What kind of flow meter is suitable for measuring dirty or corrosive fluids?

A target meter is particularly well-suited for measuring dirty or corrosive fluids due to its design and operational principles. This type of flow meter utilizes a target that is placed in the flow path; as fluid flows past the target, it exerts a force proportional to the flow rate. The simplicity of this mechanism allows it to handle particulates and contaminants without the risk of clogging or damage to internal components, which is a common concern for other types of flow meters.

Additionally, target meters can be constructed from materials that resist corrosion, making them ideal for use with aggressive fluids. This adaptability ensures reliable measurements even in challenging environments where maintenance or extensive cleaning procedures might pose difficulties with other meter types, such as turbine meters, rotameters, or piezometers, which can be more susceptible to fouling or damage from corrosion.
