Measure flow from outside a pipe. The
Greyline DFM-IV is ideal 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 standard,
strap-on ultrasonic sensor fits any pipe 1/2" (12.5 mm) Inside Diameter or
larger. The electronics/display enclosure can be mounted nearby.
Use the isolated 4-20mA to transmit
flow to remote displays, recorders or controllers. The 3 programmable relays
can be used for flow control, pump protection or flow proportionate pulse.
Calibration is easy with the built-in 3-key calibrator. Display and totalize
flow in your choice of engineering units (gallons, liters etc.)
Sensor cable can be extended up to 500
ft. (152 m) with no loss of signal. The DFM-IV can be equipped with intrinsic
safety barriers for sensor installation in hazardous rated locations. Other
options include high temperature sensors, dual-head sensors and a built-in 50,000 point Data
