Non-invasive flowmeter a fit for large-diameter pipes

Monitoring flows in large-diameter pipes is notoriously expensive. However, it is now possible to measure flows in large water mains using clamp-on flowmeter technology. The TFX-5000 transit time ultrasonic flowmeter from Badger Meter has a wide, bidirectional flow measuring range and no pressure head loss. It also meets requirements for lead content in potable water plumbing products by never coming into contact with the water.

“The TFX-5000 meter is a clamp-on, non-invasive meter,” says Cheryl Ades Anspach, senior product manager at Badger Meter. “It can be installed quickly and easily without cutting or tapping process piping and can be retrofit in existing installations without shutting down systems operations — reducing both installation time and material costs.”

The TFX-5000 measures volumetric flow and heating/cooling energy rates in clean liquids as well as those with small amounts of suspended solids or aeration, such as surface water. By clamping onto the outside of pipes, the meters have inherent advantages over other flowmeter technologies, including reduced installation time and cost; non-invasive, non-contact measurement; continued operation during installation, as there’s no need to shut down the process; no pressure head loss; and no moving parts to maintain or replace.

“Customers prefer the TFX-5000 because it offers easier wiring and checkout, and its cover can be hinged open or completely removed to allow easier access to wiring in tight spaces,” says Ades Anspach. “It features resistors integrated on the main board, which eliminates sourcing and the installation of external resistors, such as RS-485 terminating resistors. Test modes for current and digital outputs also ensure the signals get through to building automation systems.”

The TFX-500 can data log up to eight records using Modbus RTU or BACnet MS/TP over EIA-485; Modbus TCP/IP; BACnet/IP; EtherNet/IP; or AquaCUE/BEACON connectivity. Users can configure and troubleshoot over USB with SoloCUE. It includes ultrasonic speed and temperature compensation; a large, easy-to-read graphical display; and a rugged aluminum enclosure for a long service life in harsh environments. It is available in a variety of configurations that permit the user to select a meter with features suitable to meet particular application requirements.

“Installation and setup can be completed by a single person within an hour, which is a benefit in both new and retrofit system and supports social distancing guidelines,” says Ades Anspach.
