In-Line Viscometer 311 Sanitary Sensor

Quick, Tool-Free Disconnect for Process Applications 

The Model SPC/L311 is an in-line or tank-vessel viscometer that is installed in process fluids to provide continuous temperature and viscosity tracking. The Cambridge Viscosity technology is based on a simple and reliable electromagnetic concept. Two coils move the piston back and forth magnetically at a constant force. Proprietary circuitry analyzes the piston’s two-way travel time to measure absolute viscosity. 

A deflector, positioned over the piston, moves fluid into the measurement chamber. This feature, coupled with the constant piston motion, keeps the sample fresh and mechanically scrubs the chamber. A built-in temperature detector (RTD) senses actual temperature in the measurement chamber. 

The Model SPC/L311 has a quick-connect disconnect Tri-Clover® flange. Typical systems include a tee, Tri-Clamp® and an application-specific gasket. 

Measurements can be made in 13 different 20:1 viscosity ranges within an overall span of 0.2 to 20,000 cP or the equivalent cSt. Maximum flow rate over the sensor head is 10ft/sec (3 m/sec).
