Liquid level detection is a crucial aspect of industrial process control. Depending on the specific conditions of the process, there are various methods for detecting liquid level. Among these methods, pressure-based detection understatic pressureis a simple, economical, and reliable option.
A static pressure level transmitter can be designed as an immersion type, which is commonly used for detecting liquid level in water tanks, dams, and other similar applications. When installing the sensor, it is important to calculate the length of the sensor and cable accurately. Ideally, the sensor should be placed vertically at the bottom of theliquid leveland not lie flat on the bottom.
For larger tank applications where the immersion cable is longer or the medium is corrosive, a side-mounted flange-type level transmitter is typically used for static pressure monitoring. This type of installation is simple, with a hole drilled in the bottom side of the tank and ahand valveinstalled at the front end, with the transmitter mounted behind the valve. This allows for real-time monitoring ofliquid level changes, and the sensing diaphragm can be made of different materials to meet a wider range of industry applications.
In thefirefighting industry, cost control is typically a major concern. Thus, pressure sensors without displays are commonly used. This option is simple, economical, and easy to install, with attention paid to the length of the immersion cable during installation, and the liquid level calculated based on the analog signal output.
It is important to note that different media will require different calculations forliquid level detection. Factors such as media density andvolume conversionmust be taken into account when determining the output signal proportion. Therefore, it is necessary to adjust the settings based on the actual medium being used.
