The dual tube model SLMx-2 is an accurate, efficient and reliable flow meter that is specially designed for applications where uninterrupted seal water flow is required. Proper adjustment of flow and pressure will result in significant water and energy savings. Our strong and compact design ensures maximum resistance to external impact.

The SLM has been optimized to withstand contaminated water and it comes with a built-in flow tube cleaner. Its reliable and accurate flow measurement is based on a variable area metering principle using a free-floating float.

The SLM comes in many different models, which guarantees compatibility with all seal types. The SLM can also be easily equipped with an alarm output by installing an inductive proximity sensor. Typical applications are double mechanical seals.
