Accurate means of measuring liquid level using LVDTs

Although there are various options for measuring liquid level in a tank, RDP Electronics Ltd are able to provide an LVDT based solution that can often be used where other methods are inappropriate.

Typically the LVDT is fitted with a weighted float and installed with the transducer directed vertically downward towards the liquid surface. This approach is often suitable where the liquid inside may form a foam on top, precluding the use of optical devices. LVDTs can also be used in some Intrinsically Safe (IS) applications where the liquid may be flammable or surrounded by explosive gas, which could exclude many other types of devices. Where there is a risk of liquid rising too high in the tank, then the use of submersible version LVDTs will ensure the device is adequately protected, while the fully stainless steel body of the transducer reduces concern for deterioration in corrosive or saline fluids. The RDP range also includes seawater submersible versions of the SS Series.
