Liquid level measurement is widely used in the production device of offshore oil fields,which is one of the important means to ensure production. The float type magnetostrictive liquid level transmitter of the American K-TEK company is widely used in the liquid level measurement of the offshore platform. As it is a contact liquid level meter,the buoy is immersed in the measured medium. The platform has high viscosity of crude oil and oil and water both contain polymer flooding. The field condition is rather complicated. In practice, the phenomenon of float blocking frequently appears in this liquid level meter,which affects the stability of production process and increases the workload of maintenance personnel.Aiming at the liquid level measurement of viscous medium on site,this paper analyzes various kinds of liquid level transmitters,discusses its usability,and reselects the liquid level gauge.
