104] external-mounted level gauge. If you’re still not clear, QQ: 2091552675.
You need to specify certain things: the calibration probe is used to set the sound speed inside the container, as well as parameters such as the transmission frequency factor of the probe. Once these parameters are set, they are copied to the measurement probe, which is responsible for measuring the liquid level inside the container. If the medium inside the container changes, it is necessary to reset it using the calibration probe and then copy it to the measurement probe! Generally, the measurement probe is installed at the very bottom of the container, with a coupling agent placed between it and the bottom of the container. The probe is usually mounted on the side of the container, and the exact installation location varies depending on the shape of the container
