Greyline - Model DFM 6.1 - Doppler Flow Meter
Measure flow from outside a pipe. The Greyline DFM 6.1 is designed for 'difficult liquids' that would damage regular flow meters - wastewater, slurries, sludge, chemicals, viscous liquids and abrasives. There is no obstruction to flow and no pressure drop. The non-intrusive, clamp-on ultrasonic sensor fits any pipe 1/2' (12.5 mm) Inside Diameter or larger. The DFM 6.1 features enhanced performance in a wide range of applications. Improved industrial noise immunity filters potential interference sources. Isolated 4-20mA output to transmit flow to remote displays, recorders or controllers. The programmable relays can be used for flow control, pump protection or flow proportionate pulse. Calibration is easy with the built-in 5-key calibrator. Display and totalize flow in your choice of engineering units (gallons, liters etc). A 128MB data logger is standard, capable of capturing up to 26 million data points. Optional MODBUS RTU via HART is available for connection to automation systems.
