A Tek-Hydro 4500A-D series differential pressure level transmitter is a commonly used instrument which measures the level of a liquid in a tank. It is a simple device used in a wide range of liquids, including corrosive, non-corrosive and abrasive liquids and slurries in tanks of any size.

It can handle broad temperature and pressure ranges under different process conditions. Tek-Hydro 4500A-D series has flexible sensor input which measures hydrostatic pressure head and converts into a liquid level. It is used to measures not only the liquid level but also other parameters such as the flow rate and density. This transmitter has a maximum pressure up to 1000PSI.
