WaterCompass FM300-US Ultrasonic Flow Monitor
Product Overview
The WaterCompass FM300-US is a customized product made up of an integrated WT2W-H20 Flow Decoder, a clamp-on flow monitor and a 30V power supply. These non-invasive flow monitors clamp onto existing pipe with mounting brackets that fit pipe sizes from ¼ inch up to 8”.
The integrated 2W-H20-FS Flow Decoder transfers the data from the flow monitor to the WaterCompass Data Collector where it is analyzed, reported, and acted on. Data is available for viewing on the WaterCompass dashboard.
· The monitor clamps onto the outside of a pipe and can accurately sense the flow of water through the pipe
· Requires no pipe modification
· Takes ultrasonic readings
