How it is selected & specified.
The water and fuel tank ultrasonic level meter page is a dedicated application product for common storage duties. It covers water tanks, reservoirs, utility tanks, diesel day tanks and selected fuel storage applications where a non-contact sensor is preferred.
For water, the main checks are tank height, blind zone, outdoor exposure, stilling conditions, foam and bracket position. For diesel or fuel, WELK also checks vapor, hazardous-area requirement, tank venting, temperature and whether radar or an external gauge is safer.
This product can use an integrated ultrasonic meter, split ultrasonic meter or two-wire transmitter depending on display and control needs. It is listed separately because buyers often search by tank duty rather than by instrument structure.
For drinking water, material compatibility and sealing details should be reviewed. For fuel, never select only from range and price; site safety classification and document requirement must be confirmed first.
