DFM-5.0 Fixed Doppler Flow Meter 13mm to 4500mm
Suitable for various contaminated fluid flows

 

Use a PDFM5.0 Portable Doppler Flow Meter to monitor and balance flow,or to trouble shoot flow

problems in full pipes.It is ideal to evaluate performance of in-line flowmeters and can be installed,

calibrated and started-up in minutes. Use it for projects where a permanent flow meter is not required

or to temporarily replace installed flow transmitters. The PDFM4.0 ultrasonic sensor is strapped on the
outside of a pipe. An acoustic pulse is reflected back to the sens or from particles or gases in the flowing liquid.

The flow rate of any fluid can bemeasured as long as it contains air bubbles or solids.It is ideal for wastewater,
slurries, sludge, and most chemicals,acids,caustics,and lubrication fluids.With its internal battery the PDFM4.0

can be operated all day and then recharged overnight.For continuous use it can be powered by115/230VAC

or 12VDC power inputs.
