Description

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 souces.

Use the 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.

Sensor cable can be extended up to 500 ft. (152 m) with no loss of signal. The standard sensor is rated non-incendive for Class I, Division 2 hazardous locations and the DFM 6.1 can be equipped with optional Intrinsic Safety Barriers for sensor installation in Class I, Division I hazardous locations.
