SFM 6.1 Ultrasonic Slurry Flow Meter
- Type Of Detector
- Chlorine Analyzer
- Manufacturer
- SFM 6.1 Slurry
The SFM 6.1 Slurry Flow Meter works best in applications that would defeat regular contacting flow meters. Because the Sensor is mounted on the outside of the pipe, it is unaffected by abrasive slurries or harsh chemicals. There is no obstruction to flow and no pressure drop.

Features
Digital processing system tracks flow signals accurately and auto-zeroes with signal loss
Noise suppression circuitry filters “dirty” power and electrical interference from most VFD's
Automatically converts between measurement units (e.g. gallons or liters)
Calibration data and Totalizer values are stored automatically during power interruptions
Output “simulation” function simplifies calibration of remote devices (e.g. chart recorders or controllers)
Self-tunes to Sensor cable length
Product Literature
The flow meter shall operate with a single-head flow sensor mounted externally on any contiguous pipe material that conducts sound including: carbon steel, stainless steel, ductile iron, copper, FRP, PVC, ABS, or cement lined pipe from 1/2" to 180" (12.5 mm to 4.5 m) ID.
Measure and indicate flow rates from +0.25 to +40 ft/sec and -0.25 to -40 ft/sec (+0.075 to +12.2 m/sec and -0.075 to -12.2 m/sec) with accuracy of ±2% of reading on liquids with entrained particles or gases of 100 microns or larger and minimum concentrations of 75 ppm.
How it works
The Doppler technique only works on liquids which contain solids or gas bubbles to reflect its signal. These are "difficult" liquids that may damage regular flow meters: slurries, sludge, wastewater, abrasives, viscous and corrosive chemicals. Because the sensor mounts on the outside of the pipe, there is no pressure drop and no obstruction to flow.
For best performance Doppler sensors should be mounted away from turbulence creating devices like pipe elbows and tees, and away from velocity increasing devices like controlling valves and pumps. Typical accuracy is ±2% of full scale. Doppler instruments include a clamp-on ultrasonic sensor, connecting cable and an electronics enclosure which can be mounted at a convenient location nearby (within 500 ft / 152 m).
