OMEGA FDT40 Clamp-On Ultrasonic Flowmeter

FLOW METER FDT-40 Series ultrasonic flow and energy meters clamp on to the outside of pipes and do not come in contact with the internal liquid. The technology has inherent advantages over alternate devices including: low-cost installation, no pressure head loss, no moving parts to maintain or replace, no fluid compatibility issue, and a large, bi-directional measuring range that ensures reliable readings even at very low and high flow rates. FDT-40 Series is available in a variety of configurations that permit the user to select a meter with features suitable to meet particular application requirements.
