Series TFX Ultra™ – Clamp-on Ultrasonic Flow & Energy Meter for Liquids

TFX Ultra ultrasonic flow and energy meters clamp onto the outside of pipes and do not contact 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. TFX Ultra is available in a variety of configurations that permit the user to select a meter with features suitable to meet particular application requirements.

The TFX Ultra is available in two versions: a stand-alone flow meter, and an energy flow meter used in conjunction with dual clamp-on RTDs. The energy flow meter measures energy usage in BTU or Tons, and is ideal for retrofit, chilled water and other HVAC applications.

Features of the TFX Ultra include:

• Ability to measure liquids with small amounts of suspended solids or aeration (e.g., surface water, sewage).
• Bi-directional flow measurement system. Totalizer options include forward, reverse and net total.
• Modbus RTU over RS485 communications; Ethernet connection includes BACnet/IP^®, EtherNet/IP™ and Modbus TCP/IP protocols.
• Compact enclosure uses large, easy-to-read digital display.
• Rugged, aluminum enclosure ensures a long service life in harsh environments.

Series TFXL – Non-Invasive Small-Pipe Flow Meter

Series TFXL is an ultrasonic flow meter that clamps on to the outside of a pipe. It is designed to replace mechanical flow meters in applications where liquid conditions tend to damage or impede mechanical flow meter operation. Installation of the TFXL is cost effective and the meter requires no maintenance. The unit may be ordered with or without a local display. All meters provide two flow rate outputs: 4-20 mA analog and simulated turbine meter frequency, permitting the product to be interfaced with a variety of monitoring equipment. ULTRALINK™, a Windows^® -based software utility, allows users to configure, calibrate and troubleshoot.

The TFXL integral mount flow meter is offered on pipe sizes from 1/2" (12mm) to 2" (50mm). It is also available as a remote mount system for small pipes from 1/2" (12mm) to 2" (50mm) and large pipes from 2" (50mm) and up.

Additional features of the TFXL include:

• May be used to measure liquids with moderate amounts of suspended solids or aeration (e.g., well water, sewage).
• Bi-directional flow measurement system. Totalizer options include forward, reverse and net total.
• ULTRALINK™ software utility enables in-field flow meter configuration, calibration and troubleshooting via laptop PC.
• Automatic correction settings for applications where high amounts of entrained gases are present.
• Compact enclosure uses large, easy-to-read digital display.

Series DFX Flow Meter

Series DFX Ultrasonic Doppler Flow Meters measure flow of liquids that contain useful sonic reflectors¹suspended within the liquid. The DFX flow meter operates by transmitting an ultrasonic sound from its transmitting transducer through the pipe wall into the flowing liquid. The sound will be reflected by the the reflectors and recorded by the receiving transducer. The clamp-on style transducer is also available in small pipe and high temperature options. The DFX also offers an insertion probe transducer for pipe systems that do not permit ultrasound penetration.

The Series DFX replaces the 601, 901, and 770 models; using more advanced technology for easier installation and more reliable readings on a wide range of liquid and reflector conditions. Unlike other Doppler technologies, the Series DFX is relatively insensitive to VFDs and other ultrasonic noises.

Standard features of the DFX include:

• Non-intrusive, clamp-on design
• Flow ranges from 0.15 to 30 FPS (0.05 to 9 MPS)
• User-friendly, field programmable
• Resettable 8-digit LCD totalizer
• Field configurable AC/DC power supply
• NEMA 4X (IP66) enclosure
• Pipe sizes from 0.25 inches (6 mm)
Optional outputs include:  4-20 mA, dual relay and rate pulse

• Maintain a sonic impedance (sound speed difference) different from the fluid
• Contain some particles large enough to cause longitudinal reflection - particles larger than 35 micron
• Longitudinal reflection has sufficient energy to overcome the Rayleigh (energy wasting) scattering caused by smaller particles
• Travel at the same velocity as the fluid

Series 902 Portable

Series 902 offers our enhanced Doppler technology in a portable case designed for rugged field use. The rechargeable battery housed inside the 902 enclosure provides a full eight hours of continuous operation. The standard configuration provides everything necessary to measure flow in pipes ranging from 1 to 120 inches (25 to 3050 mm). An optional small pipe transducer can be applied to pipes from 0.125 to 1 inch (3 to 25 mm).

Other features of the Series 902 include:

• Non-fouling transducers are immune to build-up of grease, paraffin and other coating materials
• Operates with relatively clean liquids as well as liquids with concentrations of suspended solids or aeration, minimum of 25 PPM of 30 micron size
• Does not require long straight runs of pipe
• Standard 4-20 mA output for chart trending
• Solid state measurement reduces calibration requirements and is virtually maintenance free
• Operates on pipes ranging from 0.25 to 120 inches 
  (5 to 3050 mm)

Series UFX Hand-held Flow Meter

Series UFX Doppler Flow Meters provide accurate and reliable flow velocity assessments in closed pipe, liquid systems.  UFX requires that the liquid be either solids-bearing or aerated at a minimum of 100 ppm.  The product utilizes a single, hand-held transducer which is placed on the outside of metal or plastic pipe.  Within seconds after placing the transducer, the large LCD will provide a velocity reading in either FPS (feet per second) or MPS (meters per second).  The UFX comes with a flow calculator/slide chart for conversion of velocity measurements to popular volumetric measurements.

Standard features of the DUFX include:

• Flow ranges from 0.3 to 30 FPS (0.1 to 9 MPS)
• Optional CE mark - rated for light industrial service
• Protective carrying case includes everything required to make measuements
• Digital LCD flow rate indication
• Rugged splash-proof enclosure
• Pipe sizes from 0.25 inches (6 mm)
• Accuracy of ±2% of full scale

FUSION^®

The Dynasonics Fusion Hybrid Flow Meter utilizes both Doppler and transit time ultrasonic sound techniques and automatically selects the correct technology to calculate the flow rate.  This dual technology allows the Fusion to accurately measure the volumetric flow of clean, solids-bearing or gaseous liquids on full pipes. Adverse flow conditions – surges, particulate, gas pockets, etc. – will not clog, damage or influence accuracy of the “flow-through” Fusion design. The stainless steel sensor contains no moving parts to wear or degrade, so product maintenance, repairs and calibration intervals are eliminated.

All Fusion meters come completely calibrated and sensors are pre-installed in a spool piece for easy and quick installation into existing piping systems. A simple keypad interface permits measurement unit selection and output spans to be adjusted.

Features of the Fusion include:

• Automatically switches between Doppler and transit time to determine best technology and calculate accurate flow rates
• Utilizes flow-through stainless steel flow sensors
• Rugged, all metal construction ensures a long service life in harsh outdoor environments
• Simultaneous display of flow rate and accumulated total on a large, easy to read LCD display
• Total reset through keypad, RS485 command or momentary contact of a terminal block connection to ground
• Modbus command set permits flow rate, total and total reset access
• All configuration parameters and flow totals are backed up indefinitely in FLASH memory
• Outputs include 4-20 mA, RS485 (Modbus), rate pulse and total pulse
