Jeskon Systems Private Limited

• Non-contacting flow monitoring specifically designed for limestone slurry, fly ash slurry, gypsum slurry and many others
• The Greyline SFM 6.1 was specifically developed for the slurry applications found in today’s coal fired power plants. Using a proprietary algorithm specifically designed for measuring slurry flow, the SFM 6.1 incorporates more than 25 years of Greyline ultrasonic flow measurement experience.
• 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.

• Each SFM 6.1 Slurry Flow Meter includes a strap-on ultrasonic sensor, an adjustable stainless steel mounting clamp and sensor coupling compound. The sensor fits on the outside of any pipe diameter ½" (12.7 mm) or larger. It takes just a few minutes to install. There is no need to shut down flow.

• 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
• Optimized for Slurries
• Easy, Intuitive Set-Up
• 5 Button Menu System
• Isolated 4-20mA Output
• Up to 6 Control Relays
• Optional Built In Data Logger

• This specification covers a non-intrusive, ultrasonic Doppler-type slurry flow meter as manufactured by Greyline Instruments Inc., Largo, Florida / Long Sault, Ontario. The instrument shall provide for velocity or volumetric indicating and transmitting of the flow rate in a full pipe.

• 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.

• The flow sensor shall be single-head, ultrasonic in a stainless steel housing. It shall be installed on the outside of a pipe without interrupting flow. The sensor shall be capable of continuous operation at temperatures from -40°F to 300°F (-40°C to 150°C), and to withstand accidental submersion pressures to 10 psi. Manufacturer's recommended coupling compound and stainless steel mounting clamp shall be included.
• Shall include 20 ft (6m) Sensor cable, shielded coaxial pair.
• Shall be capable of extending sensor cable up to 500 ft (152m) without requirement for operator adjustment.
• Shall be transformer isolated and designed to meet intrinsic safe requirements. Shall be designed for maximum RFI rejection, and include automatic high voltage bleeds for nearby lightning strikes.
• Sensor shall be rated Non-incendive for Class I, Division 2, Groups A, B, C & D locations.
