"Rosemount vibrating fork switches are used to detect liquid level for high and low level alarms, overfill prevention, pump control, and hygienic applications. They are immune to changing process conditions and provide easy installation with no calibration required.​​​​​​​​​​​​​​​​"

"Vibrating Fork Level switches utilize a piezoelectric-driven tuning fork that exhibits a large change in resonant frequency when immersed into a liquid or bulk solid process." ( )

"Fail safe self monitoring level switch
If you want to detect liquid level directly with a switch, or you have an existing float switch, you could consider an upgrade to a more secure ‘fail safe’ device. A tuning fork level switch uses a vibrating element to detect liquid level by monitoring the change in vibration frequency when immersed in a liquid. It can be mounted in any orientation and supplied at various lengths in a range of materials. A tuning fork vibrating level switch will work on a range of changing densities, pressures and temperatures, with the new, latest generation vibrating switches capable of liquid specific gravities."

neutral  Barend van Zadelhoff: A tuning fork (stemvork) is used by otolaryngologists and orthopaedic surgeons for example rather than in chemistry // I would avoid it as an option given the strong ambiguity.

  -> Barend, the main 2 terms used are vibrating fork, and vibronic fork. However, if you look at reliable English-language refs, you'll see that they're sometimes also referred to as "tuning forks", obviously because they resemble the musical ones.

Reference: FWIW: level sensors

Reference information:
Level sensors detect the level of liquids and other fluids and fluidized solids, including slurries, granular materials, and powders that exhibit an upper free surface. Substances that flow become essentially horizontal in their containers (or other physical boundaries) because of gravity whereas most bulk solids pile at an angle of repose to a peak. The substance to be measured can be inside a container or can be in its natural form (e.g., a river or a lake). The level measurement can be either continuous or point values. Continuous level sensors measure level within a specified range and determine the exact amount of substance in a certain place, while point-level sensors only indicate whether the substance is above or below the sensing point. Generally the latter detect levels that are excessively high or low.

Vibrating point

These detect levels of very fine powders (bulk density: 0.02 g/cm3 – 0.2 g/cm3), fine powders (bulk density: 0.2 – 0.5 g/cm3), and granular solids (bulk density: 0.5 g/cm3 or greater). With proper selection of vibration frequency and suitable sensitivity adjustments, they can also sense the level of highly fluidized powders and electrostatic materials.

Single-probe vibrating level sensors are ideal for bulk powder level. Since only one sensing element contacts the powder, bridging between two probe elements is eliminated and media build-up is minimized. The vibration of the probe tends to eliminate build-up of material on the probe element. Vibrating level sensors are not affected by dust, static-charge build-up from dielectric powders, or changes in conductivity, temperature, pressure, humidity or moisture content. Tuning-fork style vibration sensors are another alternative. They tend to be less costly, but are prone to material buildup between the tines,

agree  Michael Beijer: Thanks for proving I was right (about use of the phrase "tuning fork" in this context) ;-) / neither would I. I just gave it as a synonym, as I found it used on reputable sites. my main answer is "vibrating fork", which you apparently don't agree with
1 hr
  -> --> 'tuning-fork style/like/shaped vibration sensors' takes the strong ambiguity out of it. I would not use 'tuning fork/stemvork'.
