Dynasonics TFX-5000 Fixed Clamp-On Ultrasonic Flow Meter

Overview

The Dynasonics TFX-5000 is a fixed, permanently installed clamp-on ultrasonic flow meter engineered by Dynasonics, a Badger Meter brand, for continuous, non-invasive liquid flow measurement across pipe sizes from 15 mm to 1200 mm (½ to 48 inches). Built around transit-time ultrasonic technology, the TFX-5000 clamps directly onto the outside of an existing pipe, eliminating the need to cut into the process line, drain the system, or install in-line wetted components. This makes it a preferred choice for facility engineers and plant operators who need dependable flow data on water, chilled water, condenser water, and other clean-to-moderately-clean liquids without the installation cost, downtime, and leak risk that come with traditional insertion or in-line metering technologies.

As the official authorized partner and exclusive regional representative for Dynasonics, Seven Star LLC proudly supplies the TFX-5000 clamp-on ultrasonic flow meter to industrial facilities, utilities, and building services contractors across Oman and the wider GCC. Every unit shipped through Seven Star LLC carries full manufacturer warranty coverage, genuine BACnet, Modbus, and EtherNet/IP-ready firmware, and access to regional technical support, so engineering teams from Muscat to Sohar can specify the TFX-5000 with confidence that the instrument, its documentation, and its long-term support are all backed by an authorized supply channel rather than a grey-market import.

Measurement Principle

The Dynasonics TFX-5000 measures flow using the transit-time ultrasonic method, in which a pair of transducers mounted on the outside of the pipe send ultrasonic pulses diagonally across the flowing liquid, one pulse traveling with the direction of flow and the other against it. Because the pulse moving downstream reaches the opposite transducer faster than the pulse moving upstream, the meter calculates this tiny time difference and converts it directly into a highly accurate flow velocity, which is then combined with the known internal pipe diameter to produce a volumetric flow rate. This is the same transit-time principle the Dynasonics TFX-5000 relies on, and it works reliably on a wide range of pipe materials, including steel, copper, PVC, and ductile iron, provided the liquid is reasonably free of large gas bubbles or heavy solids that would scatter or block the ultrasonic signal path.

Because the TFX-5000 never contacts the liquid directly, it introduces zero pressure drop into the piping system, has no seals or bearings that can wear or leak, and requires no process shutdown for installation, calibration checks, or maintenance. There are no moving parts to foul with scale, sediment, or corrosion products, which means the meter’s accuracy is not subject to the gradual mechanical degradation that affects paddlewheel, turbine, or positive-displacement meters over years of continuous service. For facilities running district cooling loops or continuous process water systems around the clock, this translates directly into lower total cost of ownership and fewer unplanned maintenance interventions.

Engineering Design of the Dynasonics TFX-5000

The Dynasonics TFX-5000 is built around a rugged, NEMA/IP-rated transmitter enclosure suitable for both indoor panel mounting and outdoor field installation, with a backlit alphanumeric display that shows instantaneous flow rate, totalized volume, and diagnostic signal-strength data directly at the point of measurement. The clamp-on transducer pairs are supplied in size-matched mounting fixtures that hold precise transducer spacing and alignment on the pipe surface, using an acoustic couplant gel to ensure consistent signal transmission through the pipe wall. For the Dynasonics TFX-5000, installation is a bolt-on, tool-light process: technicians select the correct transducer spacing from the supplied mounting rail based on pipe outer diameter and wall thickness, secure the transducers with the integral banding straps, and connect the transducer cable back to the wall- or pole-mounted transmitter.

On the electronics side, the TFX-5000 is powered from a universal supply accepting 9 to 28V DC, 20 to 26V AC, or 85 to 265V AC, giving specifying engineers flexibility to match whatever power infrastructure already exists at the metering point. Communication is where the TFX-5000 distinguishes itself from simpler clamp-on meters: it natively supports BACnet MS/TP, BACnet/IP, Modbus RTU, Modbus TCP, and EtherNet/IP, all BACnet Testing Laboratories (BTL) certified, along with Badger Meter’s BEACON/AquaCUE connectivity for remote data collection. This makes the TFX-5000 a natural fit for building automation systems (BAS) and building energy management systems (BEMS) that need direct flow and energy data without a protocol gateway in between.

Key Features

The Dynasonics TFX-5000 clamp-on ultrasonic flow meter combines broad pipe-size coverage with multi-protocol connectivity in a single fixed installation, and the Dynasonics TFX-5000 key capabilities include the following.

• It measures flow non-invasively on pipes from 15 mm to 1200 mm in diameter without cutting the pipe or interrupting the process.
• It achieves an accuracy of ±0.5% of reading ±0.025 ft/s (0.008 m/s), with repeatability of ±0.2%, across a wide flow velocity range.
• It operates across a liquid temperature range of –40°C to 176°C (–40°F to 350°F), suiting both chilled water and elevated-temperature process lines.
• It natively supports BACnet MS/TP, BACnet/IP, Modbus RTU, Modbus TCP, and EtherNet/IP for direct integration into building automation and SCADA systems.
• It accepts universal power input from 9–28V DC, 20–26V AC, or 85–265V AC, simplifying specification across mixed electrical infrastructure.
• It has no wetted parts and no moving components, eliminating pressure drop, leak points, and mechanical wear over the meter’s service life.
• It carries CSA certification for ordinary and hazardous locations and MCERTS certification for DN65–DN300 pipe sizes, supporting regulated water and utility applications.
• It provides BTL-certified energy and flow measurement per ISO 16484-6, making it suitable for BTU/energy metering in district cooling and HVAC energy audits.

Industrial Applications

The Dynasonics TFX-5000 is widely specified across Oman and the GCC on district cooling networks, commercial and hospitality HVAC systems, and industrial process water lines where a permanent, accurate flow reading is needed but cutting into the pipe is impractical or undesirable. In Muscat’s growing stock of mixed-use towers and hotel complexes, the TFX-5000 is used to sub-meter chilled water consumption per building or per floor, feeding directly into BACnet-based energy management platforms so facility teams can track cooling load and bill tenants accurately. In the Sohar and Salalah free zones, industrial plants use the Dynasonics TFX-5000 on cooling water loops, effluent lines, and utility water headers where continuous, maintenance-light flow monitoring supports both process control and regulatory reporting without the downtime a wetted meter installation would require.

As the officially authorized partner for Dynasonics, Seven Star LLC distributes the TFX-5000 to water authorities, district cooling operators, and industrial engineering contractors throughout the Sultanate of Oman and the broader GCC, backed by regional stock availability and manufacturer-trained technical support. Facility managers in Muscat, Sohar, and Salalah rely on Seven Star LLC not only for the instrument itself but for sizing guidance on transducer spacing, protocol integration support for BACnet and Modbus networks, and access to genuine Badger Meter documentation and firmware updates, all of which are only reliably available through an authorized regional channel.
