Portable Doppler Flow Meter

PULSAR PDFM 6.1

Portable Doppler Flow Meter for quick and easy flow measurement using a non-invasive ultrasonic sensor, designed for liquids containing suspended solids or bubbles, with a minimum size of 100 microns and a concentration of at least 75 ppm.
Ideal for flow monitoring and balancing, troubleshooting flow issues, verifying measurements of flow meters, and addressing problems in full pipes.
Use it for projects with continuous flow where a flow meter is not required, or as a temporary replacement for an installed flow meter. It is ideal for applications involving wastewater, slurries, sludge, viscous liquids, slurry materials, and abrasives.
