Ultrasonic Doppler Flow Meter for Accurate Flow Measurement DFM 5.1
- Monitors, Displays, Totalizes and Controls from Outside a Pipe
- Ideal for full pipes and any liquid containing gas bubbles or solids larger than 100 microns and in concentrations greater than 75 ppm.
- The DFM 5.1 flow sensor installs without cutting the pipe. It takes just a few minutes to mount on the outside of any pipe.
- Calibration is easy with the built-in, 5-button keypad.
Special Features
- Digital processing system tracks flow signals accurately and auto-zeroes with signal loss
- Noise suppression circuitry filters âdirtyâ 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 âsimulationâ function simplifies calibration of remote devices (e.g. chart recorders or controllers)
- Self-tunes to Sensor cable length
- Benefits of Non-Contacting Flow Measurement
- No Contact means no maintenance, no sensor fouling, no obstruction to flow, no pressure drop, no corrosion and no pipe cutting or drilling for installation.
Designed for:
- Raw Sewage
- Treated wastewater
- Viscous liquids
- Chemicals and Acids
- Sludge and Slurries
- Solvents
- Pulp stock
- Food products
- Lubricating Oils
- Crude Oil
- Cooling Water
