Ideal for Problem Liquids
Use a Greyline PDFM 5.0 Portable Doppler Flow Meter to monitor and
balance flow, or to troubleshoot flow problems in full pipes. It is ideal to
evaluate performance of in-line flow meters and can be installed,
calibrated and started-up in minutes. Use it for projects where a
permanent flowmeter is not required or to temporarily replace installed
flow transmitters.
The PDFM 5.0 ultrasonic sensor is clamped on the outside of a pipe. An
acoustic pulse is reflected back to the sensor from particles or gases in
the flowing liquid. The flow rate of any fluid can be measured 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 PDFM 5.0 can be operated all day and then
recharged overnight. For continuous use it can be powered by a supplied
110-240VAC wall plug adapter. A 300,000 point data logger is built-in.
