The PF D550 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 PF D550 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.
 
Description
Use a PF D550 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 flow meter is not required or to temporarily replace installed flow transmitters.  Useful for liquids with high solids content like RAS, WAS, and sludge.  Great for aerated fluids as well.
