SAFSONIC FIXED DOPPLER FLOWMETERDFM2? Single non-invasive clamp-on sensor? Pipe sizes DN25 to DN3000? Extended cable with inline transmitter? Flow total and rate display? Microprocessor Programmable? Analogue, Pulse & Relay outputs? Metric and US units? Quick to install & Easy to use? Low costExample Applications? Process control? Pump protection? Backup flow meter in emergenciesExample Liquids? Mining & Dredging Slurries? Paper & Food Pulps? Water & Sewerage SludgesThe Safsonic DFM2 is a non-invasive ultrasonic flow meter for the measurement and control ofliquids flowing through process and effluent pipelines using the non-intrusive Doppler principle. Theflowmeter display indicates flow rate and total volume for a range of liquids containing suspendedsolids, including aerated water, slurries and sludges. The Safsonic DFM2 requires fluids with aminimum concentration of 100ppm of solids or bubbles having minimum size of 100microns.Features & SpecificationsVelocity Range 0.25 to 10m/s (0.82 to 30.5ft/s)Liquids Containing 0.01% solids >100micronPipes 25-3000mm (1”-120”) Most pipe materialsAccuracy ±2% of Rate for velocities >0.5m/s (1.6ft/s)Repeatability ?2%Indication Rate and Total (password resettable)2 - Line 16 Character backlit LCDUnits Rate units: m/s, l/s, l/m, l/hr, m3/s, m3/m,m3/hr, ft/s, ft3/s, ft3/m, ft3/hr, USgps, USgpm,USgph, USmgd Total units: l, m3, Ml, ft3,103ft3, 106ft3, USG, 103USG, 106USGPower Supply 115/230Vac ±10%, 50/60Hz, (<6VA)24VDC, ±10%, (<4W)Programming 4 Key external keypadIsolated Outputs Active 4-20mA (<700O load)24VDC Auxiliary supply (<50mA)OCT Totaliser pulse (=24VDC =500mA)Relay Form C (1A 125VAC 2A 30VDC)Flow Rate Alarm, Signal Loss, TotaliserRS485 Modbus RTU (Optional)Response Time 3 Selectable levels of dampingElectronicsenclosureIP67 (NEMA 6) Polycarbonate Wall Mount125 x 125 x 75mm HxWxD (5” x 5” x 3”)Transducer IP68 (NEMA 6P) Aluminium epoxy-faced21 x 80 x 28mm HxWxD (0.8” x 3” x 1.1”)TemperaturelimitsSensor -20 to 90ºC (-4 to 194ºF)Electronics -10 to 50ºC (14 to 122ºF)Inline transmitterenclosureIP67 (NEMA 6) Aluminium Epoxy coated75 x 80 x 57mm HxWxD (3” x 3.1” x 2.2”)Cable length withinline transmitter3m (9ft) Sensor to transmitter and =100m(300ft) from transmitter to DFM2 displayShipping 36x20x13cm (15” x10” x5.2”), 2kg (5lbs)Model No. DFM2-2-1-x (115VAC 50/60Hz)DFM2-2-2-x (230VAC 50/60Hz)DFM2-2-3-x (24VDC)Model Example DFM2-2-1-30115VAC 50/60Hz with 30m sensor cableStandards CE CertifiedCalibration Certificate with each flow meter05www.flowmetrix.co.za enquiries@flowmetrix.co.za
