Product Specs

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.

Cables: RG59 coaxial, 75 ? or twin axial, 78 ? (optional armored conduit)
Cable Length: Standard 6 m (20') 300 m (990') maximum in 3 m (10') increments Software Utilities Utilized to configure, calibrate and troubleshoot flowmeters. Connection via USB A/B cable; software is compatible with Windows 2000, Windows XP, Windows Vista® and Windows® 7
RS485 Network All FDT-40 meters come equipped with RS485 drivers and utilize a MODBUS RTU command set (data can be returned in single-precision, doubleprecision, integer or floating point values). Up to 126 units products can be run on a single daisy-chain network and be individually queried for flow rate, positive flow accumulator, negative flow accumulator and signal strength. Flow accumulators can be cleared at discrete addresses or globally. The RS485 network is also compatible with direct to Excel, application.

Rated 1 out of 5 by from Insufficient manual Especially USB programming port, the manual is not enough. TypeB and USB connection is OK in my case, my there is no software called USP and its setup file "USP_Setup.exe" and also its location. It took a lot of time to figure out and it is impossible to handle it. I won't recommend ever!

Will this product read flow of a carbonated product?

Asked by: Waylon
Thank you for your inquiry about this flow meter. The bubbles may be a problem since the Transit Time ultrasonic flow meter is best for measuring clean liquids with no suspended particles. Carbonation may require the use of the Doppler style ultrasonic flow meter.

Need a strap-on flowmeter that can handle 500 degree oil, pipesizes from 6" to 4"

Asked by: Bill69
Thank you for your inquiry about an ultrasonic flow meter. Unfortunately, Omega does not have an ultrasonic flow meter rated for extreme high temperatures. Best to search via Thomasnet.com to determine if this flow meter is available.

For a 1/2" copper pipe how small a flow rate can this detect?

Asked by: bob27
Thank you for your inquiry. The minimum flow rate that the ultrasonic flow meter will measure is 1.8 GPM, nothing lower.
