• Non-invasive flow metering with clamp-on sensors
• Quick, easy setup and operation
• Very accurate in a wide range of applications and pipe types

Transit time flowmeters are the most versatile, trouble-free and accurate flowmeters available. With easy-to-install, non-contact, clamp-on flow sensors and first-rate electronics, the Endress+Hauser Prosonic 91W is one of the best and most reliable transit time flowmeters on the market. Quick setup menus with built-in pipe and lining material combinations are just one of the Prosonic 91W's great features. Other outstanding features include stainless steel NEMA 4X sensors, robust NEMA 4X field housing, bi-directional rate/totalizer, 0.5% possible accuracy and a wide 2 to 80" pipe size capability.

Choose from three pipe ID size ranges. Each flowmeter comes with a single-channel NEMA 4X remote mount display/transmitter with push-button control, 4-20 mA output, HART® protocol, pulse/frequency output and two clamp-on sensors with 30 feet of cable. Other options are available, such as additional sensor cable lengths, smaller sensor assemblies for pipe as small as 1/2", insertion-type sensors and flanged inline sensors. Contact USABlueBook for more information.

Note: Each flowmeter includes a clamp-on sensor installation kit.
