DFM 6.1 Doppler Flow Meter
Manufacturer: Pulsar MeasurementThe Greyline DFM 6.1 is designed to measure flow from outside a pipe 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 12.5 mm (0.5 in) Inside Diameter or larger.
The Greyline DFM 6.1 features enhanced performance in a wide range of applications.
Improved industrial noise immunity filters potential interference sources.
Use the isolated 4-20 mA 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.
A 128 MB data logger is standard, capable of capturing up to 26 million data points.
