Greyline SFM 6.1 Ruggedized Slurry Flow Meter

Greyline SFM 6.1 Slurry Flow Meter

The Greyline SFM 6.1 was specifically developed for the slurry applications found in today’s industrial facilities. The SFM 6.1 incorporates more than 25 years of Pulsar Measurement ultrasonic flow measurement experience. 

With no need to shut down flow or interrupt processes, industrial and dredging operators can keep sites running to capacity and ensure that maximum flow rates are being reached. Configuration for this clamp on flow meter is easy with the user-friendly menu system and 26 million point data logger that allows operators to see flow charts and create dynamic reports on their process.

Operation

The SFM 6.1 Sensor transmits continuous high-frequency sound through the pipe wall into the flowing slurry. Sound is then reflected to the sensor from particles or gas bubbles within the liquid. If the liquid is flowing, the reflected sound returns at an altered frequency - this is called the Doppler effect. The unit continuously monitors this frequency shift to accurately measure flow inside the pipe.

Application

The SFM 6.1 works best in applications that would prove problematic for regular contacting flow meters. Since the sensor is mounted on the outside of a pipe, rather than directly contacting the material, it is unaffected by the wear and tear of abrasive slurries. A non-contacting sensor means there is no interruption to flow and no pressure drop.
