What LibertyCES's vendor documentation shows

Signet names Plating Lines and Neutralization Tanks explicitly among the 2250's applications, alongside inventory management, storage tank monitoring, waste sumps, clarifiers and overflow protection. The design justification is transferable: the flush ceramic diaphragm disregards false level signals from steam vapors, foam and surface debris, which is why hydrostatic beats acoustic in a fuming plating tank — Signet's own Level Application Suitability Matrix rates hydrostatic '+' for dense surface foam while rating 2260/2270 ultrasonic '-'. Two install requirements not to miss: the sensor's back-end capillary tube must be exposed to atmospheric pressure, and Signet says use the 2250 rather than the 2450 for anything mounted inside a tank.
