Reliable level measurement starts with a hydrostatic level transmitter you can trust. At Pondus Instruments, we design and manufacture rugged, accurate transmitters for continuous level monitoring in tanks, wells, boreholes, reservoirs and industrial process vessels—clean or harsh, fixed or mobile installations.
What is a hydrostatic level transmitter?
A hydrostatic (pressure-based) level transmitter measures the liquid column’s pressure and converts it into level. Because it is based on fundamental physics, this method is stable, drift-resistant and unaffected by foam, vapour or surface turbulence. Whether you call it a hydrostatic level transducer, hydrostatic pressure level transmitter, or simply a hydrostatic transmitter, the result is the same: dependable, continuous level data you can act on.
Looking for LTU801 or LTU601?
If you’re searching for legacy part numbers:
- LTU801 → Choose LT100 or LTU701
These Pondus models are modern, high-performance solutions that match the typical LTU801 use cases with improved usability and lifecycle support.
